The Purwodadi - Nongkojajar road section is one of the East Java Province roads in UPT PJJ Probolinggo, which received funding from the Regional Road Grant Program (PHJD). From the results of the road condition survey in 2020, the condition of road damage in the form of holes and hair cracks was obtained. Based on this, it was necessary planning the thickness of the re-pavement or overlay. This program begins with inventory and road condition, topographic and soil investigation surveys. From the results of the topographic survey, we can measure the slope, then we conduct an investigative survey using Benkelman-beam deflection measure tool to determine the back- deflection value. References and secondary data of traffic growth and road class data are collected. The thickness of the pavement was calculated using the MDP 2017 method. This research found that the required layer was AC-WC layer with an expected thickness of 4 cm. Due to the uneven condition of the existing road, an additional leveling layer AC-BC was needed to overcome this condition with a thickness of 3.0 cm.
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
The Puspa Agro central business market was built to increase the food supply as well as shortened the supply chain to elevate the farmer income and in the large scale escalating the economic growth of East Java Province. Meanwhile, the central market operational activity did not work as expected as planned and the government initiates to upgrading the accessibility toward the Puspa Agro central market by constructing a new road connecting with the toll road directly the arterial road. The main purpose of this research is to evaluate the location of Puspa Agro central business market using the center gravity model. The research shows that the location of Puspa Agro central business market is not fulfilling the requirement based on the 3 (three) approach which are the location of people an d goods mobility, the location of agriculture production such as, fishery, fruit and vegetables and the number of the population of the nearest city. The three alternates location is proposed, at Waru and Candi districts in Sidoarjo City and near the Pasuruan City. The alternate location must be considered to rise the central business market income since the existing location was not fully capable to achieve the trading transaction.
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.
