摘要：	In 1992 the managing authority of the French National Roads Network decided to modernize the means of evaluating the condition of its roads. The tool set up to do this is based primarily on a systematic survey of pavement surface damage, completed by skidding resistance measurements. Sixteen Regional Public Works Laboratories were assigned to gather road information. For the evaluation tool to have the expected qualities, there has been a special effort to make the damage survey a means of investigation as reliable as a measurement. The laboratories use a highly formalized method that precisely fixes the conditions in which the survey must be performed, the type of information to be recorded, and its codification. Training incorporating an introduction to the method, practical work on sections of road, and days spent coordinating the terms complete the arrangements made to ensure the reliability of the survey. The information gathered on the road network is then realigned on the official distance markings of the road network and accepted in 200-m lengths before being transferred to a data base. There it is processed to provide a series of ratings qualifying the condition of the pavement structures and the safety that the pavement offers the user.
