Problems solved by technology

[0004] However, the main feature of drainage asphalt pavement is the large void ratio (18-25%), which makes it more likely to be eroded by water, air, and sunlight. It is relatively low, so it is prone to cracking, causing the internal structure to suffer from rainwater erosion for a long time, resulting in a decrease in the durability of the road surface, so there is still room for improvement

Abstract

The invention relates to a modified asphalt and provides the modified asphalt with high viscosity and high elasticity, in order to solve the problem of reduction of durability of pavement. According to the technical scheme, the modified asphalt with high viscosity and high elasticity contains the following components in parts by weight: 100 parts of asphalt, 10-15 parts of butadiene styrene rubber, 20-40 parts of volcano fiber, 0.5-1.5 parts of cross-linking agent and 5-10 parts of oil. 'Structural asphalt' is formed by adding the volcano fiber; the volcano fiber has excellent heat-insulatingeffect and physical properties, so that viscosity and heat insulation of the modified asphalt are promoted; the modified asphalt is reinforced, so that the asphalt layer is difficult to crack and deform and the service life of the modified asphalt is prolonged.

Description

technical field [0001] The invention relates to a modified asphalt, more specifically, it relates to a modified asphalt with high viscosity and high elasticity. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid with a black surface and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. Pitch can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch. Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural bitumen is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries as well as paving roads. [0003] Orthotropic steel br...
