The increased traffic load encourages premature damage to the pavement. The damage is in the form of potholes, cracks, waves, and deformation of the road pavement. The elastomer content in natural rubber can be used as an asphalt modification material. Indonesia is one of the largest rubber producers in the world. From the results of research that has been done, natural rubber can increase the characteristic value of asphalt concrete mixtures. Stability, flow, VIM, VMA, and VFA values have increased. But the value of the Marshall Quotient has decreased.
