EVALUATION OF EFFECTIVENESS OF PAVEMENT PREVENTIVE MAINTENANCE. PROCEEDINGS OF STRATEGIC HIGHWAY RESEARCH PROGRAM AND TRAFFIC SAFETY ON TWO CONTINENTS , GOTHENBURG, SWEDEN, 27-29 SEPTEMBER, 1989. HIGHWAY OPERATIONS. CONCRETE AND STRUCTURES

There is little information available concerning the cost-effctiveness of preventive maintenance treatments applied to pavements. This inhibits justifying funds to those who must allocate limited funds, and it hinders fund allocation analysis through pavement management systems. In addition, there is little information identifying the best time in the service life of pavements to apply to treatments. Nor is there information concerning the influence of environment, different traffic loads, support conditions, and other factors on the effectiveness of preventive maintenance treatments. Strategic Highway Research Program (SHRP) Project H-101, Pavement Maintenance Effectiveness, was developed to address those problems. The goals of SHRP Project H-101 include: (1) to establish the effectiveness of typical maintenance treatments in prolonging the life of asphalt and concrete pavements; (2) to develop methods of evaluating the cost-effectiveness of maintenance treatments; and (3) to develop information on the effective timing of the application of maintenance treatments. The basic approach of the study is to evaluate the field performance of pavements with and without the preventive maintenance treatments and record the data. The base of data will allow researchers, maintenance engineers, and pavement managers to develop a bench-mark analysis of the effectiveness of preventive maintenance treatments in extending the service life of pavements. This information will then be used to determine the cost-effectiveness of the preventive maintenance treatments.
