The penetration value of residue from distillation upto 360°C of rapid curing cutbacks bitumen is -
80 to 120
However, a common and important range specified for the residue, especially for RC-3 grade, corresponds to a penetration value of 80 to 120. The range 80 to 120 aligns with the typical specifications for the penetration value of the residue from distillation up to 360°C for certain grades of rapid curing cutback bitumen.
