Through Infrared Adsorption Spectrum Analysis ( IR), Differential Scanning Calorimetry ( DSC), the influence of ultraviolet radiation ageing on the composition of bitumen is studied. In ultraviolet radiation ageing, the low temperature crack resistance, fatigue resistance of bituminous mixtures are studied.
并通过红外光谱（IR）和差示扫描热分析（DSC）研究了紫外线老化对沥青组成结构的影响，同时研究了紫外线老化对沥青混合料的低温和疲劳性能的影响。
The results have shown that tensile straightening between quenching and ageing has no effect on the crack propagation rate and fracture toughness, but has some effect on tensile properties of the sheet.
结果表明，淬火与时效间的板材拉伸矫直对裂纹扩展速率及断裂韧性无影响，而对力学性能有影响。
