• Abstract:
  Automated distress collection systems have been developed over the years to evaluate the condition of pavements. The simplest method is to have a person ride or walk along the road and visually evaluate it. However, there are a number of problems with this approach, including the boredom attendant on such a mundane task and the subjective and arbitrary nature of the evaluations due to human nature. Because visual evaluations of pavements are by nature subjective and arbitrary, automated systems have been developed in an attempt to make the evaluation procedure more objective and consistent. In 1993, a study by Cable recommended that automated equipment be used to improve the quality of pavement condition data. Recently, another study was completed looking into the feasibility of using automated distress data in Iowa’s county need study. The study concluded that use of the automated distress data collected for the Iowa Pavement Management Program
