GOVERNMENT OF THE PEOPLE’S REPUBLIC OF BANGLADESH ROADS AND HIGHWAYS DEPARTMENT ROAD TRANSPORT AND HIGHWAYS DIVISION MINISTRY OF ROAD TRANSPORT AND BRIDGES Maintenance and Rehabilitation Needs Report of 2018 - 2019 for RHD Paved Roads HDM Circle May 2018 PREFACE This is the 2018-19 edition of Maintenance and Rehabilitation Needs Report prepared from the output of HDM-4 Analysis. The RMMS database and the HDM-4 model have been utilized to derive yearly maintenance demand for RHD. During 2016-17 HDM Circle conducted comprehensive survey which included Pavement Inventory in two National Corridor Road N1 and N3 and Road Condition Assessment in all RHD Road Network. Traffic Survey was carried out at around 1300 stations. The RMMS Database was updated accordingly and was used as an input for this year’s HDM Analysis. By the HDM Analysis, the time and location of maintenance requirement for the RHD Road network has been identified and prioritized in accordance with NPV/Cost ratio. Socio-economic and political factors, not considered in this analysis, are extremely important in prioritizing maintenance treatments. It is expected that this approach will be adopted in future years. The list of on-going projects has been prepared after collecting those from Division and Project Offices of the foreign aided projects. Projects, which are in progress and not completed before the start of Roughness Survey have been kept out of the HDM analysis to avoid duplication in the maintenance program and to find out actual immediate demands. However, few segments already completed or ongoing may appear in the HDM output because those were not reported by the field offices before the HDM run and hence were not excluded. Finally, the officers of HDM Circle must be appreciated for their relentless effort in publishing this report. I would also like to extend heartfelt appreciation to the Officers of RHD Field Divisions for their cooperation during the data collection phase. Superintending Engineer HDM Circle Roads & Highways Department Sarak Bhaban, Tejgaon, Dhaka-1208 Executive Summary The Highway Development and Management (HDM-4) Model (HDM-4 software), mainly an economic tool, has been used to project the total maintenance need of RHD Road network and also to select and prioritize maintenance work on the basis of NPV/Cost ratio. For this purpose, the analysis has been carried out in the two sequences. Firstly, all roads have been analyzed to assess the overall long-term maintenance need of the RHD road network. The overall maintenance needs has been found to be 162962.38 million taka for the year 2018-19, 40053.33 million taka for 2019-20, 24974.27 million taka for 2020-21, 19423.16 million taka for 2021-22 and 15777.01 million taka for the year 2022-23. It is evident from the analysis that, investment needs tend to decrease considerably provided that the 1st year’s requirements are met completely. So, efforts should be given to maximize the 1st year’s maintenance works in order to minimize backlogs. Secondly ongoing projects, which are in progress and were not completed before the start of Roughness survey, have been excluded from the HDM run to project the immediate maintenance requirement and it has been projected to be 118841.53 million taka. Since the prioritization of projects using NPV/Cost favors the more highly trafficked roads, they will not have priority for maintenance and rehabilitation works due to their low traffic volume. So, a separate prioritization process is adopted for the recovery of zilla roads as suggested by the Road Master Plan. Table of Content Sl. No. Content Page no.

Proper maintenance and management of these assets is a funda- mental requirement which is vital to the national economy. For optimization of the fund disbursement RHD has been using the Highway Development and Management Model (HDM-4 Software) an eco- nomic tool since 1999-2000. Since then, a Road Maintenance and Rehabilitation Needs Report (MRNR) is published every year to asses 5-year investment plan to meet acceptable levels of service provision for the RHD road network. The current Maintenance and Rehabilitation Needs Report of 2018-19 is a continuation of the process. RHD paved roads have been analysed to assess the overall long-term maintenance need of the RHD road network. Ongoing projects have been excluded from the HDM analysis to project the immediate maintenance requirement. However few segments either completed or ongoing may appear in the HDM outputs because they were not reported by the field offices before the HDM analysis. The outputs from HDM-4 are based on the Road Maintenance and Management System (RMMS) da- tabase of RHD. This report provides recommendations for Engineers in RHD to improve the road network in a cost effective manner. 1.2 Objectives of the analysis: The main objectives of this analysis are: To project the total maintenance need of RHD Road network. To select and prioritize the maintenance works based on NPV over financial cost ratio. To develop a 5-year investment plan to meet acceptable levels of service provision for the RHD network. To provide a database for preparing RAMS map that combines all relevant information and shows decision makers where they can most effectively allocate funds for maintenance and rehabilitation. To provide recommendations for Engineers in RHD to improve the road network in a cost ef- fective manner. 1.3 Methodology: Data required for the analysis are mainly primary in nature and obtained from field survey method. 1.3.1 The Data of RMMS Database: The data of RMMS database is the fundamental input to HDM 4 analysis. In 2004 RHD undertook a major survey of its network covering around 15,000 km of roads.
