摘要
Abstract
Dry direct injection modification is an efficient and effective modification method to enhance the performance of asphalt mixtures.In this paper,ZM modifier was used as a research object to study the effect of direct injection modifier on the performance of asphalt and its mixtures.The rheological properties of ZM-modified asphalt were evaluated using dynamic shear rheology(DSR)and bending beam rheology(BBR)tests.The effects of ZM modifier on the road performance of asphalt mixtures were evaluated by rutting tests,freeze-thaw splitting,and other experiments.The test results show that ZM modifier can significantly improve the high-temperature rheological properties,elastic recovery ability,and reduce the temperature sensitivity of asphalt.ZM modifier asphalt mixtures have good road performance under the dry direct injection mixing process,with a 133％increase in dynamic stability and a 39.1％reduction in rutting depth.关键词
