Performance evaluation of pre-vulcanised rubber latex modified asphalt concrete with various aggregates
Natural rubber effectively strengthens asphalt cement's crucial properties. This study aims to examine the mechanical properties of asphalt concretes modified with pre-vulcanized natural rubber using different aggregates available in Thailand (limestone, granite, and basalt). The impact of pre-vulcanized natural rubber is evaluated in terms of the dry rubber content to asphalt cement ratios (0%, 3%, 5%, 7%, 9%, 11%, 13%, and 15% by the total weight of asphalt cement). The pre-vulcanized natural rubber improved mechanical properties by enhancing bonding between rubber and asphalt cement molecules. The highest performances were found at the optimum ratio of 3% for all the studied aggregates. At this ratio, Marshall stability improved by 16.09% for basalt, 4.79% for granite, and 9.43% for limestone. Indirect tensile strength increased by 18.33%, 6.97%, and 10.22%, and the resilient modulus improved by 55.29%, 25.40%, and 39.66%, and fatigue life was enhanced by an average of 34.9, 20.1, and 24.4% for the respective aggregates. The rut depth decreased significantly by 30% for basalt, 72% for granite, and 44% for limestone. Basalt and limestone, having alkaline characteristics, showed better co-adhesion with natural rubber than granite. The proposed fatigue distress model revealed a logarithmic relationship, independent of the rubber-to-asphalt ratio or aggregate type.
