Abstract
This research aimed to determine the stability value of modified asphalt using a cyclic natural rubber. Modified asphalt designed with mixing with the pure bitumen with cyclic natural rubber. The increasing of cyclic natural rubber on a mixture of bitumen started from 0 phr, 1 phr, 3 phr, and 4 phr. Furthermore, modified bitumen (5 samples) tested with testing property requirements test of pure asphalt. The results obtained that the data qualified for property requirements for asphalt. The next step was making a specimen with mixing the modified bitumen, soft aggregate and coarse aggregate to optimum asphalt content of 6 %. Then the specimen tested with Marshall Test to determine the value of bitumen stability. Then the result of stability value from sample 1 to 5 was 1252 kg, 1129 kg, 1159 kg, 1312, and 1320 kg respectively. Based on the results, the conclusion of this research was cyclic natural rubber could be used as a material to modified asphalt as well as increased the value of asphalt stability. The increasing of stability value meant that highway could hold a heavier load.
