Problems solved by technology

Among them, re-paving after re-excavation is expensive and affects the overall aesthetics of the road surface; although asphalt respraying on poor oil roads is simple and efficient, it has poor durability, generally 1 to 2 years, and the amount of resprayed asphalt is not properly controlled. Causes oil flooding on the pavement surface; while slurry seal and micro-surface seal will increase the design elevation of the pavement, resulting in damage to the integrity of the pavement

preparation example Construction

[0031] The present invention also provides the preparation method of asphalt pavement pockmarked surface repair material described in above-mentioned technical scheme, comprises the following steps:

[0032] (1) mixing the emulsifier with part of the water to obtain an emulsion;

[0033] (2) mixing the emulsion obtained in the step (1) with clay to obtain a mud type emulsified soap;

[0034] (3) Mix the mud-type emulsified soap liquid obtained in the step (2) with asphalt, acrylic resin and remaining water in sequence to obtain a patching material for asphalt pavement.

[0035] In the present invention, the emulsifier is mixed with part of the water to obtain the emulsified liquid. In the present invention, based on 100 parts of pitch, the part of water preferably has a mass of 120-200 parts, more preferably 140-180 parts. In the present invention, the temperature of the water is preferably 90-95°C, more preferably 93°C.

[0036] In the present invention, there is no specia...

Embodiment 1

[0052] Raw material ratio: 35 parts of clay, 100 parts of asphalt (road petroleum asphalt, softening point: 58°C), 120 parts of hot water, 5 parts of anionic emulsifier (sodium dodecylbenzenesulfonate), 40 parts of cold water; acrylic resin (solid content 40%) 10 parts;

[0053] Preparation:

[0054] Step 1: Fully stir the emulsifier and hot water (90°C) (rotate at 100r / min, stir for 3min);

[0055] Step 2: Add clay into the mixed solution formed by emulsifier and water and continue to stir (rotating speed 280r / min, stirring for 7min) to make mud type emulsified soap liquid;

[0056] Step 3: Add hot asphalt (135°C) into the mixing tank, and stir until the asphalt is added (speed 280r / min, stirring for 20min);

[0057] Step 4: Add acrylic resin and stir while adding (speed 250r / min, stirring for 3min);

[0058] Step 5: add cold water to adjust the viscosity and control the viscosity range from 1400 to 2300 centipoise.

[0059] According to ASTM D2939, the asphalt pavement p...

Abstract

The invention provides an asphalt pavement pitted surface repairing material, a preparation method thereof and an asphalt pavement pitted surface repairing suspending sand material. The asphalt pavement pitted surface repairing material is prepared by, by mass, 100 parts of asphalt, 5-8 parts of emulsifier, 30-50 parts of clay, 10-15 parts of acrylic resin and 150-250 parts of water. The asphalt pavement pitted surface repairing material has the advantages that the clay, the emulsifier and the water are used to form slurry type emulsification soap liquid used for emulsifying asphalt so as to allow components to be combined to form an integrated whole and increase the viscosity of emulsified asphalt, the asphalt pavement pitted surface repairing material can replace asphalt pavement surfaceoil to be mixed with fine aggregates during use, the loose aggregates can be locked under a low-thickness condition, influence on pavement elevation is avoided, damage, caused by oxidation, weather and traffic, to the original pavement is prevented, and the service life of the pavement is prolonged.

Description

technical field [0001] The invention relates to the technical field of road maintenance, in particular to an asphalt pavement pockmarked surface repair material, a preparation method thereof and a suspended sand material for asphalt pavement pockmarked surface repair. Background technique [0002] During the paving process of asphalt concrete pavement, the life of asphalt pavement is often damaged due to improper control of the ratio of oil to rock. Asphalt pavement with insufficient oil content, with the erosion of rainwater, the binder gradually loses its cohesive force, the aggregate loosens, causing the pavement to become loose, and further deteriorates, fine aggregates will fall off, rough pits will appear on the pavement, and even pits will develop. affect driving comfort. [0003] Most of the traditional methods of repairing pockmarked and loose asphalt pavements are to sprinkle asphalt on the oil-poor surface course or adopt slurry sealing and micro-surfacing techno...
