BENDING FATIGUE STRENGTH OF PAVEMENT CONCRETES WITH NORMAL AND RECYCLED AGGREGATES

Abstract

This paper presented fatigue strength of plain pavement concrete and roller compacted concrete with recycled aggregate. Comparative studies on the bending fatigue strength conducted with other researchers are also included. Bending fatigue strength characteristics of recycled aggregate concrete are emphasized. In the study the modified Goodman diagram is fairly well applicable for the determination of fatigue strength of recycled aggregate concrete. Weibull and the normal probability distribution functions agree well with the experimental results.
