摘要
通过室内试验开展研究,结果表明:在机械力作用下的工艺,会使复合改性沥青的针入度减小,软化点提高;在高温作用下能使复合改性沥青的软化点和针入度同时增大,能使材料具有较好的高温稳定性,延度和低温抗裂性能,同时还具有较高的弹性恢复性能和较好的施工性能.
Abstract
Research was conducted by laboratory experiment,the results show that the penetration of the composite modified asphalt will be reduced and the softening point will be increased under the action of mechanical force.Under high temperature,the softening point and penetration degree of the composite modified asphalt can be increased at the same time,which can make the material have better high temperature stability,ductility and low temperature crack resistance,at the same time,it also has higher elastic recovery perform-ance and better construction performance.
