Problems solved by technology

[0002] With the development of urban and rural roads, more and more asphalt drainage pavements have appeared. Although the current asphalt drainage pavement has many advantages, it also has some shortcomings. Higher, a greater torque is formed between the tire and the road surface, especially in high temperature seasons, it is easy to cause flying, resulting in damage to the road surface and reducing the service life

Embodiment Construction

[0011] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0012] The invention relates to a construction method for drainage asphalt concrete pavement. The method is as follows: on the basis of the existing construction method, the porosity is reduced by adjusting the amount of each material; The dosage is to improve the adhesion between asphalt and aggregate.

[0013] Specifically, the specific methods for adjusting the amount of each material are: increasing the amount of fine aggregate while reducing the amount of coarse aggregate; increasing the amount of asphalt; increasing the amount of TPS. The modified asphalt is SBS (I-D) modified asphalt. And increase the dosage of anti-stripping agent from 0.2% to 0.4% of th...

Abstract

The invention provides a construction method of a drainage asphalt concrete pavement, which comprises the following steps: on the basis of the existing construction method, regulating the consumptionof each material to reduce the porosity, adopting modified asphalt to improve the high-temperature stability, and improving the adhesion between asphalt and an aggregate by improving the mixing amountof an anti-stripping agent. According to the invention, the two main indexes of the existing road communication void ratio and the water permeability coefficient are effectively improved, the performance requirements of the drainage asphalt pavement are ensured to be met, meanwhile, the phenomena of flying and damage do not occur in the drainage asphalt constructed by the method in a long time period, and the durability of the road is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of pavement construction, and in particular relates to a construction method of drainage asphalt concrete pavement. Background technique [0002] With the development of urban and rural roads, more and more asphalt drainage pavements have appeared. Although the current asphalt drainage pavement has many advantages, it also has some shortcomings. If the tire is too high, a large torsion force will be formed between the tire and the road surface. Especially in the high temperature season, it is easy to cause flying, resulting in damage to the road surface and reducing the service life. [0003] Therefore, to develop a construction method that can effectively improve the quality of drainage asphalt pavement in view of the above problems is a difficult problem that those skilled in the art need to solve urgently. Contents of the invention [0004] In order to solve the above problems, the invention discloses ...
