Abstract

Material requirements for road pavement have increased along with major developments in Lampung Province. This causes the availability of aggregates to become thinner. One alternative replacement material is RAP (Reclaimed Asphalt Pavement). The aggregate in RAP becomes a potential that can be used as a basic material for road foundation layer. Therefore, research on the potential of RAP (Reclaimed Asphalt Pavement) if used as a base course material.This study uses RAP material obtained from the asphalt pavement layers on Soekarno-Hatta Street, Bandar Lampung.  The results of the maximum dry density value obtained from three behaviors amount of blow is 1.965 grams / cm3, so that the resulting CBR value is 51%. This is caused during mixing and blows, the added water cannot enter perfectly into the RAP cavity. Because RAP granules are coated with asphalt so it is impermeable. So it can be concluded that the potential RAP used in this study cannot be used in road foundation layer class A but can be used as a road fondation layer class S. And if an additional of blows are made in each layer, RAP potentially can be used as a class B road foundation material. Keywords : RAP (Reclaimed Asphalt Pavement), Base Course, Optimum Moisture Content.

Abstract

Transportation is a very important aspect to stimulate the economy, a region cannot be totally independent in meeting its own regional needs, so that the area needs other regions as a support where one of the connecting infrastructure is a toll road. The Terbanggi Besar - Pematang Panggang Toll Road is one of the 8 Trans Sumatra toll road projects that have entered the construction phase in 2017 which are planned to be operated in 2021. The tariff analysis carried out is based on the Ability to Pay (ATP) and Willigness to Pay (WTP) approach. The average ATP value obtained is Rp 131,638.00 / 100 km and the average WTP value obtained is Rp. 40,989.00 / 100 km. Respondent's ATP value > WTP value indicates that the ability to pay respondents is greater than willingness to pay because users have relatively high income but the utility of these services is relatively low. While the determination of ideal rates is based on the average value of ATP and WTP. Based on calculations, the price of the Terbanggi Besar - Pematang Panggang toll roads tariff is Rp. 86,314.00 / 100 km.

Abstract

Improving the Infrastructure development needs the soil that capable to support the load. It because soil is a material that major the role to support every construction. To identify a good soil is by doing physical and mechanical soil test. Soil compaction is process of increasing the soil density by reducing the particles proximity so it can reduce the air volume. Soil type is influencing to the maximum dry volume weight and optimum water content of that soil. Based on the soil type, compaction is divided into four types. In this research is using two types of compactions that are type A and Type C with purpose to find out the effect of soil particles diameter by passing sieve analysis to soil compaction using standard method.Compaction is done based on blow method and pressure method. In pressure method is using modification compaction tool with 5 Mpa, 10 Mpa, and 15 Mpa pressures.The result of this research is the blow method compaction type A has a higher water content than type C, but the value of maximum dry volume weight Type C higher than type A.  In pressure method it can be concluded that as the higher pressure so the water content and the maximum dry volume weight are also getting higher.Keyword:Soil Particles, Standard Method of Compaction, Blow Method and Pressure Method Compaction

Abstract

The safety level of a slope is influenced by several factors, including factors tilt and loads working on it. Slope conditions with large loads and steep slopes can cause landslides. The influence of heavy rain flushed the majority of the region martapura - baturaja cause landslides and slope at some point in double track train along 50m which have geographic condition consists of the land pile of high steep, so prone to landslides. This is certainly very dangerous for trains, and around the slopes a solution is needed that can be an alternative to make the slope safe from landslide hazards. Based on the laboratory tests that have been carried out of the samples were taken from the site, so the analysis of the existing slopes stability with computer analysis shows the condition of unstable because from the result of numerical safety value analysis 1,731 for condition 1 and 1,732 for condition 2, so that needed reinforcement on the slopes itself. From the analysis of the slopes stability which has been strengthened with a combination of retaining Wall of land and drill pile using the Computer Analysis obtained greater numerical safety value compared by only reinforced with retaining Wall land for 3,978 to condition 1 and 3,983 to condition 2, so the design of strengthening is safe and able to withstand landslide. Keyword : Borehole Data, Geoelectric, Computer Analysis using methods Fellenius
