Providing Sufficient Pavement Surface Friction (I.e., Skid Resistance) between Vehicle Tires and Pavement Surface throughout the Pavement Service Life is Considered to Be One of the Main Objectives of Highway Design. Moreover, Vehicle Safety, the Amount of Consumed Fuel, and the Wearing Rate of Vehicle Tires Generally Are Influenced by Pavement Surface Friction. in This Study, a Comprehensive Experimental Testing Program Was Conducted on Different Aggregate Sources, Including Calcined Bauxite and Five Alternative Local Sources, to Assess their Friction Characteristics. the Testing Program Included a British Pendulum Tester (BPT) and a Dynamic Friction Tester (DFT), Which Were Used to Evaluate …
