Abstract

本发明涉及道路工程技术领域,尤其涉及一种温拌同步再生SBS改性沥青的多目标性能耦合设计方法,通过测试确定老化SBS改性沥青的老化程度,据此确定双组分同步再生剂与温拌剂的最佳掺量。随后建立新-旧SBS改性沥青扩散模型与融合度计算模型,定量分析不同温度及老化沥青掺量下的新-旧沥青融合度。在此基础上构建融合度图谱,通过划定各性能指标的阈值得到各项性能均衡的可行性设计方案区间,从而确定最佳拌和温度与老化SBS改性沥青的最大掺量。本发明能在兼顾多目标性能的前提下快速确定老化SBS改性沥青的最大允许掺量及其对应的最佳拌和温度,为高性能再生SBS改性沥青路面的耐久性设计提供可靠的理论依据。
