耐久性高模量沥青混合料性能研究

Study on the Performance of High Modulus Asphalt Mixture

通过试验对溶剂脱30#、氧化30#耐久性高模量沥青混合料性能进行研究,试验 结果表明:氧化30#沥青耐久性高模量混合料在高温稳定性方面,性能较为优异,比溶剂脱 30#沥青耐久性高模量混合料的高温稳定性能要好,但是其抗疲劳性能则很差;相同温度条 件下溶剂脱30#耐久性高模量沥青混合料间接拉伸模量要高于氧化30#,表明前者的力学性 能更好。因此,氧化30#沥青耐久性高模量混合料有待于继续进行深入研究与改良,溶剂脱 30#沥青耐久性高模量混合料可以尝试在以后的试验路上进行应用研究。

By experiments,solvent stripping 30#,oxidation 30#durability high modulus asphalt mixture performance is studied.The results show that with poor at anti-fatigue performance,oxidation 30#durability high modulus asphalt mixture is outstanding at high temperature stability,better than solvent stripping 30#asphalt.Under the same temperature condition,the indirect tensile modulus of solvent stripping 30#durability high modulus asphalt mixture is higher than that of oxidation 30#,indicating that the mechanical properties of the former are better.Therefore,oxidized 30#durability high modulus asphalt mixture needs further study and improve.Solvent stripping 30#asphalt durability high modulus asphalt mixture can be tried to be applied in test road.
