AbstractIn this report a relationship is established between the variables of compaction temperature, compaction effort, mixture gradation and, density, air void content and stability of asphalt mixtures. The Marshall method of mix design was used, and Vibratory Kneading Compactor was utilized for compaction. Results include Marshall Stability and density-air void analysis for 4 and 6-inch specimens. It was found that the densities generally increased with increase of compaction temperatures and compaction efforts. From selected sets of 6-inch specimens, 4-inch cores were obtained. Density and stability studies were carried out on these cores and the results obtained were found to have the same trends. The air void content and voids in the mineral aggregates decreased with the increase of compaction effort. Stability increased with the increase in density. All the results found, indicate strong effects of compaction temperature and compactive effort on the amount of air voids, VMA, density, and stability of the mixes used.
