【摘要】 随着新疆公路建设里程增加,交通量逐渐增大,沥青路面已出现了不同程度早期损坏现象,深入揭示新疆地区沥青路面使用性能衰变规律,对于延长沥青路面使用寿命具有重要工程价值。论文重点研究了新疆地区沥青路面病害种类及成因、衰变方程和衰变规律等内容。论文通过实地调查总结了新疆地区沥青路面病害种类,并结合路面使用性能检测及室内实验结果,分析了新疆地区沥青路面病害成因。论文在大量数据回归分析基础上提出了新疆地区沥青路面使用性能指标“PCI”、“RQI”和“弯沉”衰变模型参数,得出了新疆地区沥青路面使用性能衰变模型,并通过对实体工程的计算分析,揭示了新疆地区沥青路面使用性能衰变规律。更多还原

【Abstract】 With the increase of the highway construction and the traffic volume in Xinjiang, early damage with different characteristics has occurred in asphalt pavement. It is very meaningful to analyze the decay law of asphalt pavement performance in Xinjiang for prolonging the service life of asphalt pavement.This paper mainly studies on the asphalt pavement diseases and the performance decay equation and decay law in Xinjiang region.This paper sums up the asphalt pavement diseases types in Xinjiang by site investigation, analyzes the disease causes by the performance measurement and laboratory experiments.On the basis of data regression analysis, this paper suggests decay model parameters of asphalt performance indicators, including PCI, RQI and deflection, attains an asphalt pavement performance decay model in Xinjiang region, and then gets the asphalt pavement performance decay law in Xinjiang by the calculation analysis on practical project cases.更多还原
