Investigation of Asphalt Additives
The overall objectives of the research were to (1) identify through laboratory testing, the most promising types of additives or admixtures for reducing rutting and cracking in hot-mixed asphalt pavements, (2) develop guidelines showing how the additives can be incorporated into actual pavements and (3) develop procedures for evaluating additives. Additives selected for evaluation included latex, block copolymer rubber, ethylene vinylacetate, polyethylene, and carbon black. The additives were combined with asphalt cements from two sources with widely differing chemical composition and rheological properties. Asphalts two grades softer than that normally used in hot-mixed asphalt concrete were used with the additives. All additives demonstrated the ability to substantially alter the temperature susceptibility of asphalt concrete mixtures.
