Embodiment 1

[0028] Example 1: A pavement structure of permeable and drainage asphalt pavement, from the top surface of the base, from bottom to top are waterproof adhesive layer 1, high-viscosity modified asphalt concrete PAC-13 lower layer 2, low-volume epoxy asphalt Concrete PAC-10 middle surface layer 3, filter layer 4, high viscosity modified asphalt concrete PAC-5 upper layer 5, heat insulation layer 6.

[0029] Its preparation method comprises the following steps:

[0030] (1) First clean the top surface of the base, and then spread the emulsified asphalt waterproof bonding layer, the spreading amount is 0.5kg / m 2 ~0.6kg / m 2 After the emulsified asphalt is broken, pave the lower layer of high-viscosity modified asphalt concrete PAC-13.

[0031] Among them, the emulsified asphalt is prepared by modifying first and then emulsifying. The emulsifier content is 2.0%, the stabilizer content is 0.1%, and the oil-water ratio is 60:40. The thickness of the lower layer of high-viscosity mo...

Abstract

The invention belongs to the technical field of highway construction, in particular to a permeable and drainage asphalt pavement paving structure. The permeable and drainage asphalt pavement paving structure comprises a waterproof bonding layer, a high-viscosity modified asphalt concrete PAC-13 lower surface layer, a low-dosage epoxy asphalt concrete PAC-10 middle surface layer, a filtering layer,a high-viscosity modified asphalt concrete PAC-5 upper surface layer and a heat insulation layer from bottom to top from the top surface of a base layer. The permeable and drainage asphalt pavement paving structure provided by the invention is high in structural bearing capacity, excellent in permeable and drainage performance and good in noise reduction effect, and in addition, the generation ofa heat island effect can be effectively reduced.

Description

technical field [0001] The invention relates to a road pavement structure and material, in particular to a permeable and drainage asphalt pavement structure. Background technique [0002] Because the common concrete pavement in the city has no water-permeable and air-permeable effect, this also prevents rainwater from penetrating into the ground in time, causing surface plants to fail to survive due to lack of water resources, and the groundwater level is declining year by year; ordinary impermeable concrete pavement cannot be adjusted in time Urban surface temperature and humidity also form the so-called "heat island phenomenon". In order to improve the driving safety of high-grade highways, many studies on the application of permeable and drainage asphalt pavement have been carried out in China. A thin layer of macrovoid, open-graded asphalt mixture is laid over the asphalt pavement surface. In this way, water can be discharged from its porous structure in rainy days, an...
