ON APPLICABILITY OF PERFORMANCE ANALYSIS BASED ON THE RESULTS OF CIRCULAR ROAD TESTS TO ACTUAL ASPHALT PAVEMENTS

Abstract

This paper describes an application of performance analysis based on the results of circular road tests to actual asphalt pavements. The performance of the test pavements was investigated in the eight lines in Hyogo Prefecture; in all the test pavements, compound slag and HMS were used as the upper basecourse. The serviceability indices calculated from the performance analysis were compared with those derived from actual measurement. It is shown that the serviceability calculated from actual measurement is generally in good agreement with the analyzed performance curves for the sections designed for the traffic types A and B, although some scatter is recognized.
