Hyderabad: Researchers from the Civil Engineering Department of the Indian Institute of Technology (IIT) Roorkee have been awarded the prestigious IRC National Award under the category of Bihar PWD Medal for Best Paper on Road Research for their research paper titled “Effect of modulus of Subgrade Reaction on Thickness of Rigid Pavement –A Case Study” during the Indian Roads Congress 78th Annual Session held in Bengaluru.
The award was presented to Prof. G.D. Ransinchung R.N., Surender Singh (Research Scholar), Prof. Praveen Kumar and Prof. Manoranjan Parida from IIT Roorkee for their research and study on addressing the shortcomings and flaws in the existing IRC-58, the only standard code available in India for construction of cement concrete pavement.
The team studied the existing IRC-58 code in depth to analyze the various gaps in the existing system and to recommend the necessary changes and modifications to make the IRC-58 code more robust.
The team analyzed various parameters related to the compacted subgrade soil, the sub-base and the cement concrete slab, and identifies the gaps and shortcomings in the current guidelines for construction. The study and the subsequent paper was an attempt to revamp the existing standard code “IRC:58-2015, Guidelines for the Design of Plain Jointed Rigid Pavements for Highways”, the only standard code available in the country.
The team has concluded that modifications in the existing practices can help reduce the cost by around 20-25% and also be a great help for the PWD engineers, stakeholders and the rural engineering services who are looking at the implementation of the Pradhan Mantri Gramin Sadak Yojana (PMGSY).
“This is the need of the hour to revamp the present guidelines of concrete pavements. We suggested incorporation of various new parameters for revisions in the present guidelines. With these additions and changes there will be a significant improvement in terms of quality as well as reduction in the cost of project construction,” Dr. Ransinchung said.
