Anti-pollution household garbage incinerator slag asphalt pavement structure

Abstract

The invention discloses an anti-pollution household garbage incinerator slag asphalt pavement structure. The structure comprises an asphalt surface layer (1), an upper base layer (2), a lower base layer (4) and a roadbed (6), wherein the asphalt surface layer (1), the upper base layer (2), the lower base layer (4) and the roadbed (6) form the pavement structure from top to bottom. An upper base layer geomembrane wrapping layer (3) is wrapped around the upper base layer (2), a lower base layer geomembrane wrapping layer (5) is wrapped around the lower base layer (4), a roadbed geomembrane wrapping layer (7) is wrapped around the roadbed (6), and the upper base layer (2), the lower base layer (4) and the roadbed (6) are isolated from one another and completely isolated from the external environment. According to the structure, external moisture can be prevented from permeating into the pavement structure, and pollution substances such as heavy metals and compounds thereof in the pavementstructure can also be prevented from migrating into the environment along with water, so that the structure is environment-friendly.

Description

Technical field

[0001] The invention relates to a pavement structure, in particular to an anti-pollution domestic garbage incinerator slag asphalt pavement structure. Background technique

[0002] In recent years, with the ever-increasing urban population and the continuous expansion of urban scale in my country, the amount of urban domestic waste generated has been increasing day by day, and the environmental and social problems brought by it have become more prominent. Domestic waste can be treated by incineration to achieve effective reduction, but incinerator slag still needs special treatment. Resource utilization is a sustainable treatment method for domestic waste incinerator slag, which is environmentally friendly and can save resources. It is the current mainstream research direction. In terms of road construction, material consumption is large, and demand is high. The exploitation of natural aggregates has great damage to the environment and is unsustainable. The util...
