Description

[0001] METHODS FOR PRODUCTION OF ASPHALT TYPE MATERIALS AND ASPHALT

[0002] PAVINGS, ASPHALT TYPE MATERIALS FOR PAVING, AND USE OF THE METHODS AND ASPHALT TYPE MATERIAL

[0003] Technical Field

[0004] The present invention relates to paving such as asphalt paving on roads and other areas.

[0005] Background Art

[0006] Asphalt and paving are widely used in the modern world, covering roads, parking areas and numerous other areas. Asphalt paving is typically made by mixing sticky, heavy bitumen materials with solid rock particles, by heating and mixing the whole mass of rock materials and bitumen in a mixer. The rock particles used as solid particulate materials with particles of fixed shape, in one or several size fractions, contribute to wear resistance and stability. Said particles will typically require drying by heating before further comprehensive heating and mixing with bitumen.

[0007] Extensive testing, experience and development over many decades have resulted in modification to the general method briefly described above, by first heating and mixing the larger rock particles with bitumen in a mixer, after which smaller particles and optionally further bitumen are added to the mixture already in the mixer. Reference is made to patent publications EP 0 756 615 B1 and EP 1 586 706 B1 , including description of methods enabling reduced tendency to cracking and rutting in a paving built by the resulting mixture, thereby prolonging the paving service life. The mixing takes place in a mixer with a fixed volume for mixing, and the whole mixture is comprehensively mixed and heated to the mixing process temperature. Very close control of the mixing times and adding of smaller particulates after coarser particulates, enable improved paving quality with reduced tendency to cracking and rutting. Larger particulates are added first, then smaller particulates, for ensuring that the larger particulates are completely covered by bitumen, which according to experience, is essential for producing quality materials resulting in quality paving.

[0008] The quality of paving has a significant effect on emissions and pollution. When an asphalt paving, such as a road, is subject to wear, much material is released from the paving itself and also from the tires of cars and heavier vehicles. With the increase in relatively heavier vehicles driving by electricity from very heavy batteries, with large torque due to electric motors with maximum torque from start, the result is increased pollution from paving and tires. The pollution includes tar-like particulates and substances, including compositions known to have severe effect on health, and microplastics from the tires, in addition to small rock fragments or dust disturbing breathing function of many forms of life. The pollution ends up in ecosystems in water and on land, and in living organisms, probably affecting numerous forms of life, including humans, more than fully understood.

[0009] The emissions resulting from the production process, including the energy used for the production and transport, is also a significant factor when considering a paving. Traditionally, the asphalt mixture is contained and transported into flatbed trucks with specialized vehicles with insulated non-heated and non-rotating half pipe tarpaulin bed or closed containers with internal mixing paddles and heating for more liquid type asphalt.

[0010] If possible, it would be favorable with asphalt type materials and paving and a method for producing such materials and paving requiring less energy for production, enabling simplified and improved storage and transport, enabling storage and / or transport of prefabricated paving material of various volumes and shapes, facilitating building, repair and maintenance, improving service life of the resulting paving, with less creep, buckling, surface depressions, rutting and / or cracking. The paving would thereby be improved, if taking all aspects into consideration, and the service life of tires and cars may also be prolonged. The objective of the present invention is to contribute favorably with respect to one or more of the issues mentioned above.

[0011] Summary of the invention The objective is met by the present invention.

[0012] The invention provides a method for producing asphalt type material for paving, distinguished by comprising the steps: to provide dry, solid particulate material, of various sizes, such as from 1 to 32 mm diameter, or of uniform size: to arrange a first layer of said dry solid particulate material, preferably as unheated, i.e. at ambient temperature, on a production table or other production structure; to arrange bitumen material, in the form of fossil bitumen or bio bitumen or mixtures thereof, onto the first layer of solid particulate material, wherein the bitumen material is at temperature above the temperature of the particulate material, wherein the bitumen and temperature of the bitumen are chosen or controlled so as to enable the bitumen to flow around and cover the particulate material on the production table or other production structure, under which a collector for surplus bitumen (6) is placed as found convenient, by flow by gravity and any vibrations on the particulate material induced from the production table or other production structure, providing a first layer of bitumen covered solid particulate material; and to arrange a new layer of dry solid particulate material, preferably as unheated, on the first layer of bitumen covered solid particulate material on the production table or other production structure, and arranging bitumen onto the new layer of particulate material, covering the new layer of particulate material with bitumen, and repeating the step until the intended number of layers of bitumen covered particulate material has been provided; or to arrange a first layer of in substance identical size particulate material on the production table or other production structure, coating said particulate material with a layer of slick material before arranging or when arranged on the production table or other production structure, and to arrange bitumen material, in the form of fossil bitumen or bio bitumen or mixtures thereof, onto the layer of solid particulate material coated with slick material, and repeating the step as convenient, by arranging a next layer onto the previous layer, until an intended thickness has been provided.

