Abstract

Road damage often occurs due to excessive volume of heavy vehicles so that vehicle loads cause strain and stress of the pavement layer. One way to improve the quality of asphalt mixtures is by adding PET plastic. Research was conducted to determine the effect of AC-BC mixtures with the addition of PET plastic waste as a binder additive in asphalt on Marshall parameters and Durability of Residual Strength Index. Based on the results of the study, the specific gravity of asphalt increased as the level of PET mixed increased. The penetration value decreases as the PET content increases because the asphalt becomes harder. Ductility decreases as more PET content makes the asphalt more brittle. The softening point value increases as the PET content increases because the wax content in the asphalt increases. In the durability test, the largest IKS value occurred in the mixture of asphalt penetration 60/70 + 4% PET at 94.58%; asphalt penetration 60/70 + 2% PET made an IKS value of 94.00%; asphalt penetration 60/70 + 3% PET made an IKS value of 94.36%; and asphalt penetration 60/70 + 0% PET had the smallest IKS value of 91.58%. All IKS values have met the minimum Bina Marga standard of 90%. Therefore, the greater the percentage of PET mixed, the greater the IKS value.

Abstract

Road damage is one of the problems caused by low material quality. The 2018 Bina Marga General Specifications have required material quality for asphalt mixtures, where good quality materials will produce pavement construction with high stability. This research aims to analyze the durability of the AC-BC (Asphalt Concrete-Binder Course) mixture using local materials from PT Sumber Batu Berkah, Tanjungan District, South Lampung Regency without additives based on the Marshall Testing Method. Based on the results of the research, it was found that the effect of soaking time variations of 0.5 hours, 24 hours, 168 hours, and 672 hours with a standard temperature of 60°C, the sample was soaked for a long time would make the stability and durability values smaller. Then obtained IKS value of 91.58% so it has met the minimum Bina Marga Standard of 90% and shows the longer soaking time, the smaller IKS value will obtained. Then for the IDP value is positive which means that the strength decreases by 0.44% during the soaking period so it meets the standard < 1%. And the IDK value of AC-BC mixture is 19.51 where the IDK value has decreased in strength by 19.51% during the soaking time. This is due to the decrease of stability value against the length time of soaking.

Abstract

The slowing down of vehicle speed that occurs on Jalan Diponegoro is caused by the behavior of vehicles that make intertwining movements (weaving). This condition causes vehicles traveling straight to reduce vehicle speed due to the presence of vehicles entering from Jalan Dr. Cipto Mangunkusumo towards Jalan Diponegoro. Queues that occur on Jalan Diponegoro cause a narrowing of the road, which can cause travel delays. The aim of this research is to analyze travel delays due to interwoven conflicts or weaving that happened on Jalan Diponegoro. This research was analyzed using the method gap acceptance. According to the results of data processing analysis and literature studies, the delay time was 23.28 seconds in the morning and 13.77 seconds in the afternoon for each 5 minute time interval. Key words: Travel Delay, InterwovenConflict, Gap Acceptance.
