Abstract

This study focuses on comparing the engineering characteristics of asphalt concrete mixtures using Hydrated Lime (HL) and Ordinary Portland Cement (OPC) as mineral fillers to improve the performance of asphalt concrete mixtures. The fundamental engineering properties of the mixtures were determined through the Marshall mix design ,whilst the performance properties were determined through the Wheel Tracking and Dynamic Creep Test. The results of the laboratory investigation would reveal the advantages of using these materials as filler. The smaller particle size as well as the irregular shape of the HL as shown by the Scanning Electron Microscopy (SEM) test contributed to good interlocking of the aggregates in the mixtures. This was not observed in mixtures with OPC filler which displayed a spherical particle shape. The X-Ray Diffraction (XRD) test revealed that the HL particle had higher capacity to diffract the rays, denoting that it is a stronger material particle than the OPC. The Wheel Tracking test results showed that HL mixtures undergo less deformation than then OPC mixtures. A similar trend was observed in the Dynamic Creep Test.
