It is waterproof and flammable, and this exceptional natural substance has been used by people for all kinds of duties and instruments for a minimum of the past 40,000 years.
The bitumen is positioned in to a normal tar viscometer or efflux viscometer and its temperature is raised to test temperature specified (35, 40, 45, fifty five& 600C). When the temperature reaches respective take a look at temperature orifice valve is open time elapse is noted to gather the bitumen of 50ml. The time required to collect a bottom container of 50ml is five not directly the viscosity of bitumen.

These rocks are crushed and heated and consolidates by sudden cooling. Laboratory research have proven chemical extracts of asphalt fumes to have most cancers-inflicting and mutagenic properties. For example bitumen 40 50, painting of asphalt extracts on mouse pores and skin produces tumors that improve with dose .
