Abstract

Tire rubber is a material derived from vehicle tires that are no longer used. Vehicle tires are made from a mixture of natural and synthetic rubber reinforced with fibers and steel. After their useful life is over, tires are difficult to manage because they do not biodegrade easily. The positive properties of tire rubber are that it is waterproof, has good flexibility and flexural properties. Therefore, this research also aims to analyze the effect of tire rubber addition in AC-BC liquid asphalt mixture on Marshall test. This research method involves AC-BC type liquid asphalt mixtures with tire rubber percentage (0%, 0.5%, 0.75%, 1%, and 1.25%). The mixes were then tested using the Marshall test to evaluate stability, flow, Marshall value as well as VIM, VFA, and VMA values. The Marshall test results were statistically analyzed to identify significant differences between mixtures with and without the addition of tire rubber. The results of this study obtained an optimum asphalt content value of 5.25%. In this study, the greater the percentage addition of tire rubber, the VFA value increases, but the VIM and VMA values decrease. Stability values in the addition of tire rubber from lowest to highest are 1663.12 Kg, 1821.86 Kg, 1904.84 Kg, 1998.63 Kg, and 2005.85 Kg. Despite the increase, the stability value still meets the specification standards. The flow value has increased, but at a percentage of 1% and 1.25% it does not meet the specification standards. The Marshall Quotient value decreased at a percentage of 0.75% to 1.25% although it still met the specification standards. Thus, it can be concluded that the use of rubber tires in AC-BC liquid asphalt mixtures has a positive impact on Marshall test results, especially in variations of 0.5% and 0.75%.
