Abstract

The construction of the South Sumatra Light Rail Transit (LRT) requires a huge development cost, besides that it has quite a large annual operational and maintenance cost. In order for South Sumatra LRT maintenance costs to run efficiently and effectively, it is necessary to optimize maintenance costs for South Sumatra LRT facilities and infrastructure based on Life Cycle Cost Analysis. Life Cycle Cost is an economic analysis method that refers to all costs associated with development, operating and maintaining a construction project over a certain period of time (Heralova, 2017). The research objectives were to analyze the physical condition of Facilities and Infrastructure South Sumatra LRT, evaluate South Sumatra LRT maintenance strategies and develop maintenance cost scenarios based on Life Cycle Cost. Based on data processing using the combined condition index method, the total value of the South Sumatra LRT infrastructure components reached 5,718. The physical condition of the South Sumatra LRT infrastructure reviewed is on a good scale with minor damage so that the option of preventive or time-based maintenance activities can be used. For the Life Cycle Cost of South Sumatra LRT infrastructure, the value obtained is IDR 2,080,482,508,541,480.

Abstract

One causes of construction failure on flexible pavement is changed composition of the aggregate gradation in asphalt mixture of the plan due to mechanical or non-mechanical process. Aggregates can occur degradation, ie gradation changes due to aggregate breakage of grains. Aggregate degradation can be caused by both mechanical and chemical processes. The decrease in quality occurring in the asphalt mixture is thought to be due to the aggregate gradation change in the asphalt mixture. To find this out, a study on the degradation level of flexible pavement construction is conducted,from Asphalt Mixing Plant to overlay location. Used mixture are Asphalt Concrete-Wearing Course produced by PT. Manggung Polah Raya for location on Sultan Agung Street, Bandar Lampung, Lampung and PT. Rindang Tigasatu Pratama for location on Teuku Cik Ditiro Street, Bandar Lampung, Lampung. Test of samples performed are extraction test and sieves analysis test. From the research result, it is founded that there is degradation during transport of asphalt mixture from Asphalt Mixing Plant to the location. Average degradation percent of location I, location II and location III PT. Manggung Polah Raya and PT. Rindang Tigasatu Pratama is %CA decreased by 5.17%, %FA increased by 3.67% and %filler increased 1.50%. Factors affecting degradation are due to work execution, specific gravity of aggregate and time of transport.Keywords: Road Pavement, Asphalt Concrete, Degradation