[0013] The invention also provides asphalt type materials produced by the method, with or without inherent draining functionality. The draining functionality is provided by some embodiments resulting in asphalt type material for paving with inherent open porosity, enabling draining through the open porosity.

[0014] The dry, solid particulate material, preferably of various sizes, or uniform size, such as chosen from 32, 22, 16, 11 , 8, 5, 4, 2, 1 , 0,5, 0,25, 0,125 and 0,063 mm diameter, representing standard sieve fractions. Larger sizes, or unsorted or partly or roughly sorted particulate material with respect to size, are also possible to use, of which unsorted or partly or roughly sorted material can reduce cost.

[0015] Two main embodiments of the method exist, and the resulting asphalt paving, namely with or without inherent draining function.

[0016] The most preferred method resulting in the most preferred asphalt paving without inherent draining, is by using dry, solid particulate material of various sizes, wherein the size of the particulate material decreases upwards from the first layer of bitumen covered solid particulate material, preferably successively for each layer of bitumen covered solid particulate material and / or in steps including two or more layers with one size of solid particulate material. Said method provides asphalt paving with maximum service life at reduced energy consumption and emissions for production.

[0017] The most preferred method resulting in asphalt paving with inherent draining, is by using dry, solid particulate material of in substance identical size, wherein said dry, solid particulate material of in substance identical size has been or is coated with a layer of slick material (i.e. a low friction material retaining less bio bitumen and / or fossil bitumen), said particulate material coated with slick material is arranged as a layer on the production table or other production structure or is coated with said slick material after being arranged on the production table or other production structure, to arrange bitumen material, in the form of fossil bitumen or bio bitumen or mixtures thereof, onto the layer of solid particulate material coated with slick material, and optionally repeating the steps by arranging a next layer onto the previous layer, until an intended thickness has been provided, whereby an asphalt type paving material with inherent draining capability is resulting.

[0018] Preferably, the slick material is bio bitumen, preferably a harder quality and warmer when applied than the bitumen later applied for binding, and / or bitumen containing dust from stones, wax, polymer resins, or other additives for reduced adherence and friction, or mixes thereof. A top slick layer, or the only slick layer, preferably comprises dust from stones, wax, harder bitumen or harder bio bitumen. Preferably, a layer of fine dust, from aggregates and / or polymers and / or hard rubber, can be applied before applying further bitumen, for reducing the stickiness and resulting thickness of softer bio bitumen or other bitumen for binding.

[0019] In substance identical size means solid particulate material covering 3 sieve sizes, more preferably 2 sieve sizes, most preferably only one sieve size. A key feature is that voids cannot be filled with smaller size aggregates since such smaller size aggregates are not included, and the slick layer reduces the thickness of bitumen adhering, resulting in remaining open porosity for draining.

[0020] Draining functionality is provided also for several layers of uniform size slick material coated solids and / or decreasing size upwards slick material coated solids, but with best drainage when using only one size of slick material coated particulate material in only one relatively thick layer. Each individual stone or aggregate particle will contain the entire recipe, and the asphalt mass cannot be divided into different particle sizes in the most preferred embodiments with identical size particles.

[0021] For the method, if using bio bitumen extensively, binding more carbon than emitted by the fossil bitumen (if present at all) and the production and laying of the asphalt paving in sum, the resulting asphalt paving will be carbon negative.

[0022] Dry solid particulate material means solid particulate material without moisture or water contents at a level significantly reducing the ability to cover the particulate material with bitumen, as prescribed by the present invention. Maximum moisture / water contents / humidity is about 1 % by weight, at which level the largest rock fragments or stones (solid particulate material) are observed as wet but significant evaporation takes place during the production method before the next layer of bitumen covers the stones / rock fragments. Most preferably, the rock fragments are without any visible moisture / water contents / humidity, and without any other visible layers reducing the covering of bitumen on the rock fragments.

