DETERMINATION OF VISCOSITY CUT-BACK BITUMENS
IP 72 - NFT 66005 - DIN 1995
These standards cover the determination of viscosity cut-back bitumens, expressed in convectional units, by means of a standardized apparatus. They do not apply to cut-back bitumens containing polymers.
This test method provides a measure of the viscosity by determining the time of efflux of 50 ml of a cut-back bitumen, at 40�C, through a 10mm orifice
