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.
