Investigating the Effect of Olive Husk Ash on the Properties of Asphalt Concrete Mixture

Technology in transportation used available resources to make it safe, fast, suitable, easy, economic, and environmental transport people goods. Olive Husk became an problem as waste materials especially the Middle East where huge quantities are found. The objective of this research is investigate effect addition Ash (OHA) on properties asphalt concrete mixtures. Marshall Test was perform mixture by OHA binder asphalt; different percentages (0, 5, 10, 15, 20%) volume were added binder. Five percent cements (5, 5.5, 6, 6.5 7%) weight limestone aggregate for preparing specimens find optimum content that could be Tests flow, stability, air void percentage mineral aggregate, retained stiffness, stiffness made. principle results filler Asphalt improves Stability, decrease with a 10%-15% olive husk ash replacement contribution pavement construction material field.
