路面强力剂
摘要：
一种沥青路面强力剂，属于一种筑路用沥青混合料的添加剂，目的是解决现有技术中用于筑路沥青的内掺添加剂存在的需要额外昂贵的专用设备、操作复杂的问题或外掺添加剂存在的低温性能、水稳定性及疲劳性能较弱、需改变沥青混合料的最佳油石比、应用成本大的问题，由下述重量百分比的组分构成：分子量为3万～6万的LLDPE 50～65％、分子量为2万～5万的LDPE 20～35％、针入度为6mm～8mm的道路沥青1～2％、针入度为0mm～0.5mm的湖沥青3～10％、纤维稳定剂5～15％、抗剥落剂1～4％、SASOBIT聚烯烃1～4％。本发明可作为沥青混合料的添加剂，作为沥青路面的强力剂。
摘要（英）：

A strengthening agent for asphalt pavement, which pertains to a additive to asphalt mixture for road building, and aims to solve the problem that application of internal mixing additives in asphalt for building a road needs very expensive special equipments which are hard to operate, or that weakness in low temperature performance, water stability and fatigue property of external mixing additivesleads to the need of changing optimum asphalt-aggregate ratio of asphalt mixture, and great cost in application. The strengthening agent comprises 50-65% by weight of LLDPE with molecular weight between 30000-60000, 20-35% by weight of LDPE with molecular weight between 2000-5000, 1-2% by weight of road asphalt with penetration between 6mm-8mm, 3-10% by weight of lake asphalt with penetration between 0mm-0.5mm, 5-15% by weight of fiber stabilizer, 1-4% by weight of anti-stripping agent, 1-4% by weight of SASOBIT polyolefin. The invention can be used as additive for asphalt mixture, and strengthening agent for road asphalt.
