Description

Technical Field

[0001] The invention relates to the technical field of garden construction, in particular to a garden landscape road and a construction process thereof. Background Art

[0002] With the acceleration of urbanization and the continuous improvement of people's requirements for the quality of living environment, the status of garden landscape in urban construction has become increasingly prominent. Garden landscape is not only a place for people to relax and entertain, but also an important part of the urban ecosystem.

[0003] As the vein of the garden, the function of the landscape road is no longer limited to simple traffic connection, but needs to take on more roles. It needs to be integrated with the surrounding natural and cultural landscapes to provide tourists with a comfortable and beautiful walking experience.

[0004] During the construction process of existing garden landscape roads, they are usually made of cement concrete and marble, which makes the surface of the road relatively smooth. On rainy days, the top of the road becomes more moist and smooth under the influence of rain, causing vehicles or pedestrians to slip or fall easily when moving along the road, thereby reducing the safety of the garden road. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a garden landscape road and a construction process thereof, which solves the problem that the existing garden landscape roads are mostly built of cement concrete and marble materials, the road surface is slippery, and it is even worse on rainy days, which easily causes vehicles and pedestrians to slip and fall, thereby reducing the safety of the garden road surface.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A garden landscape road, comprising 70%-75% asphalt concrete base layer and 25%-30% anti-skid surface layer;

[0007] The asphalt concrete base is specifically composed of: 40%-50% coarse aggregate, 30%-35% fine aggregate, 4%-6% asphalt, and 3%-5% mineral powder;

[0008] The anti-skid surface layer specifically comprises: 20%-30% of colored anti-skid ceramic particles, 10%-15% of modified asphalt binder, 30%-40% of fine aggregate, and 1%-2% of fiber material.

[0009] A construction process for a garden landscape road comprises the following steps:

[0012] S3. Material mixing: Use a mixer to mix the asphalt concrete base materials according to the proportion to ensure the good fluidity and adhesion of the asphalt and make the mixture reach the best performance state;

[0013] S4. Base layer paving: Use a paver to evenly spread the stirred asphalt concrete mixture on the cleaned base layer. During the paving process, control the speed and paving thickness of the paver;

[0014] S5. Compacting the base: After paving is completed, use a roller to compact the base immediately;

[0015] S6. Surface paving: Spread the anti-skid surface mixture on the asphalt concrete base by manual paving using paving tools. The thickness is controlled according to the design requirements so that the anti-skid surface accounts for 30% of the total thickness.

[0016] S7. Surface compaction and finishing: Use the roller again to compact the anti-skid surface. After compaction, the staff will use the trimmer to smooth the uneven surface according to regulations to form a good anti-skid texture.

[0017] Preferably, in step S1, the construction equipment includes a mixer, a paver, and a roller.

[0018] Preferably, in step S3, the stirring speed of the stirrer is 30-50 r / min, the stirring time is 30-60 s, and the stirring temperature is 150-170°C.

[0019] Preferably, in step S4, the travel speed of the paver is generally controlled at 2-6 m / min, and the paving thickness is adjusted according to the design requirement that the base layer accounts for 70%-75% of the total thickness.

[0020] Preferably, in step S5, the speed of the roller is 1.5-3 km / h, and static compaction is performed 1-2 times to stabilize the mixture. After waiting for 3-5 hours, the base layer is re-compacted with the roller, and the compaction speed is controlled at 3-5 km / h, and the roller is rolled 4-6 times.

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 It is a construction process flow chart of the present invention. DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1:

[0031] Please see attached Figure 1 , an embodiment of the present invention provides a garden landscape road, including 70% asphalt concrete base layer and 30% anti-skid surface layer;

[0032] The asphalt concrete base is specifically composed of: 40%-50% coarse aggregate, 30%-35% fine aggregate, 4%-6% asphalt, and 3%-5% mineral powder;

[0033] The anti-skid surface layer specifically comprises: 20%-30% of colored anti-skid ceramic particles, 10%-15% of modified asphalt binder, 30%-40% of fine aggregate, and 1%-2% of fiber material.

