Abstract:

The study considers the chemistry of petroleum asphalt at the molecular and intermolecular levels. Thousands of molecular species exist within any particular asphalt. The polarity among asphalt molecules varies widely and the physical properties are governed by the balances of polars and nonpolar components. Several speculations on the effects of chemical composition on pavement performance are offered. In general, the mechanical or structural properties of asphalt are related to the intermolecular structuring among the polars. This report describes the current status of the Strategic Highway Research Program chemical studies of petroleum asphalt. It is intended to be instructive to the non-chemist, and is a speculative effort to correlate some of the known chemical properties of asphalts with pavement performance characteristics.
