地下道路低能耗降解尾气型罩面沥青混合料的路用性能研究

Research on Road Performance of Low-Energy Consumption and Degradation Tail Gas Pavement Paving for Underground Roads

基于环保与绿色道路建设要求,提出将二氧化钛水性环氧乳化沥青混合料用于地下道路低能耗降解尾气型罩面施工。为分析地下道路低能耗降解尾气型罩面混合料的综合路用性能,通过试验对比研究了基质沥青AC-5、SBS改性沥青SMA-10、环氧沥青AC-13及地下道路低能耗降解尾气型罩面混合料DE-10四种混合料的静态模量、高温性能、水稳定性能和抗疲劳性能。研究结果表明,地下道路低能耗降解尾气型罩面混合料具有优异的综合路用性能。

Based on the requirements of environmental protection and green road construction,it was proposed to use titanium dioxide waterborne epoxy emulsified asphalt mixture for the construction of low-energy degradation and degradation tail gas pavement paving for underground roads.In order to understand the comprehensive road performance of low-energy consumption and degradation tail gas pavement paving for underground roads,the base asphalt AC-5,SBS modified asphalt SMA-10,epoxy asphalt AC-13,and underground road low-energy degradation were compared through static modulus tests,high temperature performance tests,water stability tests and fatigue resistance tests.The results showed that the low-energy consumption and degradation tail gas pavement mixture for underground roads exhibited excellent comprehensive road performance.
