In this study, the performance of modified asphalt concrete mixes containing natural sand (desert sand and river sand ) and five replacement ratios for each one (0, 25, 50, 75 and 100% by weight of the sand passing sieve no. 8 and retained on sieve no 200) were evaluated. The performance of modified asphalt concrete mixes tensile strength, rutting is evaluated using indirect tensile test and wheel track test
