New Road Construction Guidelines
Context
Indian roads and highways often suffer from cracks and sticky surfaces during the summer heat. To address these issues and make highways smoother and safer, the Ministry of Road Transport and Highways (MoRTH) has introduced new guidelines for road construction.
Key-highlights of the Guidelines
- Temperature and Traffic-Based Materials: The surfacing material for all new road projects will be chosen based on temperature variations and axle load (traffic weight).
- Bituminous Binders: Different grades of bituminous binders will be specified based on factors such as ambient temperature, rainfall, snowfall, and speed. These binders are crucial in creating a durable and flexible road surface.
- Climate Considerations: It includes specific mixes for different climatic zones across India to ensure that the road materials used are appropriate for the local environmental conditions.
- Application: These guidelines will apply to all new road projects. Additionally, the quality of highways will be checked during the re-laying of existing roads.