[0034] A construction process for a garden landscape road comprises the following steps:

[0035] S1. Preparation for base construction: Prepare corresponding construction materials according to design requirements, including coarse aggregate, fine aggregate, asphalt, mineral powder, colored anti-skid ceramic particles, modified asphalt binder and fiber materials, and prepare construction equipment, including mixer, paver and roller;

[0036] S2. Base site cleaning: Clean the construction site of the landscape road, remove debris, garbage, and vegetation in the site, clean and level it, and ensure the flatness and stability of the base construction;

[0037] S3. Material mixing: Use a mixer to mix the asphalt concrete base material according to the proportion. The stirring speed of the mixer is 30-50r / min, the stirring time is 30-60s, and the stirring temperature is 150-170°C to ensure good fluidity and adhesion of the asphalt and make the mixture achieve the best performance state;

[0038] S4. Base paving: Use a paver to evenly spread the stirred asphalt concrete mixture on the cleaned base site. During the paving process, control the driving speed and paving thickness of the paver. The driving speed is generally controlled at 2-6m / min. The paving thickness is adjusted according to the design requirements that the base accounts for 70% of the total thickness to ensure the flatness of the paving;

[0039] S5. Compacting the base: After paving is completed, use a roller to perform initial compaction on the base immediately. The speed of the roller is 1.5-3 km / h, and static compaction is performed 1-2 times to stabilize the mixture. After waiting for 3-5 hours, use a roller to perform recompacting on the base. The compaction speed is controlled at 3-5 km / h, and the compaction is performed 4-6 times.

[0040] S6. Surface paving: Spread the anti-skid surface mixture on the asphalt concrete base by manual paving using a scraper or rake. The thickness is controlled to 30% of the total thickness according to the design requirements.

[0041] S7. Surface compaction and finishing: Use the roller to compact the anti-skid surface again. The speed of the roller is 1-2 km / h, and it is rolled 2-3 times. After compaction, the staff uses a trimmer to smooth the uneven surface to control the flatness error within ±3mm, ensuring that the ceramic particles are evenly distributed on the surface to form a good anti-skid texture.

[0042] Beneficial effects of Example 1: Through a special ratio, an anti-skid surface layer is added to increase the friction between vehicle tires and pedestrian soles and the top of the road, thereby achieving an anti-skid effect, further ensuring safety, so that the garden landscape road has good anti-skid performance while ensuring its beauty, meeting the safety requirements of pedestrians walking and small vehicles driving.

[0043] Embodiment 2: A garden landscape road, comprising a base layer of 75% and an anti-skid and permeable surface layer of 25%;

[0044] The base layer specifically comprises: 40% crushed stone, 30% coarse sand, 8% cement, and 2% water-permeable additive;

[0045] The anti-skid and water-permeable surface layer specifically comprises: 60% of colored water-permeable concrete, 20% of anti-skid ceramic particles, 1% of reinforcing fiber, and 19% of adhesive.

[0046] Beneficial effects of Example 2: On the basis of Example 1, by changing the material ratio of the base layer and the anti-skid and permeable surface layer, the base layer can ensure the load while having a larger pore size, thereby enhancing the drainage effect of the road. While the anti-skid and permeable surface layer ensures the anti-skid effect, the pore structure of its inner wall can allow rainwater to pass quickly, further improving the permeability of the road.

[0047] Embodiment 3: A garden landscape road, comprising 67% of a base layer and 33% of an anti-skid sound-absorbing surface layer;

[0048] The base layer specifically comprises: 50% graded crushed stone, 30% sandy soil, 10% cement stabilized soil additive, and 10% rubber particles;

[0049] The anti-skid and sound-absorbing surface layer specifically comprises: 50% porous asphalt concrete, 20% colored quartz sand, 20% polyurethane adhesive, and 10% sound-absorbing material;

[0050] Beneficial effects of Example 3: Based on Example 1, new functions are achieved through the special material ratio of the base layer and the anti-skid sound-absorbing surface layer. Rubber particles are added to the base layer. The rubber particles have good elasticity and sound absorption properties. They can effectively buffer the pressure when bearing vehicle loads, reduce the impact on the base layer, and absorb the noise generated during vehicle driving. The graded gravel and sandy soil combined with cement stabilized soil additives ensure the structural stability and bearing capacity of the base layer. In the anti-skid sound-absorbing surface layer, the porous structure of the porous asphalt concrete itself works synergistically with the sound-absorbing material, greatly enhancing the sound absorption and noise reduction capabilities, so that the road can effectively reduce noise transmission when vehicles are driving, creating a quiet atmosphere for the surrounding environment.

