RELATION OF ASPHALT CHEMISTRY TO PHYSICAL PROPERTIES AND SPECIFICATIONS

This paper is a synthesis of information concerning the chemical composition of asphalt and the relation of such composition to the physical properties of the asphalt and its performance as a binder in asphaltic pavements. The data presented and relationships discussed demonstrate that there is no simple "cook book" approach to specifying the characteristics of asphalt cements that will guarantee trouble-free mixtures with all types of aggregates.
