The area within 30 km of Abha and Khamis Mushayt in the Asir province of the Kingdom of Saudi Arabia is experiencing rapid growth and a corresponding strong demand for construction materials, including aggregate. The major source of aggregate at present is wadi gravels, supplemented by shallow pits in bedrock. A vast quantity of coarse aggregate as yet untouched is readily available near Abha and Khamis Mushayt in the granite, gabbro, and gneiss bedrock that underlie the area. Fine aggregate of high quality is readily available in the major wadis.
