Abstract

The invention discloses a highway drainage asphalt pavement construction process, which comprises the following steps: (1) preparing an asphalt mixture and a mixed aggregate; (2) mixing up according to a certain ratio: uniformly mixing the asphalt mixture and the mixed aggregate in a weight ratio of 94-96:4-6; (3) paving a road surface: paving the above mixed materials obtained in the step (2) on a road surface in the full-width manner, and rolling the mixed materials. Compared with the prior art, the above process is simple and low in manufacturing cost. The void ratio of the prepared drainage asphalt is about 20%, so that a water channel network is formed inside a surface layer thereof. The rainwater, which falls on the road surface, can be discharged out of the road surface through a flow path inside the road. Therefore, no water film or runoff is formed on the road surface. Meanwhile, the prepared road surface is noise-reduction, slip-resistant and long in service life.

Description

technical field [0001] The invention belongs to the technical field of road construction, and in particular relates to a drainage type asphalt pavement construction technology for expressways. 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, preventin...
