This article presents the state of the highways in the Republic of Iraq and studying the possibility of using the regeneration technology of asphalt concrete as a base for road pavements strengthen. This technology has not yet used in Iraq. Therefore it proposed to use for the maintenance and reconstruction of roads the technology of cold regeneration of asphalt concrete in the asphalt plant, which ensures the improvement of the properties of asphalt granules due to its preliminary crushing, the introduction of cement additives as a mineral binder. Compositions of asphalt-granular-concrete mixtures have developed, and data from studies of the properties of asphalt-granular-concrete of various documents presented. The most common pavement defects in Iraq are plastic deformations, which are caused by a combination of high temperatures and low strength characteristics of asphalt concrete. Pregame compositions used to strengthen the construction of road pavements with increased strength and shear stability. A cost-effectiveness calculation of using the cold technique is also presented moreover compare the cost this application in Russia and Iraq also.
