To determine the maximum density line that would best predict the voids in the mineral aggregate (VMA) of a mix, 101 mix designs were analyzed. The line drawn from the origin to the actual percent passing the nominal maximum aggregate size provided the best correlation with the measured VMA of the mixes. Differences between mix gradation and the maximum density line at the 2.36-mm (No. 8) sieve size and finer gave the best prediction of the VMA of a mix. Additionally, 24 laboratory mix designs were evaluated to determine the effect on the VMA of a mix of four variables considered important in obtaining VMA: gradation, quantity of aggregate <75 microns [passing the 75 micron (No. 200) sieve], size distribution of aggregate <75 microns, and the angularity of the fine aggregate. Gradation provided the largest changes in VMA for all mixes. The quantity and size of aggregate <75 microns caused significant changes to VMA, especially for the finer gradations. The angularity of the fine aggregate caused significant changes to mix VMA, especially for the coarser gradations.
