Abstract

The invention discloses an asphalt pavement with a composite structure. Theasphalt pavement sequentially comprises a roadbed layer, a first waterproof layer, a stress release layer, a sealing layer, a second waterproof layer and a cement-asphalt composite structure layer from bottom to top, the stress release layer adopts concrete pillows as constraint boundaries, and buffer broken stones are paved between the concrete pillows; the cement-asphalt composite structure layer is mainly composed of a cement concrete layer and an asphalt mixture layer embedded and extruded into the cement concrete layer, and a reinforcing mesh is laid in the bottom of the cement concrete layer. The pavement provided by the embodiment of the invention is formed by compounding a plurality of structural layers with different material types and mechanical properties, the advantages of a rigid pavement and a flexible pavement can be integrated, and the occurrence of pavement diseases is reduced in a low-cost manner.

Description

technical field [0001] The application relates to the field of highway and urban road engineering, in particular to a composite structure asphalt pavement. Background technique [0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed with mineral materials, which has the advantages of comfortable driving and low noise. Asphalt binder can improve the ability of paving aggregates to resist damage to the road surface caused by driving and natural factors, making the road surface smooth, less dusty, impermeable and durable. According to the "Code for Design of Highway Asphalt Pavement", the structural layer of asphalt pavement consists of three parts: surface layer, base layer and subbase layer. Most of the high-grade pavement in my country adopts semi-rigid base asphalt pavement structure. [0003] Asphalt pavement structure belongs to flexible pavement structure. Asphalt mixture is a mixture formed by mixing gravel with asphalt, ...
