Numerous attempts to study adhesion properties between the coarse aggregate and asphalt and then study effect of additives materials and filler aggregate (fine) by using three types of pure asphalts (according to penetration grade 40/50, 60/70 and 85/100), which obtained from Durah refinery. Low density Polyethylene as additive material in three percent (0%, 2% and 4%) is used too, and limestone filler in two percent (0 % and 4%) are made. The surface tension stress theory between asphalt, aggregate and water is applied at assuming the aggregate which used are hydrophilic type (explain this type as glass plane plate).
From the results are obtained, the asphalt viscosity improved by using additives materials (increasing surface tension force between asphalt and aggregate (adhesion forces) greater than using mineral filler materials, then increase ability of mixture asphalt to resist stripping.
