Liquid BITUMEN VG-10 VG-30 VG-40 Paving Bitumen (Straight Grade)- shall be prepared by the distillation of suitable crude, petroleum oil without subsequent blending with other grades. The material shall be homogenous and shall not foam when heated to 175°C. No mineral matter other than naturally contained in the material shall be present.
The technology for the emulsion chemistry and type of application equipment make it the most logical class of emulsion to use, especially in case of tropical countries and countries with extreme climatic conditions.
The application advantages of Cationic Bitumen Emulsion depend on coalescence of the Bitumen droplets when they contact aggregate or road surfaces. Such coalescence is called breaking. Emulsions are broadly classified according to the speed with which they break when contacted with aggregate.
Paving Bitumen specification covers physical and chemical requirement for use in Roads, Airfields and allied construction. Also some of the grades may be used for Industrial purpose.
Construction and maintenance of Roadways, Saturant for roofing felt, electrical cables for manufacturing Bitumen Emulsions, etc.
