橡胶改性沥青储存稳定性试验研究
Experimental study on storage stability of crumb rubber modified asphalt
摘要
Abstract
Asphalt rubber (AR) and desulfurized rubber asphalt (DRA) were prepared, and their storage stability tests under different temperature or different storage time were conducted. Research shows that DRA is more segregated than AR after static storage at high temperature. After high speed shearing process, the large desulfurized crumb rubber particles are dispersed as minimal ones in the asphalt , its original particle size will not affect the performance of crumb rubber modified asphalt; but the ordinary crumb rubber mainly keep their particle cores after shearing. After high temperature storage and mechanical blending, the performance stability of DRA is obviously better than that of AR.关键词
