Environment-friendly asphalt mixture capable of actively inhibiting flying dust on road surface and preparation method of environment-friendly asphalt mixture

Abstract

The invention discloses an environment-friendly asphalt mixture capable of actively inhibiting flying dust on a road surface. The environment-friendly asphalt mixture comprises aggregates and environment-friendly asphalt capable of actively inhibiting flying dust on the road surface; the environment-friendly asphalt capable of actively inhibiting flying dust on the road surface comprises asphalt and an environment-friendly asphalt additive capable of actively inhibiting flying dust on the road surface; the environment-friendly asphalt additive capable of actively inhibiting flying dust on theroad surface comprises a component for actively inhibiting dust and a tackifying and plasticizing component; the component for actively inhibiting dust comprises one or more of zeolite powder, montmorillonite powder, sepiolite powder and nest-like ore powder; and the tackifying and plasticizing component comprises one or more of polyester fibers, glass fibers and rubber fibers. The environment-friendly asphalt mixture capable of actively inhibiting flying dust on the road surface, disclosed by the invention, is free of pollution to surrounding environments and can actively adsorb water in theair to form a water film on the road surface to increase the weight of the dust, so that the double effects of actively inhibiting flying dust on the road surface and saving water sprayed for inhibiting dust on a road.

Description

technical field [0001] The invention belongs to the technical field of asphalt roads and environmental engineering, and relates to an asphalt mixture and a preparation method thereof, in particular to an environment-friendly asphalt mixture for actively suppressing road surface dust 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 l...

Problems solved by technology

[0007] In order to solve the problems existing in the prior art, the present invention provides an environmentally friendly asphalt mixture that actively suppresses road surface dust, and its purpose is to solve the existing road dust problem and reduce unnecessary waste of water resources. The dust-suppressing environment-friendly asphalt additive is directly added to the base asphalt to form an active dust-suppressing road-surface environment-friendly asphalt, and then the active-suppressing road-surface dust-sustaining environment-friendly asphalt is added to mineral aggregates to form an active road surface dust-suppressing environment-friendly asphalt The mixture, the paved road is paved with the environmentally friendly asphalt mixture that actively suppresses the dust on the road surface, has no pollution to the surrounding environment, and enables the road to absorb moisture in the air, increasing the dust density on the road surface, so that the dust on the road surface It is not easy to be taken away by passing vehicles to achieve the purpose of dust suppression
