The objectives of this Stone Matrix Asphalt (SMA) study were to: (1) find the interlaboratory average values and the standard deviations of voids in mineral aggregates (VMA), theoretical maximum density and optimum asphalt content; (2) develop a draindown test and evaluate the effects of various factors on draindown of asphalt in SMA mixes; (3) develop a comparison of laboratory densities of SMA mixes prepared by a gyratory machine to those prepared by the mechanical Marshal hammer; and (4) develop a method to evaluate stone-on-stone contact in SMA mixes.
