Problems solved by technology

[0005] The invention provides a gravel asphalt concrete pavement of equal thickness particle size and its construction method, which solves the problem that the asphalt pavement is prone to rutting. The thickness of the road surface forms a skeleton, and the asphalt concrete mixture is filled between the skeletons

Embodiment 1

[0025] Make asphalt concrete pavement with 6cm thick and equal particle size crushed stone.

[0026] In the specific implementation, it is first necessary to carry out the material design and test of equal-thickness gravel asphalt concrete pavement, including the following steps:

[0027] 1. Selection and dosage of asphalt for spreading. Choose 90 for the first layer and the second layer of sprinkling asphalt # Road petroleum asphalt, the dosage is 0.4kg / m 2 ;

[0028] 2. The selection and dosage of spreading gravel. The maximum particle size of spreading gravel is equal to the thickness of the road surface. Limestone gravel is selected for spreading. The particle size is: 55mm3 / 1000m 2 ;

[0029] 3. Mixing ratio design of hot mix asphalt mixture. Design AC-13 type asphalt concrete mixture according to the specifications; AC-13 type asphalt concrete mixture is used to fill the gaps where crushed stones are scattered, and its dosage is equal to the volume of the voids. T...

Abstract

The invention relates to the technical field of road construction and maintenance, particularly relates to an asphalt concrete pavement adopting rubbles with the particle size equal to pavement thickness and a construction method thereof. The asphalt concrete pavement is characterized by being prepared from, by weight, 0.3 kg / m<2>-0.6 kg / m<2> of applied first-layer asphalt, 20 m<3> / 1000 m<2>-40 m<3> / 1000 m<2> of the applied rubbles, 0.3 kg / m<2>-0.6 kg / m<2> of applied second-layer asphalt, and 20 m<3> / 1000 m<2>-40 m<3> / 1000 m<2> of AC-13 type asphalt concrete mixture. The problem that tracks are easily produced on an asphalt pavement is solved, the particle size of the biggest rubbles of aggregate in the asphalt concrete pavement adopting rubbles with the particle size equal to the pavement thickness is equal to the pavement thickness, and a framework is formed and meanwhile is filled with the asphalt concrete mixture.

Description

technical field [0001] The invention relates to the technical field of road construction and maintenance, in particular to a gravel asphalt concrete pavement with equal thickness particle size and a construction method thereof. Background technique [0002] Most of the roads and urban roads that have been built in my country are asphalt roads. Due to the serious overloading of vehicles, large traffic volume, channelized driving, and high temperature weather, rutting has become the most important disease in the early stage of asphalt pavement, such as the climbing section of the expressway, the BRT (Bus Rapid Transit) lane and Rutting is the most likely and serious place on the guide road, etc. According to the data, 80% of the asphalt pavement has rutting in different degrees. It is a stubborn disease among road diseases and has not been solved. [0003] At present, the typical asphalt pavement structure is divided into three types: suspended dense structure, skeleton void ...
