Accelerated Pavement Testing

Flexible Pavements
The Indian road network is mainly built with flexible pavements, because of ease of construction and low initial cost as compared to concrete pavements. The flexible pavements are designed as per Indian Roads Congress (IRC-37) method and constructed as per Ministry of Road Transport and Highways (MoRTH) specifications. The design of flexible pavement is mainly affected by sub-grade soil, component material characteristics, design wheel load, climatic and environmental condition. The pavement is designed for a standard axle load of 8.16 t and higher loads are expressed as Equivalent Single Axle Load.
