- Abstract
Road pavements in Indonesia often uses a mixture of Asphalt Concrete (AC) and Hot Rolled Sheet (HRS), which frequently occur premature damage to the pavement caused by extreme climate change, and also rapid development of land transportation causing increased loads on the pavement, causing queues of vehicles that make traffic jams. Over loading that is too long due to queuing of vehicles causes the performance of the asphalt to decrease. To improve and repair the performance of the asphalt, additives were added, namely Styrene Butadiene Styrene (SBS) polymer and Ethylene Vinyl Acetate (EVA) polymer into a mixture of Asphalt Concrete-Wearing Course (AC-WC) and Hot Rolled Sheet-Wearing Course (HRS-WC) using Marshall Method Test, Marshall Immersion Test and Cantabro Test. This research method is in the form of laboratory experiments with material testing and direct observation. Based on the General Specifications of Bina Marga Division 6 Revision 1 of 2018 for Marshall Tests Parameters, the best stability value for the Asphalt Concrete-Wearing Course (AC-WC) was obtained with the addition of SBS polymer rather than other mix. The Index of Retained Strength (IRS) results from the Marshall Immersion test have met the requirements greater than 90%. The percent of Weight loss from the Cantabro Test has met the requirements of less than 20%. Based on the two tests that have been carried out, sample of SBS modified asphalt mixture is better than the standard asphalt mixture and EVA modified asphalt mixture. The test specimen for the mixture of SBS modified asphalt AC-WC produces the highest Index of Retained Strength value, which is 93.33% compared to the test specimen for the mixture of standard asphalt AC-WC at 92.37% and the mixture for EVA modified asphalt AC-WC at 92.74%. The test specimen of SBS modified asphalt HRS-WC mixture also produced the highest Index of Retained Strength of 91.48% compared to the standard asphalt HRS-WC mixture test specimen of 90.25% and EVA modified asphalt HRS-WC of 90.58%. On Weight Loss, the specimens of standard asphalt AC-WC mixture are 4.04%, SBS modified AC-WC asphalt mixtures are 3.14%, and EVA modified AC-WC asphalt mixtures are 3.57%. The SBS modified AC-WC asphalt mixture was better Weight Loss than the standard AC-WC mixture and the EVA modified AC-WC mixture. On Weight Loss, the specimen of standard asphalt HRS-WC mixture was 3.91%, SBS modified asphalt HRS-WC mixture was 2.86%, and EVA modified asphalt HRS-WC mixture was 3.34%. The SBS modified asphalt HRS-WC mixture performed better Weight Loss than the standard asphalt HRS-WC mixture and the EVA modified asphalt HR-WC mixture.
