Abstract

The invention relates to the technical field of asphalt preparation, and discloses high-performance modified asphalt. The high-performance modified asphalt is prepared from the following components in parts by weight: 15-30 parts of auxiliary materials, 10-18 parts of a modifier, 50-100 parts of raw asphalt and 2-25 parts of a solvent. The invention also discloses a manufacturing method of the high-performance modified asphalt. The manufacturing method comprises the following steps: S1, crushing of the modifier: putting the modifier into a crusher for crushing for 10-30 minutes, and then conducting screening with a 200-to-400-mesh sieve to obtain the crushed modifier; and S2, dissolving of the modifier: adding the crushed modifier and a solvent into a mixing tank, and carrying out stirring and mixing to obtain a mixed solution A. By adding the modifier, the viscosity and toughness, the softening point, the low-temperature cracking resistance and the elasticity of the modified asphalt can be effectively improved; and by doping an anti-stripping agent and an anti-aging agent, the use performance of a pavement material can be improved, and the service life of the pavement material can be prolonged.

Description

technical field [0001] The invention relates to the technical field of asphalt preparation, in particular to a high-performance modified asphalt and a manufacturing method thereof. Background technique [0002] Asphalt is the main pavement material used in road engineering at home and abroad. Modern road traffic is characterized by large traffic volume, fast speed and high load capacity. Therefore, the requirements for road surface quality are also constantly increasing. Ordinary asphalt materials generally have the disadvantages of high penetration, low ductility, and low softening point within the engineering range. The specific performance of asphalt is poor compression and crack resistance, poor plasticity, high temperature sensitivity, and narrow operating temperature range. [0003] Because ordinary asphalt is difficult to meet the requirements of modern road traffic for road surface quality, modified asphalt with better performance than ordinary asphalt has appeared i...
