Problems solved by technology

Thirdly, when rubber particles are added to the asphalt mixture, due to the large elastic deformation capacity of the rubber particles, the embedding effect between the rubber particles and the aggregate is not obvious, and the looseness of the mixture is prone to occur, which affects the durability of the pavement structure.

Abstract

The invention concretely relates to a pavement self icebreaking anti-slip pavement layer mixed material and a preparation method thereof. Passive deicing measures are mechanical snow removal, salt spreading icebreaking and the like, labor and materials are wasted, and in addition, negative influence can be caused on the environment. The active deicing measures are measures of adding rubber particles into asphalt mixed materials and using the deformation of the rubber particles so that the pavement can generate self stress to crush ice and snow under the external load effect, but the requirement on running vehicles is strict, aggregate under the vehicle running load effect is easy to get loose, and the durability is poor. Rubber particles, polyurethane bonding agents, fiber, hydrophobic materials and dryers are proportionally mixed to be prepared into the pavement self icebreaking anti-slip pavement layer mixed material to be paved on the pavement for inhibiting the pavement accumulated snow and ice. The anti-slip performance of the pavement in winter under the low-temperature snowy condition is improved, the running safety of the running vehicles after the pavement icing is ensured, the pavement is simple, and the durability is high.

Description

technical field [0001] The invention belongs to the technical field of traffic and transportation engineering, and in particular relates to a road self-ice-breaking anti-slip pavement mixture and a preparation method thereof. Background technique [0002] When a vehicle is traveling at high speed on an ice-covered road, the probability of a traffic accident will greatly increase. There are two types of road deicing: active and passive. At present, the main measures taken by my country's highway departments to deal with road icing are passive deicing and snow removal measures, such as mechanical snow removal, salt spreading to break ice, etc. These measures not only require a lot of manpower and material resources, but also have negative impacts on the environment. Sprinkling salt to break the ice can also easily cause erosive damage to bridges. The special material added in the present invention is rubber particles. Active measures are to crush waste rubber tires into par...
