Problems solved by technology

[0003] At present, there are many kinds of anti-rutting agents in the domestic and foreign markets, and the production process and anti-rutting effect are also uneven, but their production is accompanied by gases and liquids that are harmful to the environment.
Although foreign anti-rutting agents have excellent effects, it is not realistic to apply them in the domestic market, mainly because of the high price
[0004] Modified asphalt (SBS modified asphalt or PE modified asphalt) is also widely used in China to improve the anti-rutting performance of asphalt mixture. This method mainly uses SBS or PE as an additive, and uses a colloid mill to disperse the additive at high speed. In matrix asphalt, SBS or PE modified asphalt is formed. This method needs to go through processes such as swelling, dispersion, shearing and development. Due to the poor compatibility of SBS and PE with asphalt, during transportation and storage, modifiers and matrix Asphalt is prone to segregation, and this modified asphalt needs to be heated many times, which will easily cause energy consumption and asphalt aging

Abstract

The invention provides a direct-vat type environment-friendly anti-rutting agent. The anti-rutting agent is prepared from materials shown in the description. The direct-vat type environment-friendly anti-rutting agent is ellipsoidal particles and can be directly put into an asphalt and concrete stirring machine, stirring and contact of the anti-rutting agent and asphalt are more sufficient, and dispersion is more sufficient. Product storage, transportation and use are very convenient, and product quality completely meets the requirement of heavy-load pavements.

Description

technical field [0001] The invention relates to the technical field of additives in road surface mixtures, more specifically, to a direct-injection environment-friendly anti-rutting agent for heavy-duty road surfaces of traffic roads and a production device and method thereof. Background technique [0002] With the rapid growth of the national economy, my country's highway construction has developed rapidly, and the mileage of traffic has ranked second in the world. Most of the built highways use asphalt pavement. After the completion and opening to traffic, with the increasing climate, traffic volume and overloading, the road surface has different degrees of rutting. If no effective measures are taken to treat it, not only the road surface will The service performance attenuation is serious, which affects the speed, comfort, smoothness and safety of driving, and will cause structural damage to the road, shorten the service life of the road surface, and cause greater economi...
