The increase in traffic loads leads to premature damage in the form of cracks and deformation of the pavement. There are still many damaged roads before the service period ends. Efforts are being made to find alternative modifiers that can improve the quality of asphalt, but they are cheap and widely available in Indonesia. To solve the problem of road pavement damage and to help rubber farmers, natural rubber is used as a road pavement material to modify asphalt. Asphalt testing with the Marshall Test, using 4 variations of natural rubber content 0%, 6%, 6.5%, and 7%, for each natural rubber content, at least 3 test objects were made, so the total test object was 12 pieces. From the results of research that has been carried out on the effect of natural rubber as an added material on the pavement type LASTON AC-BC, the results of the study obtained Marshall characteristic test from 4 samples of the best natural rubber content, namely 7% with VIM value 4.58%, VMA 14.96 %, and VFA 69.53% and Marshall Stability (Stability) 1716.74 kg, yield value (Flow) 2.60 mm and Marshall Quotient (MQ) 654.16 kg/mm.
