Use of Condition Surveys,Profile Studies,and Maintenance Studies in Relating Pavement Distress to Pavement Performance.

摘要

The report presents initial research directed toward the goal of relating pavement distress to pavement performance. To explore the use of condition surveys in solving the problem, 26condition surveys were conducted on two-tenths-mile-long pavement sections. Distress manifestations were recorded on data sheets and photographs were taken. To explore the use of pavement profile studies in solving the problem,the Surface Dynamics Profilometer was used to collect data on four of the pavement sections on which condition surveys had been conducted. The profilometer was also used to collect data for determining the serviceability index of the sections on which the condition surveys had been conducted. To explore the use of maintenance studies in helping to solve the problem of relating stress to performance,information about the Texas Highway Department maintenance procedures was obtained from a Texas Highway Department Maintenance Engineer.
