PHYSICOCHEMICAL STUDIES OF "TENDER-MIX" AND "NONTENDER-MIX" ASPHALTS

Eight Federal Highway Administration-supplied asphalts, which have established field-performance histories relative to "tender-mix" pavements, were examined by three physicochemical methods. The purpose of the study was to elucidate some fundamental differences between the "nontender" and "tender-mix" asphalts. Heat-of-immersion measurements and resilient deformation measurements showed reasonable correlations with "tender-mix" pavements, while percent n-hexane asphaltenes and their infrared spectra did not.
