Bitumen is the oldest known engineering material and has been used from the earliest times as an adhesive, sealant and waterproofing agent. As long ago as 6000BC the thriving ship- building industry in SUMERIA used naturally occurring bitumen, found in surface seepage in the area in the Indus Valley, now in Pakistan, there is a particularly well-preserved water tank, which dates back to around 3, 000 BC. The stone blocks in the tank's walls are bonded with natural bitumen and there is a vertical bituminous core in the centre of the wall this same principle is used today in modern dam design.
Bitumen's versatility as a construction material is unparalleled. Having been used as an adhesive, sealant and waterproofing agent for over 8, 000 years, its uses now include: the construction and maintenance of roads, airfields and all areas where asphalt is used; roofing; damp proofing; dam, reservoir and pool linings; soundproofing, pipe coatings, paints, and many other applications.
Processing of bitumen yields other grades of bitumen products and their applications are: Oxidized Bitumen - produced by more vigorous air blowing; they are more 'rubber like' and less temperature susceptible than the paving grades. Used in roofing, waterproofing, electrical products, and many others.
The most popular grades are; grades 95/25, 85/25, 90/40, and 115/15. We are also capable of producing other grades of Blown Bitumen upon request by our customers. Oxidized Bitumen high softening temperatures qualify them as excellent sealant for prevention from bleeding in high temperature applications. Blown grade bitumen shall be broken up into small pieces (for blown grade in molded cake form) and heated slowly to the application temperature of 220° C to 230° C.