[0023] Preferably, a production table is where the production takes place. Preferably in an inclined production table, preferably within 1-50° or 10-45° downward from horizontal, in longitudinal direction, parallel to which way material on the table is moved.

[0024] Preferably, the production table can be vibrated, preferably including longitudinal members that can be vibrated. However, production can take place directly in storage and transport bags or containers, or directly into for example a cavity on a road, or onto a worn-out existing paving or road structure, all of which are examples on “production structure”.

[0025] For the method of the invention, no mixer is required, and preferably no mixer is used. In state-of-the-art asphalt type material production, a mixer is used, mixing and heating all the material from ambient temperature. About 94% of the material in an asphalt paving is solid particulate material that shall retain a fixed shape. The method of the invention requires no direct heating of the solid particulate material and preferably is without any direct heating of the solid particulate material, meaning that heating thereof is merely indirectly from the warmer bitumen.

[0026] In a preferable embodiment, the feeding and transportation is continuously, wherein the feeding position of the first layer of dry unheated particulate material is arranged upstream to the feeding station of bitumen, relative to the direction of motion of the production table in the form of a transport band, arranging said materials across the width of the production table, followed in downstream direction by further feeding stations of dry yet unheated particulate material and further bitumen feeding stations.

[0027] In another preferable embodiment, the feeding and transport is batchwise, wherein the layer of dry unheated particulate material is distributed evenly along and across a production table not being a transport band, followed by distribution of a layer of warmer bitumen on top, wherein the bitumen flows down on and around the particulate material, followed by further layers of dry unheated particulate material and bitumen on top of previous layers, successively building up the layers, until completed.

[0028] For the method of the invention, the temperature controls the resulting thickness of the bitumen layer. Far thicker layer or layers than possible in a traditional asphalt mixer is possible.

[0029] Preferably, a filler is added, preferably as pre-mixed into the bitumen. Preferably, a fiber material is added, preferably as pre-mixed into the bitumen. Different bitumen or bitumen mixtures and / or temperature can be used for each layer.

[0030] Preferably, the feeder or feeders comprise a transport / feeding screw, a vibro feeder, and / or a distribution feeder or other feeder, wherein the feeders are arranged at intervals along length of the transport band, arranging over the width of the transport band, for continuous feeding on a transport band production table, and / or operatively arranged along the width and length of the transport band for batchwise feeding, for example on a static production table not transporting the material in a longitudinal direction of the production table.

[0031] Preferably, the bitumen for feeding is typically at 60° C or warmer, up to about 200° C can be feasible. More specifically, a bitumen feed temperature where flow of bitumen for covering the solid particulate material as intended takes place is required, which in practice is subject to testing to define, but has a correlation to stickiness and “stiffness”, but no general correlation for all bitumen qualities exist. More specifically, ambient temperature and the maximum temperature in summer on a sunny day, must not heat the asphalt paving into temperature at which the paving becomes sticky. In warm climes, a stiffer bitumen is used, and in colder clime a softer bitumen. For example, a softening point temperature of the bitumen quality chosen preferably is above the maximum operation temperature of the asphalt type paving produced, more specifically the operating temperature of the bitumen is softening point temperature + 20, 30, 40 or 50° C, or higher. Numerous tests and standards exist, and numerous qualities of bitumen, fossil and bio bitumen, but apparently no test directly finding the maximum feasible operating temperature of a bitumen material. Testing can be required for correlating and determining levels of stickiness, as a function of temperature, and other parameters, such as minimum operating temperature without tendency of cracking, using one or more of the methods and standards referred to in the detailed description, or other similar methods, or simply by testing in field.

