Abstract

One of the main program of The East Java Province Government on the road sector is the capacity improvement through Road Reconstruction with Hardened Shoulder Project in the Strategic Corridor in the road province to accelerate the goods and people transport as a tools to support the public economic welfare. The benefit cost ratio analysis is carried out to evaluate how big the direct benefit which was obtained by the road users through this program. The research is conducted on the five main road which represent the urban and inter-urban area by comparing the two conditions, the base alternative (do nothing) and alternative (do something) to obtain the benefit influenced by the Road Reconstruction with Hardened Shoulder Project which fulfilling the economic feasibility criteria which is The Benefit Cost Ratio, Net Preset Value (NPV) and Internal Rate of Return (IRR).The Research shows that the first year benefit of the Road Reconstruction with Hardened Shoulder Project gives the Vehicle Operating Cost (VOC) saving by 4,86% and The Travel Time saving by 15,57%. The Benefit evaluation along 10 Years program is known from five roads which was studied only three had qualified to fulfill the feasibility criteria, B/C > 1, NPV> 1 dan Nilai IRR > r (discount rate 12 %) which was ranked based on the NPV/Capital value respectively Bts. Kab. Sumenep - Pantai Lumbang road by 5.425, Jajag - Simpang Lima Petahunan – Pasanggaran road by 1.429 and Kencong – Kasian road by 0.591.

Abstract

The valuation of Glendeng Bridge condition in Tuban District is needed to evaluate the deterioration of the bridge caused by the Bengawan Solo river flooding since the high rainfall which was made worst by the excavation of the bridge protection structure. This research is conducted through the direct visual survey by recorded the detail element of the bridge deterioration based on the deterioration code and assessed the level of severity and structural condition whether the element affecting the other element and suffering the overall bridge condition. This valuation of the bridge is based on the Bridge Management System (BMS) which was being studied by the Pusjatan Ministry of Public Work in 2012. The research shows that the main element deteriorated was the approach embankment, retaining wall, rubber bearing and earthquake dump isolator on the north side of Tuban caused by the drainage on the surface, excavation of the front of approach road and the flooding of Bengawan Solo river. The overall condition of the bridge is valuated with 4 (four) mark so that the bridge is needed to have the strengthening and replacement on the deteriorate elements

Abstract

The objective of this research is to utilize Reclaimed Asphalt Pavement (RAP) as a mixture of hot asphalt AC-WC type. The new additional material is required such as an aggregate and asphalt to meet the technical performance which is based on Specification Bina Marga 2018 Revision 2. This research is started by analyzing the RAP. The result of RAP extraction process are aggregates and asphalt. Grading on aggregate were conducted for required grading envelope. If it failed to qualify for required grading envelope, new aggregate and new asphalt is needed. Therefore, the AC-WC mixture was composed by mixing with a variation of RAP which is 10%, 20% and 30%. From all of the mixing composition, only mixture with 30% of RAP and 70% of new materials is recommended for hot mixture which fulfilling the engineering criteria requirements.

Abstract

Problems that often occur at level crossings with railroads are the high number of trafficaccidents, namely accidents between trains and vehicles, two-wheeled vehicles that fall dueto inadequate railroad infrastructure, and the condition of road pavements at level crossingsthat are not stable. This study is focused on handling pavement damage at railroadcrossings, especially at the JPL 67 location, which is located on the East Java Provinceroad, UPT area. Road and Bridge Management (PJJ) Surabaya, namely Jalan DepartemenKrian –Mojokerto Regency (link. 153) Km. 30. At the level crossing of JPL 67, two-wheeledmotor vehicle accidents often occur. There is a significant difference in elevation betweenthe highway and the railroad, causing damage to the pavement. The problem is tried to beovercome by conducting a study by UPT. PJJ Surabaya. This study aims to obtain the rightroad handling method according to the character of the load on level crossings, namelydynamic loads on train vibrations. Several road handlings trials have been carried out fromJanuary 2022 to June 2022, using several pavement materials. The study found that CTBwith a cement composition can make the pavement at level crossings last longer.
