AASHTO TP 123-16（2020）涵盖了使用动态剪切流变仪（DSR）评估沥青粘合剂在单调恒定剪切速率荷载下抗屈服型破坏的粘合剂屈服能试验（BYET）。本试验程序也可适用于使用DSR代替传统延展性试验（T 51）和弹性恢复试验（ASTM D6084）进行替代试验程序。该试验方法可用于未老化材料和使用T 240（RTFOT）和/或R 28（PAV）老化的材料，以模拟在役沥青路面的预计老化。

This test method covers the Binder Yield Energy Test (BYET) for evaluation of asphalt binders’ resistance to yield-type failure under monotonic constant shear-rate loading using the Dynamic Shear Rheometer (DSR). This test procedure can also be adapted for performing surrogate test procedure using the DSR in place of the conventional ductility test (AASHTO T 51), and the Elastic Recovery test (ASTM D6084/D6084M). The test method can be used with unaged material and material aged using AASHTO T 240 (RTFOT) and/or R 28 (PAV) to simulate the estimated aging for in-service asphalt pavements.
