This paper is studying the effect of two different heating temperature of RAP on performance of water sensitivity tests, the Indirect Tensile Strength Ratio (TSR). the best gradation and optimum asphalt content was Selected according to Superpave method. Superpave Gyratory Compactor (SGC) used to compact mixture with 100-mm diameter. Four different percentages (20,30,40 and 50) of RAP used for preparation mixes to compared with virgin mixture. The test results indicated that addition RAP to mixes shows significant increase on resistance of moisture damage (TSR) for 110 c ْ for all percent. For 140 c ْ showed (TSR) increase to threshold (20%) of RAP while (TSR) decline for another percent but still above the standard limit of 80%.
