Abstract
The use of automated pavement condition survey systems has been a goal of highway managers for many years. With the advent of the Strategic Highway Research Program's (SHRP's) Long-Term Pavement Performance study the need for permanent, high-resolution pavement distress records arose. To meet this need through the use of state-of-the-art technology, SHRP chose to use automated RoadRecon survey systems to obtain permanent high-resolution records of pavement surface distress and transverse profile. The survey system and procedures used in the field to record the transverse profiles on 35-mm film, the procedures used in the office to process the films, the methods used to analyze the transverse profiles to report the rut depth data, and the quality-control procedures employed are all discussed. The data for the first three rounds of measurement on many of the sites are available. The results of some preliminary analysis of these data are also described.
