In October 1973, the Highway Research Board (HRB) was set up under the auspices of the IRC to give undivided attention to research and development activities.  Identification Monitoring and Research Application (IMRA) Committee looks after the Research work and compiles data of road research work done in the country on yearly basis. Under the aegis of HRB, an Expert Committee for "Accreditation of New Materials and Techniques" was constituted for the purpose of recommending usage of New Materials /Products / Technologies on trial basis for road and bridge works in India. The list of accredited materials by IRC from 2017 to 2025 is available at the IRC website. For wider dissemination, the HRB publishes State-of-the-Art Reports, Highway Research Record and Highway Research Journal.
