Abstract

The invention discloses an asphalt mixture pavement. The asphalt mixture pavement is composed of an asphalt mixture and a reinforcing framework, wherein the reinforcing framework is a latticed framework, the asphalt mixture is prepared from, by weight, 15-22 parts of asphalt, 8-12 parts of gravel, 2-8 parts of waste tire particles, 22-38 parts of basalt fiber staples and 2-6 parts of mineral powder, the reinforcing framework is made from, by weight, 24-38 parts of continuous basalt fiber, 12-22 parts of glass fiber and 14-28 parts of carbon fiber. The basalt fiber staples are added in the asphalt mixture to improve the strength and high temperature and low temperature resisting performance of the asphalt mixture, the asphalt mixture pavement is not damaged both in icy and snowy weather in the north and sun exposure in the south and is good in road surface evenness, no track is also left, and the potential safety hazards brought by tracks are eliminated.

Description

technical field [0001] The invention belongs to the field of road and bridge construction, in particular to an asphalt mixture pavement for laying roads. Background technique [0002] There are asphalt pavement and cement pavement on highways or urban street roads. Asphalt pavement has little friction on tires, but it is softened by heat in hot weather, and ruts are formed after the car is rolled, and asphalt is bonded to the tires. First, it is easy to cause traffic accidents. , but more damage to the tires. However, the cement road has a large friction to the tires, a large wear and tear on the tires, and the cost is relatively high. [0003] Therefore, asphalt mixture is mostly used for the road surface laid now. The existing asphalt mixture can be divided into two categories: petroleum asphalt and coal asphalt according to the different binders used; some countries or regions also use or mix it. Mixed with natural asphalt. According to the different types of aggregate...
