The Analytical Research Of Asphalt Pavement Performance Evaluation Method

Since the reform and opening in China,the road construtions advance rapidly, the traffic in use increase largely,and the industrial grade enhance ceaselessly,too.With the development of highway project,the extension of time,the maintenance and administration look respecially important.But the costs in maintenance to input are limit annual.When it is less relatively,it's a requirement to consider how to allocate the finite fund to the most section of a highway which needs to be maintained mostly,then the road service performance can hold a appropriate service level.Thus a rational,effectional and correct pavement evaluation for road surface ,the maintenance is most important.The content of the paper include:first,it introduce the kinds of assessment method in China.Second,on the base of the data which is collected by HuLudao City.We find a method according with the actual condition and point out their merits and defects.Third,the paper adopt scientific evaluation method-AHP,because the weight coefficient of the foregoing evaluation method is selected according to experience.Fourth,we modify the parameter in response to the fact of the city HuLudao for tailing with it after we choose element model method as the only evaluation method.At last,after the assessment is over,we put forward relevant maintenance measure.
