Abstract

The invention discloses environment-friendly asphalt capable of actively suppressing rising dust on a road surface. The environment-friendly asphalt is a composite material and comprises matrix asphalt and an environment-friendly asphalt additive capable of actively suppressing rising dust on the road surface. The environment-friendly asphalt additive capable of actively suppressing rising dust onthe road surface comprises a component for actively suppressing rising dust on the road surface and a tackfying and plasticizing component, wherein the component for actively suppressing rising duston the road surface comprises one or more selected from a group consisting of zeolite powder, montmorillonite powder, sepiolite powder and nest-like ore powder, and the tackfying and plasticizing component comprises one or more selected from a group consisting of polyester fibers, glass fibers and rubber fibers. The environment-friendly asphalt capable of actively suppressing rising dust on the road surface in the invention has water absorption and moisture retention properties, and is simple to prepare, low in production cost and capable of suppressing rising dust on a road without any influence on the other properties of the asphalt.

Description

technical field [0001] The invention belongs to the technical field of asphalt roads and environmental engineering, and relates to asphalt and a preparation method thereof, in particular to an environment-friendly asphalt for actively suppressing dust on road surfaces and a preparation method thereof. Background technique [0002] In recent years, fog and haze have occurred frequently in my country's Beijing-Tianjin-Hebei region and North China. Many cities will encounter large-scale persistent fog and haze in autumn and winter, which will seriously affect people's normal travel and daily life. The problem of air pollution has attracted widespread attention at home and abroad. Studies have shown that some harmful and toxic substances in the atmosphere can cause irreversible damage to human physiological functions and seriously affect people's physical and mental health. Therefore, it is necessary to control smog to protect the environment. imminent. In some large urban envi...
