摘要
抚顺地处东北地区,年最大温差达60℃左右,受温度影响路面极易出现车辙和开裂。沥青的单一改性已满足不了路面的需求,寻找高低温性能兼顾的改性沥青成为迫切的需要。该文介绍一种新的沥青混合料改性剂-PRCR。该改性剂能够在保证高温抗车辙的同时兼顾低温抗裂性,其性能优于SBS等改性沥青混合料。
Fushun is located in the northeast region.Its maximum annual temperature difference is about 600C.The pavement is easy rutted and cracked because of temperature influence.The single modification of asphalt has not satisfied the pavement demand.It is urgently required to find the modified asphalt taking account of the low and high temperature performances.The article introduces a new asphalt mixture modifier-PRCR.This modifier can guarantee the rutting resistance under the high temperature and also taking account of the cracking resistance under the low temperature.Its performance is more excellent than the modified asphalt mixtures of SBS and so on.
