AASHTO T 350-19包括通过多重应力蠕变恢复（MSCR）试验测定沥青粘合剂的恢复率和不可恢复蠕变顺应性。使用动态剪切流变仪（DSR）在规定温度下进行MSCR试验。用于处理T 240（滚压）中的残留物 薄膜烘箱试验（RTFOT）。回收率百分比值旨在为确定聚合物改性和未改性沥青粘合剂的弹性响应和应力依赖性提供一种方法。

AASHTO T 350-19 covers the determination of percent recovery and nonrecoverable creep compliance of asphalt binders by means of the Multiple Stress Creep Recovery (MSCR) test. The MSCR test is conducted using the Dynamic Shear Rheometer (DSR) at a specified temperature. It is intended for use with residue from T 240 (Rolling Thin-Film Oven Test (RTFOT)).The percent recovery value is intended to provide a means for determining the elastic response and stress dependence of polymer modifed and unmodified asphalt binders.
