ASPHALT EMULSION TREATED AGGREGATES. PART 1. LABORATORY EVALUATION

This report is concerned with the development of a testing procedure for the laboratory evaluation of granular soils mixed with asphalt emulsions for use in pavements. The specific topics investigated or discussed for use in Arizona are aspects of mixing, compaction, and strength testing of the asphalt-emulsion mixtures. Data are presented to show the effects of mixing water, emulsion content, and soaking of specimens on the density, R-value, stability and cohesiometer value of aggregates compacted with the Triaxial Institute kneading compactor. The principal benefit or improvement from the use of the emulsion is shown to be on the cohesiometer value for mixtures prepared and tested at ambient temperature. Additional comparisons are made with specimens prepared and tested at other temperatures with the emulsion and also with the base asphalt cement of the emulsion. A procedure for the laboratory evaluation of emulsion-aggregate mixtures is presented.
