晶须-生物油复合改性沥青的制备及其性能研究
Preparation and Properties of Whisker&Bio-oil Compound-Modified Asphalt
摘要
Abstract
In order to address the poor performance of base asphalt and the difficulty of the single modification to take into account its high-temperature and low-temperature performance,this study uses anhydrous calcium sulfate whiskers(ACSW)and bio-oil(BO)for compound modification of base asphalt.The basic physical properties,high-temperature stability,and low-temperature crack resistance of the compound-modified asphalt were systematically analyzed through three major index tests,storage stability test,and rheological properties test.The results show that the introduction of two modifiers,ACSW and BO,has a significant effect on asphalt performance and exhibits certain complementary effects.In particular,the mixing ratios of 6%ACSW with 2%BO and 8%ACSW with 3%BO can significantly improve the high-temperature stability and low-temperature crack resistance of the base asphalt,which provides a new research direction for the compound modification of asphalt.关键词
