Abstract

The invention discloses a construction process of a highway drainage asphalt pavement, comprising the steps of (1) preparing asphalt mix and blended aggregate; (2) blending at a ratio, to be specific, mixing well the asphalt mix and the blended aggregate at the weight ratio of (94-96):(4-6); (3) paving the pavement, to be specific, covering a whole pavement with the mixture of step (2), and rolling to the paved pavement. Compared with the prior art, the construction process is simple and is low in manufacture cost; drainage asphalt that is produced is about 20% in porosity such that a waterway network is formed in the pavement layer, rainwater falling at the pavement layer may flow through gaps in a highway out of the pavement, water film and runoffs are not formed on the surface, and the pavement is noise-reducing and antiskid and has long service life.

Description

technical field [0001] The invention belongs to the technical field of road construction, and in particular relates to a construction technique for highway drainage asphalt pavement. Background technique [0002] With the rapid development of economy and society, people's demand for travel quality has been continuously upgraded, and the concept of "environmental friendliness" has become increasingly prominent in transportation construction. In the field of road engineering, how to improve the use function of the road surface and how to provide the society with high safety, more comfortable and more environmentally friendly road surface characteristics has become a new goal pursued by my country's transportation department in the new era. [0003] Looking at the frontiers of technology at home and abroad, the drainage asphalt pavement pavement with large voids has outstanding advantages such as high anti-skid performance, low noise, suppressing water mist, preventing water dr...
