This research investigate the applicability of using the waste iron powder (WIP) as an aggregates in asphalt pavements and it provides a solution of an environmental problem in the world.In this research, a number of Asphalt tests are conducted which are: sieve analysis, specific gravity, absorption, adsorption, and scanning electron microscopic. Marshal samples are prepared using both conventional blending aggregates and (WIP) to investigate the properties of the asphalt mix: stability, flow, bulk density, air voids and comparing the results with the specifications. WIP was introduced in the asphalt mixture in grinded form 0–2.00 mm. Marshal mix design procedure was used, first to determine the Optimum Bitumen Content (OBC) and then further to test the modified mixture properties. In total, (58) samples were prepared, 30 samples were used to determine the (OBC) for two stages and the remaining were use to investigate the effects adding different (WIP) percentages to asphalt mix . At the first stage, the OBC was 5 % by weight of asphalt mix. The results showed that it is possible to use the WIP in preparing the asphalt binder course. WIP content of 5 % by weight of aggregate for asphalt mix is recommended as the optimum WIP content for the improvement of performance of asphalt mixMoreover, at the first stage, the ratio of sand was 5% from weight ofaggregate, Four proportionsof WIP by weight of aggregates were tested 1.25, 2.5, 3.75, and 5%.Besides, testing of ordinary asphalt mix. Asphalt mix modified with this percentage has approximately 23% higher stability valuecompared to the conventional asphalt mix. The second stage is done to ensure the results that appeared at first stage by increase the ratio of WIP 7.5 and 10%.Asphalt mix modified with higher percentages of WIP shows higher bulk density, higher flow and higher air voids.
