[0031] A road paving structure for municipal engineering, including a base layer 1, a buffer layer 2 located above the base layer 1, and a road surface layer 3 laid above the buffer layer 2. A plurality of anti-slip bumps 4 are provided at the upper end of the road surface layer 3. Both the middle of the left end and the middle of the right end of the road surface layer 3 are fixedly connected with gutter blocks 5. Grooves 6 are opened in both gutter blocks 5. Drainage pipes 7 are provided at the bottoms of both gutter blocks 5. A waterproof geotextile layer 8 is provided between the base layer 1 and the buffer layer 2. Fixed blocks 9 are fixedly connected to the four corners of the upper end and the four corners of the lower end of the waterproof geotextile layer 8.
[0032] Through the above solution: The base layer 1 is composed of compacted earth and stone materials, providing a stable support foundation for the entire road structure and bearing the pressure from the upper layers. The buffer layer 2 is made of a mixture of rubber particles and asphalt and is located above the base layer 1. When a vehicle travels on the road surface, the buffer layer 2 can absorb the vibration and impact force generated by the vehicle, reducing the damage to the base layer 1 and playing a buffer and protective role. The road surface layer 3 is laid above the buffer layer 2. The anti-slip bumps 4 provided at its upper end increase the friction between the tire and the road surface when the vehicle is traveling, preventing the vehicle from skidding and improving driving safety. The gutter blocks 5 are fixedly connected to the middle of the left and right ends of the road surface layer 3. When there is water accumulation on the road surface, the water flows into the grooves 6 opened in the gutter blocks 5. The drainage pipes 7, located at the bottoms of the gutter blocks 5, are connected to the municipal drainage system. The accumulated water in the grooves 6 is discharged in time through the drainage pipes 7, avoiding the influence of road surface water accumulation on traffic and damage to the road structure. The waterproof geotextile layer 8 is provided between the base layer 1 and the buffer layer 2 and is fixed by the fixed blocks 9 at the four corners of the upper end and the four corners of the lower end. Its function is to prevent the upward penetration of groundwater and protect the road structure from the erosion of groundwater.
[0033] In this embodiment, the anti-slip bumps 4 are hemispherical structures with a height between 3 and 5 millimeters, and the distance between adjacent anti-slip bumps 4 is between 20 and 30 millimeters; the gutter blocks 5 are made of high-strength concrete materials, with a length between 0.5 and 1 meter, a width between 0.3 and 0.5 meter, and a height between 0.4 and 0.6 meter; the fixing blocks 9 are made of metal and are fixedly connected to the base layer 1 and the buffer layer 2 respectively through bolts; the buffer layer 2 is a mixed layer of rubber particles and asphalt, with a thickness between 5 and 10 centimeters; the waterproof geotextile layer 8 is bonded to the base layer 1 and the buffer layer 2 using an adhesive.
[0034] Through the above solution: the hemispherical anti-slip bumps 4 increase the friction force, and the height and distance are within a specific range to prevent the vehicle from skidding; the gutter blocks 5 are made of high-strength concrete, and the specific size collects the road surface water and guides it into the drainage pipe 7; the metal fixing blocks 9 connect the base layer 1 and the buffer layer 2 through bolts to fix the waterproof geotextile layer 8; the buffer layer 2 is a mixture of rubber particles and asphalt, with a moderate thickness, which absorbs the vibration and impact to protect the base layer 1; the waterproof geotextile layer 8 is bonded to the base layer 1 and the buffer layer 2 using an adhesive to prevent the infiltration of groundwater.
[0035] It should be noted that the present utility model is a road paving structure for municipal engineering. During the use process, first, the construction of the base layer 1 is carried out, and the compacted soil and stone materials are laid and compacted according to the design requirements to provide a stable support foundation for the entire road structure. Then, the waterproof geotextile layer 8 is laid on the base layer 1 and is preliminarily fixed to the base layer 1 through the fixing blocks 9 and bolts. The waterproof geotextile layer 8 can effectively prevent the upward infiltration of groundwater and protect the road structure from the erosion of groundwater. Above the waterproof geotextile layer 8, the buffer layer 2 is laid. The buffer layer 2 is a mixture of rubber particles and asphalt, which can absorb the vibration and impact generated by vehicle driving, reduce the damage to the base layer 1, and improve the stability of the road. Then, the road surface layer 3 is laid above the buffer layer 2. The road surface layer 3 is laid with modified asphalt concrete materials, and several hemispherical anti-slip bumps 4 are arranged at its upper end to enhance the anti-slip performance of the road surface and improve the driving safety. The gutter blocks 5 are fixedly installed in the middle of the left end and the middle of the right end of the road surface layer 3. The gutter blocks 5 are made of high-strength concrete materials. Grooves 6 are provided in the gutter blocks 5. When there is water on the road surface, the water flows into the grooves 6. Finally, the drainage pipe 7 provided at the bottom of the gutter blocks 5 drains the water in the grooves 6 in time. The drainage pipe 7 is connected to the municipal drainage system to ensure that the rainwater can be discharged smoothly, avoiding the influence of road surface water on traffic and accelerating the damage of the road.
