STATE-OF-THE ART STUDIES/PRELIMINARY WORK SCOPES. TASK B - PAVEMENT MAINTENANCE COSTS. FINAL REPORT

Pavement maintenance cost is one of the three major components of the total life cycle cost for a specific highway segment. The capability of accurately estimating pavement maintenance cost depends directly on the quality of the available maintenance data. Two previous studies on life cycle cost of flexible and rigid pavements, conducted by the Department of Civil Engineering of the University of Maryland, for the Maryland State Highway Administration, encountered difficulties in estimating maintenance cost due to the lack of a complete maintenance data base. This study was undertaken to review and compile existing pavement maintenance data from other sources. The report consists of three parts. The first part presents the framework developed for compiling the data. This framework presents the organization of the compiled data and illustrates the content of a complete data set. The second part presents the compiled data, which includes data from 32 different States. Finally, the third part of the report summarizes the compiled data, according to the framework presented in Part I.
