经过对4种常用抗剥落剂的比选,选择几种不同的改善酸性集料与沥青粘附性的方案,并进行路用性能试验评价,各种改善方案下的沥青混合料在水稳性、低温抗裂性能以及高温稳定性能等方面均有所提升,其中通过石灰岩石屑代替片麻岩石屑的措施改善效果最为明显。在内蒙古某一级公路对比只掺加消石灰与同时掺加消石灰和抗剥落剂的措施铺筑酸性集料沥青混合料下面层试验路段,通过室内试验及现场观测路用性能良好。 After comparing and selecting four kinds of common anti-stripping agents, several different schemes to improve the adhesion of the acid aggregate and asphalt were selected, and the road performance tests were conducted to evaluate the effectiveness of the asphalt mixture under water-stability , Low temperature crack resistance and high temperature stability and other aspects have been improved, among which the lime stone chips instead of gneiss stone chips to improve the effect of the most obvious. In a certain highway in Inner Mongolia, only the addition of hydrated lime with lime and anti-stripping agent at the same time measures the construction of acid aggregate asphalt mixture under the road test section, through the indoor test and observation of the road with good performance.
