While most published work from Europe has been concerned with evaluating binders’ resistance to rutting based on their stiffness (deformation resistance), work originating in the US has mainly been concerned with ranking binders based on their recoverability in a multiple stress form. This paper details the design of a new modified multiple stress–strain creep recovery (MS-SCR) test. The test is designed to evaluate binders’ rutting resistance based on two rutting resistance mechanisms: stiffness and recoverability. A preliminary investigation is presented in this paper followed by details of the design of the new modified test. A 40/60 penetration grade bitumen and bitumen-filler mastics prepared with three filler concentrations (35%, 50%, and 65% filler content by mass of mastic) were tested. In addition, two polymer modified bitumens (PMBs) using the same base bitumen type were examined for validation. Two parameters are introduced to characterise the short and long recovery in the new test. In terms of stiffness, the test allows the behaviour of binders at different stress levels and loading cycles to be studied and produces a new parameter that can quantify the degree of modification. Finally, a relationship between nonlinearity and normal force in the test was investigated.

尽管欧洲大多数已发表的论文都关注基于粘合剂的刚度（抗变形性）来评估粘合剂的抗车辙性，但源自美国的论文主要涉及基于粘合剂在多种应力形式下的可回收性对粘合剂进行排名。本文详细介绍了一种新的修改后的多重应力应变蠕变恢复（MS-SCR）测试的设计。该测试旨在基于两种抗车辙机理来评估粘合剂的耐车辙性：刚度和可恢复性。本文介绍了初步调查，然后详细介绍了新的改进测试的设计。测试了以三种填料浓度（按胶泥质量计分别为35％，50％和65％的填料含量）制备的40/60渗透等级的沥青和沥青填料胶泥。此外，检查了两种使用相同基本沥青类型的聚合物改性沥青（PMB）的有效性。引入了两个参数来表征新测试中的短期和长期恢复。在刚度方面，该测试可以研究粘合剂在不同应力水平和加载周期下的行为，并产生可以量化改性程度的新参数。最后，研究了非线性与法向力之间的关系。
