State of the art bitumen sampling and testing

Intertek Caleb Brett

Bitumen can suffer deterioration while stored in tanks or loaded into trucks, therefore it is vital companies ensure the quality of their bitumen remains stable and the specification of the product remains unchanged.

Intertek can offer state of the art independent bitumen inspection and testing facilities to clients across Europe. The Intertek Bitumen laboratory in the UK is managed in accordance with ISO 9001, 17025, 14401, OSHAS 18001 certifications and can provide services covering bitumen, and polymer modified bitumen and emulsion inspection and testing.

The capabilities cover the testing of bitumen to BS EN 58, BS EN 13924-2, BS EN 12591 and BS EN 13808 specifications. This fully covers the testing requirements for standard bitumen.

Intertek’s bitumen testing capabilities are complemented by bitumen inspection capabilities.