[0032] Preferably, the produced layer is cooled down to a storage and transport temperature, preferably to a temperature below a stickiness temperature, facilitating storage and transport thereof. In some embodiments, the method is further comprising to cover a production table with a layer, preferably a non-sticky layer on the underside, using the layer with non-sticky underside as a layer onto which asphalt paving is stored, in one or several layers. Preferably, if a broken cooling chain or very high ambient temperature, a layer of dry, unheated sand or other particulate or fibrous material is arranged as a top layer. Depending on the transport and storage methods, a layer of bitumen can preferably be the top layer, i.e. with cooling during storage and transport, or with temperature for sticking above ambient temperature all the time. Storage in water, freezer, cold weather or snow are preferred methods, due to natural ambient temperatures below stickiness and hydrophobic properties of the asphalt type material and asphalt type paving.

[0033] The bitumen preferably includes fine solid particulate material, such as rock particulates of size below 1 mm, and / or filler materials of size below 0,0063 mm diameter, and / or materials for controlled stickiness, such as amines, which materials can be adjusted in quantity, size and / or type for improved control of stickiness, such as for each job or layer.

[0034] Preferably, two or more layers of solid particulate material covered with bitumen is produced, wherein the size of the particulate material decreases successively for each layer, or in steps including several layers with one size of solid particulate material.

[0035] The production table preferably is an inclined production table or an inclined transport band, or a sieve mesh or longitudinal elements or wires, or the production structure is a production tub or a production bag, such as a silicon rubber or ptfe (Teflon) coated tub or, into or onto which production structure the asphalt type material can be produced. However, in many embodiments, water and / or snow are preferred for storage and / or transport.

[0036] The invention also provides a method for producing asphalt paving, asphalt joints or similar structure, wherein the asphalt type material used is produced by the method of the invention, distinctive by that the asphalt type material is applied directly into the cavity or on the surface to be built, without heating or optionally with heating by warm air, steam, warm water or otherwise, followed by rolling or other compressing for forming to shape and reducing or eliminating voids, and optionally followed by applying a top layer of warm or cold sand or small size particulate materials.

[0037] The invention also provides an asphalt type material for paving, filling cavities in roads or other surfaces, and filling joints, produced by the method of the invention, distinctive in that the asphalt type material comprises a layered structure of particulate materials covered by bitumen type material, wherein the size of the particulate material decreases from the bottom to the top, continuously or in steps, enabled since the material has never been mixed in a mixer, or is identical in size.

[0038] The invention also provides use of the methods of the invention, and the asphalt type material of the invention, for building or repairing asphalt type paving, joints and filling into and repairing cavities, rutting cracks and similar defects in asphalt type paving.

[0039] Figures

[0040] Figure 1 illustrates the method and the asphalt type materials of the present invention.

[0041] Detailed Description

[0042] Reference is made to Figure 1 , illustrating an inclined process table 5, in the form of a transport band 5, for production of asphalt type material of the invention by the method of the invention. A vibroplate 2, arranged near the end of the highest position of the inclined transport band 5 distributes a largest fraction 9 of solid particulate material, the largest stone 9, over the width of the transport band 5. Above the vibroplate 2 is a material feeder 1 , a clean stone fraction 9,10, also termed solid particulate material, in the fraction size for the specific position. Further down, a bitumen nozzle 4 distributes bitumen over the largest fraction of solid particulate material 9, over the full width thereof on the transport band, under which a collector for surplus bitumen 6 is placed. Further down the inclined transport band, a collector 7 of surplus solid material is placed, on the underside of the transport band. Further down the transport band, further way from the highest end, further stations for solid particular material, of smaller size particulate material 10 are arranged, similarly with with bitumen nozzles 4 above the transport band and bitumen collector 6 and stone collector 7 below the transport band, operatively positioned as for the largest stones but further down the transport band from the highest end thereof. Only some of the stations and collectors are illustrated for illustrating the principle clearly. There is in principle at least one solid particulate material feeder, one bitumen feeder and at least one collector for each of bitumen and stone for each layer of bitumen covered solid particulate material in the end product. At least one vibromotor 2 is operatively arranged for each vibroplate and the process table, such as directly below each vibroplate and the process table.

[0043] At the end of the transport band, the produced asphalt type material is cooled down to a temperature when it is no longer sticky and transported away 8 as cold transportation to a site for packaging, transport and / or building / repairing and / or storage. The illustration is not to scale and features are simplified for increased clarity. The produced asphalt type material 11 is usually not shaped as a clump of asphalt type material, as illustrated, but is more often in the form of a complete layer of asphalt type material, ready for cold transport and laying on an underlayer, preferably aided by warm air, warm water or other feasible moderate heating for ensuring firm binding to the underlayer.

