Description	Journal: Iop Conference Series: Materials Science and Engineering Warm mix asphalt (WMA) is a new sustainable technology that gives an economic and environmental beneficial value by means of production temperature decrease of the asphalt mixture by (10-40) °C. The difference between conventional Hot Mix Asphalt (HMA) and WMA mixes were analyzed, in this study, in term of marshall properties which conducted on specimens are produced of: Al-Nibaae source aggregate and Al-Dorah Refinery source asphalt binder (40/50 PEN) modified by two organic additives (Asphaltan A and Asphaltan B). The laboratory tests to determine the mechanical properties of asphalt binder and aggregates are conducted. Two types of aggregate gradation mixtures are designed to perform HMA and WMA preparations using Marshall design method. Doses of 1, 2, and 3% of the additives by total weight of asphalt binder were chosen. WMA mixtures are prepared at 40 °C less than HMA specimens and produced by the same procedure. Many changes on mechanical and physical properties are observed due to the existence of the additives and dosages. The results show that the resulted properties are enhanced by using Asphaltan A and Asphaltan B as WMA additives to the Iraqi asphalt binder.
