TIKI BITUMEN

Description

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 materialshall be present

Recommended use

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.
