SBS改性沥青二次老化性能分析
Performance of Second Aging of SBS Modified Asphalt
摘要
Abstract
Asphalt recycling is an important part of the pavement recycling. For studying the variation of aging properties of SBS modified asphalt and asphalt mixture after two times of aging, lots of experiments have been done about the original sample, the first aging, the regeneration, second aging of SBS modified asphalt and their mixture. The results show that the aging properties of SBS modified asphalt and asphalt mixture of secondary aging decline faster than the first time, the pavement performance of asphalt mixture may not meet the regulatory requirements after two times of aging. It is suggested that a right amount of SBS should be added in the SBS modified asphalt during the recycling process of SBS modified asphalt to improve the pavement performance of asphalt mixture.关键词
