Test for Bitumen Emulsion: Viscosity by Saybolt Furol Viscometer Purpose Viscosity indicates the resistance to flow due to its internal friction. Higher the viscosity, lower the rate of flow. The test is conducted to see if it is in the specified range. The Test result is expressed in seconds for the flow of 60 cc … Read more
Aging of Bitumen Binders Bitumen, like any organic matter, is affected by factors like presence of oxygen, ultraviolet rays and changes in temperature. These factors are responsible for hardening of bitumen. Hardening results in Decrease in penetration value Increase in softening point temperature and Increase in penetration index (PI). For increased life of bituminous pavement … Read more
