Embodiment 1

[0033] Example 1: Prepare 3000 g of the highly elastic colored anti-skid wear layer of the present invention, and test the road performance of the material.

[0034]

[0035] The base asphalt is melted at 140°C and added to the reaction kettle, then the compatibilizer, rheology agent, anti-ultraviolet aging agent and curing agent are added in sequence, the temperature is controlled at 90±5°C, and stirred for 2 to 3 hours to form the B component, and the A Components and B components are mixed evenly in proportion at room temperature, and then fine stones are added and stirred evenly. According to the test requirements, after forming various test specimens, sprinkle colored wear-resistant glass beads. The test results are as follows:

[0036]

[0037] It can be seen from the test results that the various performances of the colored anti-skid wear layer material used in Example 1 can meet the technical requirements, and the performance is good.

Embodiment 2

[0038] Example 2: Prepare 3000 g of the highly elastic colored anti-skid and wear layer of the present invention, and test the road performance of the material.

[0039]

[0040] The base asphalt is melted at 140°C and added to the reaction kettle, then the compatibilizer, rheology agent, anti-ultraviolet aging agent and curing agent are added in sequence, the temperature is controlled at 90±5°C, and stirred for 2 to 3 hours to form the B component, and the A Component and B component are mixed evenly in proportion at room temperature, then add fine stones and stir evenly. According to the test requirements, after forming various test specimens, sprinkle colored wear-resistant granite stone materials, the test results are as follows:

[0041]

[0042] It can be seen from the test results that the various properties of the colored anti-skid wearing layer material used in Example 2 can meet the technical requirements, and the performance is good.

Abstract

The invention relates to a road surface structure of a road project. The mass composition of the invention is that: 0-20 parts of polyurethane,0-20 parts of alkyd, 0-20 parts of methyl-methacrylate resin, 20-50 parts of substrate pitch,10-20 parts of compatiblizing agent, 2-5 parts of rheological agent, 1-5 parts of ultraviolet aging resisting agent, 10-30 parts of curing agent, 10-20 parts of gravel and 50-200 parts of colorful wear-resistant rubble. The invention is characterized by simple formula, easy manufacture, strong adhesive capacity, good antiskid capacity, and good low-temperature property and does not crack in cold areas of the northern. The structure can be applied to laying the surface of the tunnel (especially the tunnel surface 200-300m away from the entrance and exit of the tunnel), bridge, airport pavement, bending section of the senior road and the repair of the used cement concrete pavement.

Description

technical field [0001] The invention relates to a road engineering pavement structure, in particular to a highly elastic colored anti-skid wear layer. Background technique [0002] With the increasing development of road traffic, the performance of vehicles and the level of roads are gradually improved, and the speed of vehicles is also gradually accelerated. To reduce personal injury and property loss caused by accidents, pave a layer of anti-slip surface with good anti-skid performance on the road surface of road accident-prone areas such as bridge decks, tunnels, downhill roads, sharp turns, traffic lights and road tolls The road surface or speed bump can undoubtedly improve the driving safety factor. [0003] But the current wear layer mainly includes road spike speed bumps, hump speed bumps, cement platform speed bumps, thermoplastic vibration speed bumps, road concave groove speed bumps, etc. As a traffic facility to ensure the safety of pedestrians, the basic princi...
