Description

Technical Field

[0001] The utility model relates to the technical field of asphalt pavement paving, and particularly relates to a noise-reducing asphalt pavement paving structure. Background Technique

[0002] An asphalt pavement is formed by paving and rolling asphalt concrete to form various types of road surfaces. Asphalt concrete is a mixture formed by fully mixing asphalt materials with a certain viscosity and appropriate dosage and mineral aggregates with a certain gradation. As asphalt pavement material, asphalt concrete has to bear the repeated action of vehicle loads during use and the long-term influence of environmental factors. Therefore, while having a certain bearing capacity, asphalt concrete must also have good durability against the action of natural factors. That is to say, it should be able to exhibit characteristics such as sufficient stability under high-temperature environments, crack resistance under low-temperature conditions, good water stability, long-lasting anti-aging property, and anti-skid property conducive to safety, so as to ensure the good service function of the asphalt pavement.

[0003] During the laying process of the existing asphalt pavement, it is necessary to lay a cushion layer, a subbase course, a base course, and a surface course in sequence, with a long construction period and low construction efficiency. During the construction process, it will block the surrounding road surface, thereby causing vehicles and pedestrians to be unable to pass.

[0004] Therefore, it is very necessary to invent a noise-reducing asphalt pavement paving structure to solve the above problems. Content of the Utility Model

[0011] By adopting the above technical solution, the road surface structure is erected on the upper side of the concrete foundation stones, and the insertion rods are inserted into the insertion holes to fix the road surface module.

[0012] Optionally, metal clamping strips are fixedly connected to the upper surface of the concrete base layer, and the coarse asphalt layer is laid on the upper surface of the concrete base layer inside the metal clamping strips.

[0013] Optionally, the fine asphalt layer is laid on the upper surface of the coarse asphalt layer, and the noise reduction road surface layer is laid on the upper surface of the fine asphalt layer.

[0017] By adopting the above technical solution, the water permeable holes are used to quickly penetrate the water collected on the road surface downward and introduce the water flow into the drainage pipes on both sides.

[0018] Optionally, roadbed stones are laid on the left and right sides of the rammed plain soil layer, drainage holes are formed on the surface of the roadbed stones, and the drainage holes communicate with the water inlet holes.

The crushed stone cushion layer 2 is paved on the upper side of the plain soil compaction layer 11. The concrete foundation stones 21 are arranged at intervals on the upper side of the crushed stone cushion layer 2. The crushed stone filling layer 23 is paved between two groups of crushed stone cushion layers 2. A plurality of insertion holes 22 are formed on the surface of the concrete foundation stone 21. A plurality of insertion rods 25 are fixedly connected to the lower surface of the concrete base layer 24. The insertion rods 25 are inserted into the interior of the insertion holes 22. A metal clamping strip 26 is fixedly connected to the upper surface of the concrete base layer 24. The coarse asphalt layer 27 is paved on the upper surface of the concrete base layer 24 inside the metal clamping strip 26. The fine asphalt layer 28 is paved on the upper surface of the coarse asphalt layer 27. The noise-reducing road surface layer 29 is paved on the upper surface of the fine asphalt layer 28.

[0032] Among them, the concrete base layer 24, the coarse asphalt layer 27, the fine asphalt layer 28 and the noise-reducing road surface layer 29 are integrated into a road surface module through a template. At the same time, water permeable holes 210 are reserved inside the road surface module. The insertion rods 25 are fixedly connected to the lower side of the concrete base layer 24. After the road surface structure is prefabricated, marking lines are pre-brushed on the surface of the noise-reducing road surface layer 29. During the process of road surface paving, first, a foundation pit is excavated, the plain soil at the bottom of the foundation pit is compacted, then the crushed stone cushion layer 2 is paved on its surface, then the concrete foundation stones 21 are arranged at intervals on the upper side of the crushed stone cushion layer 2, the crushed stone filling layer 23 is paved between the concrete foundation stones 21, and a plurality of concrete foundation stones 21 are fixed.
