【摘要】 在区分沥青混合料水敏感性和水稳定性的基础上提出采用冲刷冻融试验环境模拟实际沥青路面水损害过程,并提出新的指标:剩余劈裂强度,结合劈裂强度建立起双指标的沥青混合料抗水损害性能评价方法,通过试验确定了水损害试验的冲刷时间及冲刷循环和冻融循环的先后次序。更多还原

【Abstract】 In the basement of differentiate water sensitivity and water stability,this paper advanced use eroding and freezing and thawing test to simulate water damage in bituminous surface and put forward a new indexes: residual tensile strength(RTS).The new evaluation method using two indexes tensile strength ratio and residual tensile strength for evaluating water damage resistibility of asphalt mixtures is developed,and determines the key techniques including how long fu eroding process and order of eroding cycle and freezing and thawing cycle ect.更多还原
