HMA made from a specific materials may be need to strength when is subject to water in the pavement layers because of the ability of water to prevent the binder to not adhere to the aggregate and it will not to hold the pavement together which leads to rapid failure of the pavement .This is often referred to as stripping that it makes treatments such as enhance the pavement layers with certain materials from presence of water . Test methods are study to measure the resistance of different mixturesutilizing recycled aggregate to saturation periods and also to measure the significance of using theanti-stripping as additives. This research was in exposing the three types of asphalt, one 60% of recycled aggregate from asphalt mixture and the other 60% recycled aggregate from the concrete mix and third mix using 10% from wax as additive by weight of asphalt, to merging in water with different durations represented as (3, 7, 15, 28) days . Different experimental tests were also conducted and compared the results with virgin asphalt mixture for the same conditions. The tests used was (Marshall stability and flow), bulk density, indirect tensile strength, compressive strength, sensitivity to temperature, resilient modulus. The investigation was successful so it gave valuable results showing improved asphalt resistance to moisture damage when using recycled aggregate from previous mixes and provingthe wax effectiveness in increasing these resistance and improve HMA properties
