【摘要】 采用三种应力下的重复蠕变恢复试验得到的恢复柔量,确定了零剪切黏度,并对结果进行了分析,指出对高粘橡胶改性沥青来说,当应力较大时,7.5 s~8 s的恢复时间不够达到恢复柔量的恒定值,且零剪切黏度在60℃温度下测量数据与车辙的测量数据是相关的。更多还原

【Abstract】 In this paper,the zero shear viscosity values are determined by the recovery compliance of repeated creep recovery tests at 3 kinds of stresses and the results are analyzed. For high viscosity rubber modified asphalt,when the stress is larger,the recovery time of 7. 5 ~ 8 seconds is not enough to keep the constant value of compliance. And ZSV measurements at 60 ℃ would facilitate correlation with rutting measurements which are commonly performed at this temperature.更多还原
