IIT-H Research Develop Models Promoting For Long-Lasting Roads
The Indian Institute of Technology (IIT) Hyderabad
has successfully developed the models to reduce the number of road accidents in the country. The models are prepared so as to predict road surfaces and its pavement’s performance.
Considering the nation, India holds the second largest road network after the United States, the research now offers with a solution which and accurately predict the pavement performance and helps for a construction based field for the long-lasting roads across the nation.
Reliability-Based Design Optimization - RBDO - is a modeling technique that combines the
optimization approach with the reliability assessment of the structures.
B Munwar Basha, associate professor department of the civil engineering, IIT Hyderabad and PRT Pranav, the research scholar, with a team of researches, used the RBDO to predict the safety of the multi-layered flexible pavement structures against the fatigue and the rutting criteria. This prediction is also based on the simultaneously to considering the variability arising from the individual design parameters.
The flexible pavement included four layers, subgrade, granular, subbase, base and of the bituminous layers where the bituminous layer’s thickness and the resilient modulus of the base layer being the most of the important and the influential parameters for fatigue failure. The pavements included the complex layered structures which are being influenced by many of the factors such as material properties, the environment, and the climatic conditions, the traffic volume, subgrade soil profile, construction practices, and pavement the aging process.
Researchers claim that in modern pavement construction and accurate prediction of pavement performance will help develop robust design procedures.
Hence the transportation agencies need to go for he innovative techniques to address the relevant variabilities which are associated with the influencing factors, which was shared by Prof. Sireesh Saride, department of civil engineering, IIT Hyderabad.
Indian Institutes are stepping closer and growing with faces of innovation.
