改性沥青混合料路用性能的对比研究

摘要

High modulus asphalt mixture has a good anti-rutting performance as a new type of pavement material. In order to study the comprehensive properties of high modulus asphalt mixture with different modifiers, AC-25C high modulus asphalt mixture is used as the study object, and the pavement performance of high modulus asphalt mixture with different modifiers is analyzed through the test study of the high temperature performance, deformation performance, water stability and low temperature performance of three kind of asphalt mixtures of 70 # ordinary, SBS and RA, then the superior of high modulus asphalt mixture with modifiers is shown through comparison.%高模量沥青混合料作为一种新型路面材料,具有优良的抗车辙性能.为了研究掺加不同改性剂高模量沥青混合料综合性能,以AC-25C高模量沥青混合料为研究对象,通过对70#普通、SBS和RA三种沥青混合料的高温性能、变形性能、水稳定性和低温性能等试验研究,对比试验和分析了不同改性剂下高模量沥青混合料的路用性能,从而比较出掺加改性剂的高模量沥青混合料的优越性.
