Bituminous mixture

Abstract

The invention discloses bituminous mixture. The bituminous mixture is characterized in that the bituminous mixture comprises pitch, macadam, mortar, continuous basalt fibers and mineral powders. The bituminous mixture comprises, by weight, 18-22 parts of pitch, 12-34 parts of mortar, 18-42 parts of continuous basalt fibers and 5-16 parts of mineral powders. The continuous basalt fibers are added into the bituminous mixture to improve the strength, the high-temperature-resisting performance and the low-temperature resisting performance of the bituminous mixture, the road surface manufactured with the bituminous mixture cannot be destroyed no matter in snow-ice weather in northern area or under the solarization in southern area, the surface evenness is good, a track also cannot be left, and a potential safety hazard caused by the track is removed.

Description

technical field [0001] The invention belongs to the field of road and bridge construction, in particular to an asphalt mixture used as a highway pavement. 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 aggregat...

Problems solved by technology

[0043] In order to overcome the defects of poor high temperature resistance and low temperature resistance of the above-mentioned various asphalt mixtures, the present invention provides an asphalt mixture, which is added with continuous basalt fiber to enhance the strength and resistance of the asphalt mixture. High temperature and low temperature resistance performance, not only can be exposed to the sun for a long time, but also can be used in ice and snow weather, the scope of application is light, and the service life is long