[0051] Embodiment 4: A garden landscape road, comprising 73% of a base layer and 27% of an anti-skid self-cleaning surface layer;

[0052] The base layer specifically comprises 35% pebbles, 30% medium sand, 25% cement slurry and 10% geotextile;

[0053] The anti-slip self-cleaning surface layer specifically comprises: 60% photocatalytic self-cleaning concrete, 20% corundum, 10% organic silicon waterproofing agent, and 10% nano titanium dioxide coating;

[0054] Embodiment 4 Beneficial effects: Based on Embodiment 1, the base layer of this embodiment adopts a combination of pebbles, medium sand, cement slurry and geotextile. Pebbles and medium sand are used as the main filling materials, and a stable base layer structure is formed under the bonding effect of cement slurry. The larger particle size and gaps of pebbles are conducive to drainage and air circulation, and the geotextile plays the role of isolation and auxiliary drainage, which enhances the stability and durability of the base layer. In the anti-skid self-cleaning surface layer, the photocatalytic self-cleaning concrete contains photocatalytic materials (such as titanium dioxide), which can decompose organic matter (such as oil, dust, etc.) on the surface of the surface layer under sunlight, realize self-cleaning function, reduce labor maintenance costs, and keep the road beautiful.

[0055] Comparative experiment:

[0056] 1. Anti-slip test:

[0057] Experimental equipment and sample preparation:

[0058] Prepare a pendulum friction coefficient tester, and make the garden landscape road specimens of Examples 1, 2, 3, and 4 according to the standard. Make 5 specimens of the same size (such as 300 mm×300 mm×50 mm) for each example, and maintain them to a specified age (such as 28 days) under standard maintenance conditions.

[0059] Experimental process:

[0060] Level the pendulum friction coefficient tester so that the pendulum can swing freely. Place the test piece on the test platform of the instrument so that the surface of the test piece is flat and perpendicular to the swing direction of the pendulum.

[0061] After moistening the rubber slider, place it on the surface of the specimen, start the pendulum, and let it swing freely from a certain height (such as 510mm). Record the friction coefficient value of each swing of the pendulum, with each specimen in a different position.

[0062] Experimental conclusion:

[0063] Embodiment 1: The average anti-skid value is 70-80BPN (swing value), and the friction coefficient is relatively high. This is because the colored anti-skid ceramic particles on the anti-skid surface are combined with modified asphalt binder and other materials to form a rough and stable anti-skid structure on the surface.

[0064] Embodiment 2: The average anti-skid value is 60-70BPN. The anti-skid ceramic particles ensure a certain anti-skid performance. However, due to the pore structure of the permeable surface layer, the anti-skid performance is slightly lower than that of embodiment 1.

[0065] Example 3: The average anti-skid value is 55-65BPN. Although porous asphalt concrete and colored quartz sand can provide a certain friction, due to the need for sound absorption, the structure is relatively loose and the anti-skid performance is affected to a certain extent.

[0066] Example 4: The average anti-slip value is 60-70BPN. Corundum can effectively improve the anti-slip property, but the combined effect of materials such as photocatalytic self-cleaning concrete makes the anti-slip performance slightly inferior to that of Example 1.

[0067]

[0068] 2. Water Permeability Test

[0069] Experimental equipment and sample preparation:

[0070] A pavement permeability coefficient tester was prepared, and five cylindrical test pieces with a diameter of 150 mm and a height of 150 mm were similarly prepared for each embodiment, and cured to a specified age.

[0071] Experimental process:

[0072] Place the test piece into the test tube of the water permeability coefficient tester and seal the gap between the test piece and the test tube with sealing material to ensure watertightness.

[0073] Pour water into the test tube and keep the water level at a certain height (e.g. 100mm). Record the time from the start of water injection to the water level drop to a certain height (e.g. 50mm). Calculate the water permeability coefficient according to the formula (water permeability coefficient = water level drop height × test tube cross-sectional area ÷ (water injection time × specimen upper surface area)). Test each specimen 3 times and take the average value as the water permeability index of the specimen.

[0074] Experimental conclusion:

[0075] Embodiment 1: The water permeability coefficient is about 0.1-0.2 cm / s. Its structure is mainly to ensure anti-slip and base strength, and its water permeability is relatively poor.

[0076] Embodiment 2: The water permeability coefficient is about 0.5-0.8 cm / s. The material design of the base layer and the anti-skid permeable surface layer makes the road have larger pores, can drain water quickly, and has the best water permeability.

