This report describes a laboratory evaluation of three asphaltic concrete, plant produced mixtures containing Asphadur. The mixtures represent a type A asphaltic concrete and two type B asphaltic concretes. The type A and one of the type B mixtures were used in pavements and will be evaluated later for durability and serviceability. The second type B mixture was made only for laboratory testing. In each instance, control batches of the same mixtures but without Asphadur were made for comparison. Type A is a high type asphaltic concrete, requires a minimum of 65 percent crushed particles and is generally used for higher traffic volume roads. Type B is used for intermediate or lower traffic volumes and requires a minimum of 30 percent crushed particles.
