N2 - Bituminous aggregates from a total of 52 sources located in Texas, Oklahoma, Arkansas, New Mexico, and Missouri were evaluated using both Micro-Deval and magnesium sulfate soundness tests. Each aggregate was also characterized using petrography, absorption, and specific gravity. Findings showed that Micro-Deval test is a more repeatable test than the soundness test. Micro-Deval showed a fair to good correlation with soundness and an improved correlation was observed when used along with aggregate absorption values. It is concluded that further research is needed to completely replace soundness tests but the Micro-Deval test could be used as a good quality indicator tool.
