Abstract

The invention discloses an asphalt mixed material. The asphalt mixed material is characterized by comprising an asphalt mixture and a reinforcing skeleton, wherein the reinforcing skeleton is a grid-shaped skeleton prepared from basalt fiber composite reinforcement, and the asphalt mixture includes 29-45 parts of asphalt, 15-45 parts of mortar, 35-60 parts of continuous basalt fibers, and 7-15 parts of carbon powder. The asphalt mixed material provided by the invention has good road surface flatness, does not leave ruts, and eliminates potential safety hazard brought by the ruts.

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...
