High-skid-resistance wear-resistant composite modified asphalt mixture and preparation method thereof
The invention discloses a high-skid-resistance wear-resistant composite modified asphalt mixture and a preparation method thereof. The high-skid-resistance wear-resistant composite modified asphalt mixture comprises the following components in parts by weight: 100 parts of matrix asphalt, 25-30 parts of multi-source waste tire rubber powder, 2-3 parts of an SBS modifier, 5-8 parts of a stabilizer, 0.4-0.5 part of an anti-stripping agent, 1-1.5 parts of a surfactant, 4-5 parts of a coupling agent, 600-700 parts of limestone machine-made sand, 600-700 parts of bauxite aggregate, 700-800 parts of steel slag aggregate and 40-60 parts of mineral powder. According to the high-skid-resistant and wear-resistant composite modified asphalt mixture and the preparation method thereof, the obtained asphalt mixture has excellent mechanical properties, high skid resistance and wear resistance and better temperature stability and fatigue resistance, not only can improve the service performance of an asphalt pavement and prolong the service life of the asphalt pavement, but also is energy-saving, environment-friendly, green and low-carbon; the method has remarkable economic and social benefits.
本发明公开了一种高抗滑耐磨复合改性沥青混合料及其制备方法，按重量包括以下组成成分：基质沥青100份、多源废旧轮胎胶粉25～30份、SBS改性剂2～3份、稳定剂5～8份、抗剥落剂0.4～0.5份、表面活性剂1～1.5份、连接剂4～5份、石灰岩机制砂600～700份、铝矾土集料600～700份、钢渣集料700～800份、矿粉40～60份。本发明采用上述一种高抗滑耐磨复合改性沥青混合料及其制备方法，所得的沥青混合料具有优异的力学性能、高抗滑耐磨、较好的温度稳定性以及抗疲劳性能，不仅能改善沥青路面服役性能，延长沥青路面使用寿命，而且节能环保、绿色低碳，具有显著的经济社会双重效益。
