沥青混凝土路面车辙病害原因的调查分析与评价

Investigation and Analysis of Rutting Distress on Asphalt Pavements

对江苏省某段高速公路沥青混凝土路面车辙病害的原因进行分析调查 ,通过现场取芯试验 ,分析了路面各沥青层厚度、沥青混凝土路面现场空隙率以及沥青混合料级配油石比组成 ,结合路面结构的有限元分析 ,提出了沥青混凝土路面车辙防治的技术措施。

Through the investigation of rutting of a section of asphalt pavement in Jiangsu Province,the reasons of the rut formed on pavements are analyzed. On the basis of tests the thickness of each layer in asphalt pavements,the air void,the asphalt content and the gradation of mixture are analyzed. Some suggestions for asphalt pavements are given with the finite analysis of pavement structure.
