2013年在新疆克白线铺筑了 1km胶粉改性沥青SMA试验段,2023年对试验段进行了调查,就当年的实验数据以及本次调查数据,与常规SBS改性沥青SMA路段进行了对比分析,肯定了胶粉改性沥青的价值,也肯定了依据当地气候环境特征对路面材料和结构方案的选择.同时也发现了胶粉改性沥青存在的问题,并从橡胶沥青的技术发展趋势提出了解决办法.
In 2013,1km crumb rubber modified asphalt SMA test section was paved on the Ke-Bai highway.In 2023,an investigation was conducted on the same site,and the experimental data and follow-up survey data were compared and analyzed with general road sections of SBS modified asphalt SMA.The value of crumb rubber modified asphalt was affirmed,and the selection of materials and structure based on local climate and environmental characteristics was also affirmed.At the same time,the problems with crumb rubber modi-fied asphalt were also exposed,and solutions were provided based on the technological development of rubber asphalt.
