含有粒状橡胶改性粘合剂的再生沥青路面 (RAP) 的回收利用是一个重要问题，因为在美国的某些地区，某些此类路面的使用年限已超过 10 至 15 年。在本研究中，根据正常的回收实践，对实验室制备的橡胶粉改性 RAP 在 Superpave® 混合物中回收的可能性进行了实验室调查。设计并测试了六种混合物（三种含有实验室制备的粒状橡胶改性 RAP 的回收混合物和三种对照原始混合物）。混合物中使用了三种骨料和两种橡胶粉改性粘合剂。研究中使用的粒状橡胶改性RAP在实验室中进行了人工老化，并加速了老化过程。回收混合物中 RAP 的百分比为 15%。所有混合物的评估包括以下测试程序：间接拉伸强度、沥青路面分析仪和弹性...
The recycling of reclaimed asphalt pavements (RAP) containing crumb rubber—modified binder is an important issue because some of these types of pavements are more than 10 to 15 years old in some areas in the United States. In this study, a laboratory investigation was conducted on the possibility of laboratory-prepared crumb rubber—modified RAP being recycled in Superpave® mixtures according to a normal recycling practice. Six mixtures (three recycled mixtures containing laboratory-prepared crumb rubber—modified RAP and three control virgin mixtures) were designed and tested. Three types of aggregates and two types of crumb rubber—modified binders were used for the mixtures. The crumb rubber-modified RAP used in the study was artificially aged in the laboratory with an accelerated aging process. The percentage of the RAP incorporated into the recycled mixtures was 15%. Evaluation of all mixtures included the following testing procedures: indirect tensile strength, asphalt pavement analyzer, and resilient ...
