Problems solved by technology

However, due to the large void ratio of the drainage pavement, the contact between the binder and the aggregate is smaller, so higher viscosity asphalt is required, but the mixing temperature of high viscosity asphalt is high, but if the temperature of colored asphalt is too high, it will turn black, which is not conducive to construction

Abstract

The invention belongs to the technical field of highway construction, and particularly relates to a functional drainage pavement and a preparation method thereof, and a pavement paving material comprises the following components: epoxy asphalt, polyester fibers, a solubilizer, an inorganic pigment, open graded broken stone aggregate and mineral powder. According to the functional drainage pavementprovided by the invention, the mixing temperature is reduced in the construction process, the mixing energy consumption and the mechanical energy consumption are reduced accordingly, meanwhile, the production energy consumption of an epoxy asphalt mixture can be reduced, the aging is reduced, the pavement performance is improved, and due to warm mixing, the construction season is prolonged, and the flexibility of pavement construction is improved.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a functional drainage pavement and a preparation method thereof. Background technique [0002] my country's road construction is developing rapidly, but the construction and operation of roads will inevitably bring a certain degree of environmental disturbance and damage, and the problem of urban water drainage is also gradually serious. The construction of "sponge city" advocated by the state has pointed out the direction for the management of urban rainwater resources. Sponge roads are an important part of the infrastructure construction of sponge cities. As the infrastructure of the city, the road surface drainage performance is particularly important. Cities in my country have successively carried out a number of sponge city construction pilot projects. For the construction of sponge cities, colored asphalt drainage pavement plays an important role. It has dual ad...
