Durable type asphalt pavement structure

Abstract

The invention discloses a durable type asphalt pavement structure which comprises a base layer, a mixed layer, a cement concrete layer and an asphalt layer, wherein the base layer is laid on the ground, a water draining pipeline is arranged in the horizontal direction in the base layer, the mixed layer is laid on the upper surface of the base layer, the mixed layer is formed by stone and gravel, the gravel is laid among the stone, the laid thickness of the gravel is a half of the height of the stone, the cement concrete layer is laid on the upper surface of the mixed layer, two or more protruded long stripes are arranged on the surface of the cement concrete layer, the same steps are arranged on the two sides of the protruded long stripes, the protruded long stripes are arranged in a criss-cross mode to form a grid structure, and the asphalt layer is laid in grids formed by the protruded long stripes. The asphalt pavement structure disclosed by the invention has a self-repair function,so that the service life of the asphalt pavement is prolonged, maintenance times and maintenance cost are reduced; the structure further has a water drainage function.

Description

technical field [0001] The invention relates to the field of machine pavements, in particular to a durable asphalt pavement structure. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials infiltrated in mineral materials. With the rapid development of economy, more and more vehicles are driving on asphalt pavement, especially large trucks or overloaded vehicles. During emergency braking, since the asphalt pavement is semi-rigid, sudden braking will cause partial deviation of the asphalt pavement, causing part of the asphalt to sag and part to protrude, reducing the service life of the asphalt pavement. Contents of the invention [0003] The purpose of the present invention is to provide a durable asphalt pavement structure to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a dura...
