Abstract

The invention discloses an activated waste rubber powder noise-reducing micro-surfacing mixture. Said composite additive is the mixture of polyphenylsiloxane, N,N-dicyclohexyl-2-benzothiazyl sulfenamide, chloroprene rubber, polypropylene glycol diacrylate, polytetrahydrofuran ether and cross-linking agent; Improve the compatibility and bonding performance of rubber powder and mineral aggregates with asphalt, improve the noise reduction effect, and improve the viscosity, toughness and toughness of asphalt through asphalt modifiers, thereby improving the weather resistance and water resistance of the noise reduction micro-surface and fluidity resistance, enhance the noise reduction effect, increase the speed of micro-surface strength formation through octadecyltrimethylammonium chloride, and achieve the purpose of rapid opening of traffic; enhance the compatibility of each component through compound additives, and The mechanical energy is converted into the kinetic energy of the micromolecular chain or segment, and the mechanical energy is converted into thermal energy to dissipate, improving the noise reduction effect.

Description

technical field

[0001] The invention relates to the technical field of asphalt pavement preventive maintenance, in particular to an activated waste rubber powder noise-reducing micro-surfacing mixture. Background technique

[0002] Micro-surfacing technology is an economical, fast, effective, environmentally friendly, open traffic, fast, and long-life pavement preventive maintenance technology. With its outstanding advantages in improving road surface skid resistance, sealing water, improving road appearance and smoothness, etc., It has become the mainstream technology for preventive maintenance of high-grade highways and urban roads in my country. However, when micro-surfacing is used, the noise inside and outside the vehicle during driving, that is, tire-road noise, is significantly higher than that of hot-mixed and hot-paved asphalt pavement, which greatly affects the driving comfort of the road surface and restricts the promotion and application of micro-surfacing technol...
