青海省化学抗剥落剂对改善酸性石料与沥青粘附性的研究

Improving Effect of Chemical Anti-stripping agent on Adhesiveness of Acid Stone with Asphalt in Qinghai Province

沥青与集料的粘附性直接影响到沥青路面的使用质量和耐久性,通过在酸性石料与沥青中掺入不同类型、不同剂量的抗剥落剂,进行粘附性和抗老化试验的对比分析,确定卡洛胺抗剥落剂为适用于青海地区改善酸性石料与沥青粘附性的抗剥落剂,并由此确定了抗剥落剂的合理掺量。

Adhesiveness of acid stone with asphalt directly impacts the service quality and durability of asphalt pavement. The contrast and analysis on adhesiveness tests and ageing resistance tests is carried on through mixing different types and dosages of anti-stripping agent into acid stone and asphalt. It is determined that Carlo Amine Anti-stripping agent adapts to improving the adhesiveness of acid stone with asphalt in Qinghai region. Thus the reasonable amount of anti-stripping is also identified.
