复合温拌沥青及其混合料性能研究
Study on the Performances of Composite Warm Mix Asphalt and Asphalt Mixture
摘要
Abstract
To reduce the mixing temperature of asphalt mixtures and achieve energy conservation and emission reduc-tion,the effects of the surfactant-based warm-mix additive Evotherm and the organic viscosity-reducing addi-tive WSG-HO2 on asphalt performance,as well as their respective optimal dosages,were investigated using the control variable method.Subsequently,the two additives were compounded with base asphalt to prepare a composite warm-mix asphalt.The viscosity,penetration,softening point,ductility,and other properties of the composite warm-mix asphalt were systematically evaluated.Taking AC-13 as the target gradation,the mix proportion of the asphalt mixture was determined,and the comprehensive road performance of the compos-ite warm-mix asphalt mixture was experimentally studied.The results indicate that the composite warm-mix asphalt can lower the mixing temperature of the asphalt mixture by 32 ℃ while maintaining satisfactory road performance.关键词
