Applying new techniques such as numerical method would prepare more facilities to estimate the result of experimental studies.In this research, performance of asphalt mixtures prepared with recycled aggregates was measured by using response surface analysis method. For this aim, recycled aggregates obtained from chip seal roads were used as fine aggregates with new aggregates in asphalt mixtures. Recycled aggregates were added into the mixture with 25, 50, 75, 100% ratios. 50/70 and 70/100 penetration bitumens were used as binder in the prepared mixtures. In order to measure the perfromance of mixtures, Marshall stability, flow, cantabro were performed. The results obtained from response surface analysis showed that, the estimation models have R2 values higher than 80. This means that, response surface analysis can be used as a numerical method for the prediction of asphalt mixture perfomance.
