Effect of asphalt mixture compaction on stability and Volumetric properties of ACW14

Abstract

This paper investigates the influence of Marshall Compaction (50 and 70 blows) on the Stability and Volumetric Properties of ACW14 asphaltic concrete mixes. The samples were prepared according Marshall Mix design method. The properties studied were resilient modulus, air voids, bulk density and stability. The results of this study indicate that 75 compaction yield the highest Marshall Stability value and lower bitumen content. The study concluded that mixtures subjected to 75 compaction blows show better performance than the mixtures subjected to 50 blows.
