Abstract

The invention discloses a preparation process for an asphalt mixture pavement. The preparation process is characterized by comprising the following process steps: 1, preparing staple basalt fibers; 2, preparing used tire grains; 3, preparing broken stones; 4, heating asphalt; 5, preparing mineral powder; 6, performing mixing to obtain an asphalt mixture; 7, preparing the asphalt mixture pavement. According to the preparation process, the staple basalt fibers are added into the asphalt mixture, so that the strength, high temperature resistance and low temperature resistance of the asphalt mixture are improved, the prepared pavement can be prevented from being damaged by the snow-ice weather in the north and exposure to the sun in the south, and is high in flatness, no wheel tracks can be formed, and potential safety hazards caused by the wheel 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...
