DAMA is the Darin Asphalt Modified Additive as a polymer modified Asphalt which has been developed for use in a wide range of highway and airfield paving applications,especially OGFC Hot mix production, installation, and compaction are carried out using sandard mix specification this method of production reduce heating, transportation costs for the modified asphalt cement, because Dry type modification during Hot Mixing procedure at plant. avoid the need for tank storages as to other conventional Modification Method. eliminate possible degradation ; extended storage and large temperature fluctuations tend to reduce the quality and performance of pre-blended modified binders.(wet mix type)
