摘要
摘要沥青的性能对沥青层的耐久性、抗疲劳性能和低温性能有很大的影响。因此，经常对沥青的成分进行改性，以改善沥青混合料的性能。丁烯苯乙烯(SBS)是近年来应用最广泛的添加剂。研究人员正试图通过这种聚合物基添加剂来改善粘合剂的内聚性和粘合性能。本研究采用160/220渗透级沥青和Kraton D 1101 SBS。本研究包含了一种新的评估，用于确定sbs改性粘合剂在-1°C， -3°C和-5°C下的内聚行为。该评价结果与常规和流变试验结果进行了比较。因此进行了渗透、软化点、粘度、动态剪切流变仪和弯曲梁流变仪试验。最后，发现低温拉伸试验的结果与其他试验的结果一致;因此，它们也证实了sbs改性粘合剂在低温下的内聚行为。
Evaluation of the Cohesive Properties of SBS-Modified Binders at Low Temperatures
Abstract The durability, fatigue resistance, and low-temperature behavior of asphalt layers are greatly affected by the properties of bitumen. Therefore, the composition of bitumen is frequently modified to improve the performance of asphalt mixtures. Sty-rene-butadiene-styrene (SBS) has been the most often used additive recently. Researchers are trying to improve the cohesive and adhesive properties of binders by such polymer-based additives. In this study, 160/220 penetration grade bitumen and Kraton D 1101 SBS were used. The present study contains a new evaluation for determining the cohesive behavior of SBS-modified binders at -1°C, -3°C, and -5°C. The results of this evaluation were compared to conventional and rheological test results. Penetration, softening point, viscosity, dynamic shear rheometer, and bending beam rheometer tests were therefore conducted. Finally, the results of a low-temperature tensile test were found to be consistent with the results of the other tests; hence, they also confirm the cohesive behavior of SBS-modified binders at low temperatures.
