PATIALA: IIT Ropar and the National Highway Authority of India (NHAI) have partnered for two research projects, including the project on Slope Monitoring and Landslide Risk Quantification for Hilly Roads and the second on the use of rice husk ash, bagasse ash and clinker as backfill material for highway embankment.
Landslides are recognized as one of the major natural hazards due to their global importance. According to the National Disaster Management Authority (NDMA), around 15 percent of India’s total land area is affected by landslide risk. One of those places is the Himalayan region, where several devastating landslides have been reported in the past. Landslides pose a serious threat to infrastructure, especially hilly roads.
The present study aims to quantify the risk of landslide for a section of highway in the Himalayan region. The study area will be decided in consultation with the NHAI. In this study, a comprehensive landslide risk analysis will be performed based on geotechnical and remote sensing test data. Based on the analysis, appropriate landslide mitigation measures will also be recommended under this project. In addition, this study also proposes to set up a monitoring system composed of sensors and data loggers to assess the performance of the recommended landslide mitigation program.
The researchers of this project are Professor Naveen James, Reet Kamal Tiwari, Department of Civil Engineering, IIT Ropar and CK Narayanan, Department of Computer Science and Engineering, IIT Ropar.
Another project, “The use of rice husk ash, bagasse ash and clinker as backfill material for highway embankment”, is investigating the possibility of using agricultural and industrial wastes, such as ashes. rice husk, bagasse and clinker, as backfill material for stable backfill, in road construction. A stable backfill must be able to withstand traffic loads without excessive strain during the life of the pavement. Compacted soil is widely used for backfill construction nowadays.
Rice husk is available in abundance in rice-growing regions, particularly the Punjab, while bagasse ash is the by-product of sugar factories. Bottom ash is the by-product of the combustion of coal which is collected at the bottom of the furnaces. The performance of rice husk, bagasse and clinker ash will be analyzed, and an optimal proportion of ash mixture will be proposed. The response of these materials as backfill material, under traffic loads and seismic loads, will also be analyzed. An environmental impact study will also be carried out to study the influence of these materials on groundwater pollution and underground pollution. The project has a duration of four years and during the last year the proposed mixture will be used in the construction of a section of highway and the performance of the road will be evaluated for one year.
The investigators for this project are Resmi Sebastian (PI) and Raheena M (Co-PI), Department of Civil Engineering, IIT Ropar.
