随着国民经济的发展,交通量日益增大,大型化车辆、重载、超载车辆比例逐步增加,因此,对路面的要求越来越高。改性沥青可以提高路面的高温抗车辙性能、低温抗开裂性能、抗水稳定性能、抗老化性能和行车舒适性能,为此改性沥青用量增长迅速。目前,中国国内改性沥青的研究和应用主要集中在PE、SBR和SBS等类型,为满足日益增长的改性沥青需求,中国石油辽河石化分公司针对改性沥青的市场情况和不同地域的改性
With the development of the national economy, traffic volume is increasing day by day, and the proportion of large vehicles, heavy vehicles and overloaded vehicles is gradually increasing. Therefore, the requirements for pavement are getting higher and higher. Modified asphalt can improve the high temperature rutting resistance of the road surface, low temperature anti-cracking performance, water stability, anti-aging properties and driving comfort, for which the amount of modified asphalt increased rapidly. At present, the research and application of domestic modified bitumen are mainly in the categories of PE, SBR and SBS. In order to meet the increasing demand for modified bitumen, PetroChina Liaohe Petrochemical Branch Co., Ltd., in view of the market conditions of modified bitumen and the changes in different regions Sex
