CHEMICAL MODIFIERS TO IMPROVE THE STRENGTH AND DURABILITY OF ASPHALT CONCRETE

The purpose of this paper is to discuss the value of chemical modifiers as a means of improving the physical properties and durability of asphalt concrete. A review of the factors that adversely affect the integrity and durability of asphalt concrete pavements is included. The ability of several different types of chemical modifiers to improve the properties and durability of asphalt concretes is illustrated by test data on laboratory and field specimens with and without chemical modifiers. Liquid chemical modifiers appear to provide a practical means of improving the strength, age-hardening resistance, water resistance, and overall integrity of asphalt concrete pavements.
