Addition of facility in Road Asset Management Group of CRRI for conducting Dynamic Modulus, Flow Number and Flow Time Tests (NCHRP Project 9-29)


  • Dynamic Modulus – Absolute value of Complex Modulus (dividing peak to peak stress by peak to peak strain subjected to sinusoidal loading)
  • Flow Number – Number of repeated load cycles (repeated compressive stress pulses) corresponding to the minimum accumulation rate of change of permanent axial strain

                        - Related to rutting resistance of HMA

Dr.S.Velmurugan was bestowed with the Outstanding Scientist Medal by the Construction Industry Development Council (CIDC) in March, 2015 during the 7th Viswakarma Award Function

Vishwakarma Award is instituted by CIDC (An organisation started by the erstwhile Planning Commission, Government of India and the Construction fraternity) aimed at motivating individuals and organizations to raise their performance in their specific domain leading to significant contribution for the growth and development of the Indian Construction Industry. - The first ever person in CSIR - CRRI to acquire such a distinction.

New Process Technology Developed for Harder Grade Bitumen VG-40

IS:73-2013 specified four grades of bitumen such as VG-10, VG-20, VG-30 and VG-40. Indian refineries are producing only two grades of paving bitumen such as VG-10 and VG-30, which are not adequate for entire prevailing climate and traffic conditions of India. IRC:111-2009 recommend VG-40 bitumen, if commercial vehicles exceed 2000 per lane per day.  Recently Indian Road Congress Standard (IRC:37-2002) focus for use of harder grade bitumen for high modulus mixes and better performance.
