Research On The Decay Law Of Asphalt Pavement Performance In Xinjiang

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.
