摘　　要：基于哈萨克斯坦高等级公路路面病害频发及改性沥青技术薄弱的现状,为研究我国聚合物改性沥青技术在哈萨克斯坦的适用性,依托哈萨克斯坦国家级公路建设项目(TKU项目)开展了SBS改性沥青配合比设计、性能研究及适用性分析,结果表明,BH开100/130添加2.5%橡胶油+3.0%SBS或3.0%橡胶油+3.5%SBS进行改性所制备的改性沥青可满足PG58-34与PG58-40两个气候区使用要求,而添加3.5%橡胶油+3.5%SBS的改性沥青可满足TKU项目所经过的三个气候区使用要求。结合TKU项目气候分区对沥青胶结料的性能要求,建议采用由巴甫洛达尔石油化工厂生产的BH开100/130道路石油沥青与3.5%橡胶油及3.5%SBS所制备的改性沥青。本研究成果可为TKU项目的实施及我国改性沥青技术在海外的推广应用提供有益的参考。Based on the current situation of frequent pavement diseases and weak modified asphalt tech-nology in Commonwealth of Independent States,in order to study the applicability of polymer modified asphalt in Kazakhstan,the mix proportion design and performance research of SBS modified asphalt are carried out based on the national highway construction project of Kazakhstan(TKU project).The results show that,the modified asphalt prepared by BHI100/130 with 2.5%rubber oil&3.0%SBS L30-01 or with 3.0%rubber oil&3.5%SBS L30-01 can meet the use requirements of two climatic regions,pg58-34 and pg58-40.And the modified asphalt with3.5%rubber oil &3.5%SBS L30-01 can meet the requirements of three climatic regions of TKU project.According to the performance requirements of asphalt bonder by TKU project climatic regions,it is recommended to use the modified asphalt BH100/130,which is prepared by Pavlodar petrochemical plant,adding3.5% Uniplast&3.5%SBS L30-01.The research results can pro-vide useful reference for the successful implementation of TKU project and the application of modified asphalt technology abroad.
