Abstract
This research is performed to analyze effect of using crumb rubber (CR) on the overlay design of Palembang City – Betung roads. Analysis of existing road conditions using the AASHTO 1993. This analysis based on deflection data using the Falling Weight Deflectometer (FWD). While, the overlay design analysis using CIRCLY 7.0 software to determine horizontal tensile strain (ɛh) for fatigue live and vertical compressive strain (ɛv) for rutting live parameters. The result showed that using CR can increase fatigue live into 66 % and rutting lives into 22 % for contribute pavement performance. To ensure the effect of CR in pavement-s performance, further research must be taken to find out if there are other effects that support.
