Anti-skid rainproof mist-resistant asphalt pavement material and preparation method thereof

Abstract

The invention discloses an anti-skid rainproof mist-resistant asphalt pavement material and a preparation method thereof. The asphalt pavement material is composed of the following components in parts by weight: 64 to 79 parts of asphalt macadam, 12 to 19 parts of cement, 42 to 76 parts of mineral powder, 12 to 35 parts of limestone, 1 to 10 parts of ceramsite, 15 to 19 parts of medium sand, 6 to 18 parts of emulsifier, 10 to 14 parts of smoke suppressor, 6 to 9 parts of curing agent, 1 to 10 parts of filling material, and 100 to 150 parts of water; wherein the weight ratio of mineral powder: limestone: ceramsite is 1:(0.1-0.8):(0.02-0.2); the weight ratio of emulsifier: curing agent is 1:1-3:1; the smoke suppressor is silica powder, and the particle size of the medium sand is 0.25 to 0.4 mm. Through the abovementioned technical scheme, the anti-skin, rainproof, and mist-resistant performance of the pavement is enhanced, the safety hazard is reduced, moreover, the material has the advantages of excellent compressive strength, good caking property, and strong wear resistant performance, and the service life of pavement is prolonged.

Description

technical field [0001] The invention belongs to the technical field of pavement materials, in particular to an anti-sliding rain fog asphalt pavement material. Background technique [0002] Today, the construction of highways, national highways, provincial highways, county roads, township roads and village roads has increased on a large scale across the country, bringing great convenience to people's life and work. Asphalt concrete pavement has the advantages of convenient construction and strong practicability in road construction, and has been widely used as a construction material for various roads. [0003] Asphalt concrete pavement is constantly subjected to the friction, impact and rolling of vehicle tires. Traditional asphalt concrete has poor anti-skid performance. Especially in rainy days, rainwater will accumulate on the road surface, forming a water film and discontinuous water, which makes tires and Inadequate contact with the road surface leads to a decline in ...

Problems solved by technology

[0003] Asphalt concrete pavement is constantly subjected to the friction, impact and rolling of vehicle tires. Traditional asphalt concrete has poor anti-skid performance. Especially in rainy days, rainwater will accumulate on the road surface, forming a water film and discontinuous water, which makes tires and Inadequate contact with the road surface leads to a decline in the anti-skid performance of the road surface, and when the wheels are running at high speed, rain and fog are easily generated between the wheels and the road surface, which affects the driving line of sight of subsequent vehicles and increases driving safety hazards