[0077] Embodiment 3: The water permeability coefficient is about 0.2-0.3 cm / s. The porous asphalt concrete has a certain water permeability. However, the presence of rubber particles in the base layer and the design to ensure sound absorption and structural stability make the water permeability not as good as that of embodiment 2.

[0078] Embodiment 4: The water permeability coefficient is about 0.1-0.2 cm / s. The use of materials such as geotextile and cement slurry is mainly for the stability of the base layer and drainage assistance. The anti-skid self-cleaning surface layer has limited water permeability in order to ensure the self-cleaning and anti-skid functions.

[0079]

[0080] 3. Noise prevention experiment

[0081] Experimental equipment and sample preparation:

[0082] Prepare an acoustic tester and a noise generator, and make five test pieces of 500 mm×500 mm×50 mm in size for each embodiment. After curing, install the test pieces in a special test box with sound insulation to form a test area similar to a road surface.

[0083] Experimental process:

[0084] A noise generator is used outside the test box to generate stable noise (such as white noise with a frequency range of 50-2000 Hz and a sound pressure level of 80 dB), and the probe of the acoustic tester is placed at a certain height (such as 1 m) above the surface of the test piece to measure the sound pressure level of the noise after it is transmitted through the test piece. Each test piece is tested 3 times, and the average value is taken to calculate the noise reduction value of each embodiment test piece (noise reduction value = initial noise sound pressure level - noise sound pressure level after passing through the test piece)

[0085] Experimental conclusion:

[0086] Embodiment 1: The noise reduction value is about 3-5dB. Its structure is not specially designed for sound absorption. Its main function is anti-slip and its ability to absorb noise is limited.

[0087] Embodiment 2: The noise reduction value is about 5-8dB. The permeable surface layer has a certain pore structure and has a certain absorption effect on noise, but it is not as good as embodiment 3.

[0088] Embodiment 3: The noise reduction value is about 10-15dB. The combination of rubber particles and sound-absorbing materials in the base layer and the surface layer makes the road have a significant absorption effect on noise and has the best anti-noise performance.

[0089] Example 4: The noise reduction value is about 5-8dB. The main function is not sound absorption. Photocatalytic self-cleaning concrete and other materials have average noise absorption capacity while ensuring self-cleaning and anti-slip functions.

[0090]

[0091]

[0092] 4. Self-cleaning experiment

[0093] Experimental equipment and sample preparation:

[0094] Prepare an artificial rainfall simulation device, a pollution simulation agent (mixed with dust, oil, etc. in a certain proportion), and a gloss meter. Prepare five test pieces of 300 mm × 300 mm × 30 mm in size for each embodiment, and evenly apply the pollution simulation agent on the surface of the test piece after curing to simulate the situation of road pollution.

[0095] Experimental process:

[0096] Place the specimens coated with the pollution simulant under an artificial rainfall simulation device, set the rainfall intensity (such as 5mm / min) and rainfall time (such as 30min) to simulate the natural rainfall cleaning process. After the rainfall is over, use a gloss meter to measure the glossiness of the specimen surface. The higher the glossiness, the cleaner the surface. Measure 3 different positions on each specimen and take the average value as the cleanliness index. Compare the glossiness of the specimen after being contaminated before the experiment, and calculate the cleanliness improvement rate (cleanliness improvement rate = (glossiness after cleaning - glossiness after pollution) ÷ glossiness after pollution × 100%)

[0097] Experimental conclusion:

[0098] Embodiment 1: The cleaning degree is improved by about 30%-40%. There is no special self-cleaning material. It mainly relies on natural rainfall to flush, and the cleaning effect is limited.

[0099] Embodiment 2: The cleanliness improvement rate is about 40%-50%. Rainwater can carry away some pollutants through the permeable surface layer, but there is no special self-cleaning mechanism, and the effect is not as good as that of embodiment 4.

[0100] Example 3: The cleanliness improvement rate is about 30%-40%. Its function focus is not on self-cleaning. The porous asphalt concrete and other materials have weak ability to decompose and remove pollutants.

[0101] Example 4: The cleanliness improvement rate is about 60%-70%. The photocatalytic self-cleaning concrete can effectively decompose organic matter under sunlight. The nano-titanium dioxide coating further enhances the self-cleaning effect and has the best self-cleaning performance.
