PROCEEDINGS FOR THE AUTOMATED PAVEMENT DISTRESS DATA COLLECTION EQUIPMENT SEMINAR, AMES, IOWA, JUNE 12-15, 1990

Pavement rehabilitation decisions require reliable performance data that can be used to establish current and predicted conditions of a highway system. Collection of the data by manual methods is usually costly, requires large amounts of manpower, involves high personnel safety risks, and tends to be very subjective and not very repeatable. The development of automated procedures that use cameras and microcomputer technology is proving to be an aid in solving many of these problems. Several equipment manufacturers were present to demonstrate the use of their systems. They were observed by some 275 participants, representing State and local highway agencies and countries from around the world. Experts in the pavement distress identification and analysis area presented papers dealing with various aspects of the subject. The proceedings includes copies of all the presented papers, a list of seminar participants, summary information and sample output for several devices, and questions/answers concerning the topic.
