| 摘 要： | 温拌再生沥青混合料是基于沥青温拌技术和再生技术发展而来的新型环保型沥青混合料.研究了基于Sasobit添加剂的温拌再生沥青混合料压实特性随压实温度和旧沥青混合料(RAP)掺量的变化规律,定量评价了旧料(RAP)掺量分别为0%、15%、30%、45%及60%在压实温度分别为140℃、130℃、120℃、110℃和100℃时温拌再生沥青混合料的体积参数的变化,确定了适合温拌再生沥青混合料的压实温度.

| Abstract: | Warm-recycled asphalt mixture is a new type of pavement material that can not only reduce the mixing temperature and exhaust gas emissions,but also increase the proportion of RAP addition.The compaction characteristics of warm-recycled asphalt mixture is evaluated by changing the compaction temperatures and,that is,the compaction temperatures are 140℃,130℃,120℃,110℃and 100℃,and the RAP proportions are 0%,15%,30%,45% and 60% respectively.Finally,the compaction temperature for each mixture is recommended according to the test results. |