[0044] As the person skilled in the art will understand, the asphalt paving of the invention must be non-sticky when in position for operation, that is for traffic of vehicles of various types, and pedestrians. Due to the bitumen, asphalt paving is often black, absorbing maximum of solar radiation, resulting in high maximum temperature on sunny, warm summer days. Uncertainty exists on how warm the asphalt paving will be on the warmest and sunniest days, but as an example 50° C can be assumed. In cold areas, a lower maximum temperature is likely, such as 40° C, in warmer areas a higher maximum temperature is likely, such as 60-80° C and perhaps higher.

[0045] The temperature for when asphalt paving become sticky must be above the local maximum asphalt paving temperatures, by a margin, such as 5° C, 10°C, 20° C or 30° C higher. No directly usable test method apparently exists, so field testing can be required for determining correct softness-hardness-stickiness as a function of temperature, for a specific use of the asphalt paving. The correlations are not necessarily linear or constant. Amongst many more or less relevant tests, NS-EN 1427:2015; Bitumen and bituminous binders — Determination of the softening point — Ring and Ball method, can be used for finding a reference temperature that presumably has a correlation to the required maximum operating temperature of the resulting asphalt paving material. Testing according to NS-EN 1427:2015 finds the temperature at which a steel sphere can be pressed through a bitumen-filled ring until it hits a plate below. The test takes place in water, typically at 40 - 95° C for traditional testing, but for testing materials of the invention, increased temperatures are perhaps more feasible, since asphalt paving can reach a temperature of at least about 80° C in the south of Europe.

[0046] Accordingly, the temperature of the test according to NS-EN 1427:2015, with a margin plus or minus, should be a clear guidance of how stiff the asphalt paving must be to be feasible for a specific use in a specific area, that is with sufficient stiffness combined with not being sticky. Appropriate margin can be ±10°C, 20° C or 30° C higher. However, field testing should be undertaken to determine exact correlation, and to provide experience data.

[0047] Other tests or standards, more or less feasible, can be according to NS-EN 13108- 1 :2016, with typical fractions of 32, 22, 16, 11 , 8, 5, 4, 2, 1 , 0,5, 0,25, 0,125, 0,063. Fillers are within 0 - 0,063mm. NS-EN 13108-4:2016 defines Bituminous mixtures - Material specifications - Part 4: Hot Rolled Asphalt, published November 2016. NS-EN 12593:2015 relates to Bitumen and bituminous binders — Determination of the Fraass breaking point, related to risk for cracking, can apparently be a reference test correlating to the minimum operating temperature of asphalt paving material of the invention without risk for cracking. NS-EN 1426:2015 relates to Bitumen and bituminous binders — Determination of needle penetration, wherein quality of for example 70 / 100 define 1 / 10mm penetration of a needle with 100g load within 5 seconds, with bitumen at 25° C.

[0048] In many preferable embodiments of the present invention, bio bitumen and natural asphalt are mixed and used as bitumen, resulting in a surprisingly hard bitumen and at the same time a bitumen with eliminated, reduced or negative carbon emission. The most preferable bio bitumen appears to be according to the teaching of patent publication EP 3208 288 B1. Preferably, said bio bitumen is mixed with natural asphalt (or bitumen) with about 1 part bio bitumen to about 3 parts natural asphalt.

[0049] Bitumen qualities or compositions, in general includes one or more of, in any combination: fossil, bio, polymer, synthetic, modified, crumb rubber bitumen, plastic bitumen, emulsions, polymerized, oxidized and / or colored.

[0050] Not standardized size fractions and / or materials can also be used, which can reduce cost. Decreasing size upwards from the lowermost first layer of bitumen covered particulate material, must anyway have decreasing average or median size of the particles in layers upwards from the first layer.

[0051] Dry solid particles, sieved in air and without excessive humidity, are commercially available from modem crushing plants or from modem mortar plants.

[0052] The most preferable asphalt paving material of the invention become sticky at temperature above the maximum operating temperature, as related and correlated to said softening test or as found by field testing, and become brittle with tendency of cracking at temperature below the minimum operating temperature, as related and correlated to said Fraass breaking point test or as found by field testing.
