【摘要】 为探究表面活性剂类温拌剂对高黏沥青胶浆流变性能的影响，选用表面活性剂类温拌剂LKW,制备温拌高黏沥青胶浆，采用温度扫描试验、频率扫描试验、多重应力蠕变恢复试验(MSCR)以及低温剪切松弛试验评价其流变性能。结果表明，随着LKW掺量增加，温拌高黏沥青胶浆车辙因子先增后降，0.3%掺量时已低于原样水平，表明过量LKW会对其高温性能产生不利影响。MSCR试验进一步表明，导致高黏沥青胶浆高温性能下降主要原因是LKW降低了胶浆高温环境下抗变形及变形恢复能力。LKW使高黏沥青胶浆残余应力百分比下降，改善高黏沥青胶浆低温松弛性能，从而提高其低温抗裂性。更多还原

【Abstract】 To investigate the effect of surfactant based warm mix agents on the rheological properties of high viscosity asphalt mastic, a surfactant based warm mix agent LKW was selected to prepare warm mixed high viscosity asphalt mastic. The rheological properties were evaluated using temperature scanning tests, frequency scanning tests, multiple stress creep recovery(MSCR) tests, and low temperature shear relaxation tests. The test results show that as the LKW content increases, the rutting factor of the warm mixed high viscosity asphalt mastic first increases and then decreases. At the 0.3% content, it is already lower than the original sample level, indicating that excessive LKW has an adverse effect on its high temperature performance. The MSCR test further indicates that the main reason for the decrease in high temperature performance of the high viscosity asphalt mastic is that LKW reduces the mastic’s ability to resist deformation and recover deformation under high temperature conditions. LKW reduces the residual stress percentage of the high viscosity asphalt mastic, improving its low temperature relaxation performance, thereby enhancing its low temperature crack resistance.更多还原
