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

Porous asphalt is one of the asphalt mixtures being developed for wearing course construction. This layer uses open graded which is dominated by coarse aggregate, resulting in quite large voids. The material used in this study came from Lampung. The purpose of this study was to determine the characteristics of porous asphalt mixtures using materials from Lampung. The results of the aggregate testing show that aggregates originating from Lampung are able to meet the general specifications of Bina Marga in 2018. This study shows that the highest stability is found at 5.5% asphalt content with a stability value of 552.52 kg and the lowest stability at 6.5 asphalt content % with a stability value of 459.22 kg. The lowest flow value is found at 5% asphalt content, which is 5 mm, while the highest flow value is found at 6.5% asphalt content, which is 6.2 mm. The highest VIM was found at 4.5% asphalt content which was 21.77%, while the lowest VIM value was found at 6.5% asphalt content which was 14.07%. The highest cantabro loss value was found at 4.5% asphalt content, which was 39.11%, while the lowest cantabro loss value was found at 6.5% asphalt content, which was 13.91%. The lowest asphalt flow down value is found at 4.5% asphalt content, which is 0.16%, while the highest AFD value is found at 6.5% asphalt content, which is 1.30%. Based on the test specimens for the optimum asphalt content, the permeability coefficient value was 0.075 cm/second.

Abstract

Porous asphalt is an asphalt mixture that has a high pore space, therefore it is necessary to use asphalt modification which is expected to increase the stability of porous asphalt, so that porous asphalt is expected to have better performance. Plastic waste can open up opportunities to be used in the field of highway construction because it is easy to obtain and the price is more economical as a porous asphalt mixture. Referring to this, a research was carried out on the durability of porous asphalt mixtures with polyethylene terephthalate (PET) plastic waste as an additive to asphalt. The purpose of this study was to determine the effect of using PET plastic waste on the durability of porous asphalt mixtures. The method used is a laboratory scale experimental method based on 3 types of testing, namely marshall, cantabro loss and asphalt flow down. The gradation in this study used the Australian Asphalt Pavement Association (AAPA) 2004 open graded. The test results showed successively the immersion effect of porous asphalt with the addition of 0%, 5% and 7.5% PET plastic resulted in a decrease in the IDP value (Index Durability First) of 1.25%, 0.89% and 0.83% , and also a decrease in the value of IDK (Second Durability Index) based on the value of loss of strength of 44.12%, 33.31% and 30.52%. This shows that porous asphalt mixed with PET plastic has better durability than without PET.

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.

Abstract

As the capital city of Lampung Province, traffic density in Bandar Lampung City cannot be avoided. Due to the density of existing traffic flow, transportation facilities need to be improved. Transportation facilities improve can be done with many examples of traffic engineering, like make an intersections, roundabout, underpasses, flyovers, etc.  In the Pramuka traffic area, the government took the decision to make a fly over. The construction of fly over Pramuka – Indra Bangsawan impressed not pay attention to the applicable geometric standard of urban roads, so it needs to be evaluated to find out the safe speed to cross on it. The research method is by first searching for the ideal radius length after that searching for the ideal arch length which will be compared with the existing arch length.  The result, a safe passing speed when crossing the fly over is 18 km / h (full circle) and 16 km / h (spiral-spiral), and at the cross over fly over is 12 km / h (full circle) and 8 km / h (spiral-spiral). Speed requirements for urban road plans are 30 - 50 km / h, so it can be concluded that the construction of fly-over pramuka - indra bangsawan has not met the applicable urban road planning standards.
