Publisher Summary This chapter examines the literature dealing with the chemical composition of asphalt and changes in composition during environmental aging that affect durability-related properties. The characterization of the chemical functional types gives a fundamental approach to the relationships between asphalt composition and asphalt properties, and the performance of asphalts and asphalt-aggregate mixtures. Differences in the quality of asphalts depend on their crude oil sources because different crude oils have different chemical compositions. A durable asphalt is defined as one that (a) possesses the physical properties necessary to produce the desired initial product performance properties, and (b) is resistant to changes in physical properties during long-term, in-service environmental aging. Durability is determined by the physical properties of the asphalt, which are determined directly by chemical composition.
