This report presents the results of a laboratory study that compared well-graded and gap-graded aggregates used in asphalt concrete paving mixtures. There was a total of 424 batches of asphalt concrete mixtures involving 3,960 Marshall and Hveem specimens and 33 gradations of which 27 were gapped. Comparisons are made of the maximum densities for each gradation determined from unit weight-asphalt content plots within each series, the maximum Marshall stability (determined from stability versus percentage of asphalt plots) of various gradings within each series and between series, and the Hveem stability at 3 percent air void content for each grading within each series.
