Study On Performance Evaluation And Prediction Decision For Highway Asphalt Pavement

As a result of progress in the economic and technological advances, as well as the rapid development of science and technology, construction of expressways and the rapid development and, at the same time, the conservation and management of the problem. In order to extend highway asphalt road of life, and enhance road use performance, there is an urgent need to establish a rational Highway Road Management System, and the highway asphalt performance for effective management, and predictive, and according to road use performance in an accurate decision-making, through the adoption of preventive conservation of decision-making and to increase highway level of service to meet highway asphalt reasonable conservation purposes.In view of the above background, this article on highway asphalt using the performance evaluation and forecasting decision-making for the study. First of all,papers on the research background and significance, and summarizes the highway asphalt roads and a study on the current status; and, secondly, the comprehensive analysis of the highway asphalt using the performance of the factors and road from early disease of the reasons and the type, while at the same time establish the asphalt using the performance of the integrated evaluation methods; again, this analysis of the highway road use the performance of the forecast model with the advantages and disadvantages, and on the basis of the gray forecast the forecast road surface using the performance, and the Chengdu City highway of examples on a gray Prediction Method of road traffic forecast the effectiveness; and, finally,to the highway asphalt performance indicators to evaluate and forecast on the basis of a new highway road use Performance conservation decision-making methods, namely, a gray, won the conservation decision-making, and ChengYu Expressway instance the gray, won the effectiveness. This article to a certain extent, a highway asphalt use performance information for decision-making, as well as road management departments provide a reference value.
