He informed that the soil can be stabilized using a. Lime b. Cement c. Fly ash d. Granulated blast furnace slag e. Combination of above f. Several new chemical stabilizers (Accredited by IRC). He explained that pilot projects should be taken with stabilized bases and sub bases and Soil stabilization technique would result in substantial reduction in consumption of expensive road construction materials. 8. Dr. Anita Das Ravindranath of Coir Board, made a presentation on the use of Coir Geo Textiles in rural roads construction. Dr. Anita Das informed that Coir in the form of geotextiles is advantageous for strengthening of weak soils, since it reduces the settlement of soil subgrade and the application of coir geotextiles is easier in comparison with existing methods of stabilization which have practical difficulties in the field. 9. A presentation on the use of Marginal Materials and Fly Ash in Road works, was made by Shri U.K.Guruvittal of CRRI. He suggested that use of marginal materials 3
in rural roads construction for low volume roads will result in saving of costly traditional materials and will also result in reduced construction time. 10. Dr. P.K. Jain, from CRRI made a presentation on Plastic Waste Modified Bituminous Surfacing for Rural Roads. He informed that the Waste plastic can be directly added to bituminous mixture and it improves properties and performance of bituminous roads. He added that Plastic waste modified mixes can be used for construction of rural roads using open graded premix carpet /mix seal surfacing, with the advantage of easy disposal of waste plastic. 11. Dr. I.R.Mithanthaya, NMAMAIT, Nitte made a presentation on Laboratory Studies on Bio-Enzyme Stabilized Lateritic Soil as a Highway Material. He informed that use of Bio-enzyme results in increased CBR value and UCS value. 12. Officials of MPRRDA made a presentation on case study of Roller Compacted Concrete Pavement (RCCP). The key benefits of RCCP detailed out in their presentation are: a. The work of R.C.C.P. done is economical in comparison to normal concrete. b. The final strength of concrete in R.C.C.P. is on the higher side in comparison to traditional concrete work. (In use of nominal mix of M-20, the strength of design mix M-40 was achieved). c. Speedily/Economical construction of R.C.C.P. due to not required expansion joints. d. R.C.C.P. becomes less cumbersome in operation and less time consuming as well. 13. Dr. Ashok Kumar from World Bank made a presentation on Some suggestions for Cost-effectiveness through innovative approaches and new technologies.

Secretary, Rural Development suggested that use of Locally available materials should be promoted in Low-Volume Rural Roads. He also opined that the possibility of using Cold Mix Technology in surface dressing should be explored. He further suggested that the use of different soil stabilization techniques should be promoted on pilot basis for low volume roads using unsealed stabilized bases. 20. It was underscored during the workshop the inspite of all support and directives from NRRDA only few pilot projects using new materials/ technologies, waste materials are being proposed by the States. It emerged that the apprehension among the engineers regarding fixing the responsibility, in case of any unexpected failures, may be one of the reasons. It was informed by NRRDA that it has been clarified at various fora and it was decided to record that in case of pilot projects 5
none of the officers will be punished in case of failure on account of nonperformance of any such new materials for which specifications are not available. At present NRRDA has guidelines for pilot projects which are placed at ANNEXURE-III. 21. Hon ble Minister, Rural Development summarized the proceedings of the workshop with following recommendations: (i) A Technical Committee should be constituted for formulating the detailed guidelines for taking up Technology Demonstration Projects / pilot projects under Research & Development. The committee should prepare an Operations Manual for taking up Research & Development projects within a period of One Month. The Research & Development Guidelines should primarily focus on : a.
