Abstract

Plastic waste, which is one of the biggest environmental pollutants, can open up opportunities to be utilized in the field of highway construction because it is easy to obtain and has a more economical price as a porous asphalt mixture. Referring to this, a research was carried out on the characteristics of a mixture of porous asphalt with polyethylene terephthalate (PET) plastic waste as an additive to asphalt. The purpose of this study was to determine the effect of the use of PET plastic waste on the characteristics 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 open graded Australian Asphalt Pavement Association (AAPA) 2004. The test results showed that the addition of PET could improve the performance of porous asphalt mixtures. Stability, density, MQ, and VFA values increase with the addition of PET content so that they can prevent fractures due to traffic loads. The decrease in the cantabro loss value makes the mixture's resistance to disintegration better. addition of PET content up to 7.5% can reduce the flow value so that the mixture has optimal flexibility. However, the recommended PET content should be below 5% because in this study the penetration and ductility values did not meet the general specifications for 2018 Highways.

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

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 Pesawaran Regency has a strategic value in increasing the regional development of Lampung province. Regional development aims to improve regional welfare by utilizing all available resources so that whole community gets the maximum benefit. There are indicators that can help develop the territory of a district, namely the availability of infrastructure and road network systems in the region. In order to improve road network infrastructure, a method is needed, namely by setting priorities because the large number of road sections in Pesawaran Regency can result in limited time, costs, manpower, and resources in improving the quality of road network infrastructure. In this study, the Analytical Hierarchy Process (AHP) method was used as a determinant of priority order with the criteria used, namely road conditions, accessibility, mobility, public service infrastructure, and regional development. From the results of the calculations and analysis that has been carried out, it is found that the main criteria that determine priorities are road condition criteria (45,52%), in addition there are accessibility criteria (22,06%), mobility criteria (13,64%), public service infrastructure criteria (10,32%), and regional development criteria (8,46%). The order of priority for the improvement of the Pesawaran Regency road sections includes Kubu Batu - Kota Jawa, Pasar Baru - Gunung Sari, Penengahan - Gunung Sari, Kubu Batu - Lubuk Tanah, Tegineneng - Tri Rahayu, Sidodadi - Pringsewu Boundary, Way Harong - Sukamandi, Wiyono - Way Brulu, Wates - Sumber Jaya, Guyuban - Pringsewu Boundary. Key words : Regional Development, Priority, Analytical Hierarchy Process Abstrak Kabupaten Pesawaran memiliki nilai strategis dalam meningkatkan pengembangan wilayah provinsi Lampung.
