摘要
为评估再生剂对老化沥青性能恢复程度的影响,文中选取老化沥青添加不同类型、掺量的再生剂,通过试验,分析再生剂对老化沥青性能的影响.试验结果显示,不同类型、掺量的再生剂对老化沥青性能有着显著影响,其中部分再生剂可有效改善黏结性能、提高变形抗力,并延长混合料的使用寿命.选择合适的再生剂类型、掺量可实现最佳的老化沥青性能恢复效果,为路面维护和修复提供科学依据和技术支持.
Abstract
In order to evaluate the effect of regenerant on the performance recovery degree of aged asphalt,different types and dosage of regener-ant were added to aged asphalt,and the effect of regenerant on the performance of aged asphalt was analyzed through experiments.The test re-sults show that different types and dosage of regenerants have significant effects on the properties of aging asphalt,and some of them can effec-tively improve the bonding properties,increase the deformation resistance,and extend the service life of the mixture.The results show that se-lecting the appropriate type and dosage of regenerating agent can achieve the best performance recovery effect of aging asphalt,and provide sci-entific basis and technical support for pavement maintenance and repair.
