Abstract

The base course material uses mountain stone which is broken up with a stone crusher so that it has a high quality which makes it expensive. In this research we need an alternative material to replace fine aggregate that meets the specification requirements. One of the more affordable resources is sand aggregate. The purpose of this study was to determine the density and comparison of the California Bearing Ratio (CBR) value of the base course using sand as a substitute for fine aggregate. The method used in this research is laboratory scale testing to obtain data on aggregate characteristics, optimum moisture content, and CBR values. The base course aggregate mixture used was 55% coarse aggregate and 45% fine aggregate consisting of a mixture of fine crushed stone and 0%, 10%, and 20% sand substitution. The results showed that the KAO value decreased with the addition of sand aggregate. Laboratory CBR values increased with 0% sand substitution having a CBR value of 99.2%, 10% sand substitution having a CBR value of 90.6%, and 20% sand substitution having a CBR value of 84.1%. Only the laboratory CBR value with sand substitution of 20% does not meet the specifications for base A aggregate, namely a minimum value of 90%.

Abstract

A level crossing is a form of an intersection where a railway line crosses a highway at the same level. This may result a long queue which is caused by changes in velocity and density of vehicles. Hence, research should be conducted in order to determine changes in vehicle velocity which occurs when the gated crossing is opened on that road section. One of the level crossings between the railway line and the highway can be found on Jalan Hos Cokroaminoto, Kebon Jahe, Tanjung Karang. This study aims to determine changes in traffic velocity that occur on Jalan Hos Cokroaminoto based on the equivalent of light vehicle (EKR) value obtained from the headway ratio method. The results of the observation show that the average velocity of vehicle when crossing the railway line is 3.12 km/hour, while when entering the crossing is 19.48 km/hour so that there is a decrease in velocity in the amount of 16.36 km/hour.Keywords: Shock Wave, Light Vehicle Equivalence (EKR), Rasio Headway Method, Greenberg Method

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.
