1 Case Studies on Achieving Significant Development in Rural Road Project Dated : Presented By: Mahesh Hiremath, Chief Operating Officer, K.R.R.D.A, Bangalore

2 1. PROFILE: Roads play major role in Rural development Important sectors like Agriculture, Electrification, Water supply & sanitation, Health and Road are still under process of development in India, especially in rural areas. These roads are either Track or Earthen having road width of about 11 links (8 feet) & at the most 22 links (16 feet) only.

3 ROLE & IMPORTANCE OF RURAL ROADS DEVELOPMENT Connectivity for Poverty reduction strategy. Good passenger transport facility, good accessibility to all sphere of life i.e better education, Health, better marketing facilities for agriculture development, goods transportation Integration with higher category of roads.

4 3. PLANNING & RURAL ROAD STATISTICAL DETAILS i. Block wise (DRRP) rural road plans prepared. ii. iii. iv. Roads developed & improved for connectivity, up gradation of rural roads done in NABARD, PMGSY, NGNRY & in other State funding schemes. Rural Road connectivity is proposed to be carried by improving the link Roads, MRL & upgradation of Roads (CUCPL). Periodical inventory & updation of the existing rural road net work district & block wise

7 Process of Development of Rural Roads 1. Rural roads developed under various schemes 2. DPRs prepared based on IRC, MORD, SP- 20, 72 & The conventional way of improvement of Rural roads is of Construction of embankment, Structural base i.e G.S.B, WBM G-II & G-III and providing PMC as a surface course. 4. In the process of developing rural roads much emphasis is given to use of local material (Marginal Materials). 5. Different Innovative technology methods are also adopted giving importance to R&D in constn. of rural roads.
