Bituminous Testing

Bituminous road surfacing materials are produced by mixing mineral aggregate with a bitumen binder in predetermined quantities and within defined temperature ranges. Other materials are sometimes added to the mixture, including fibres, polymers and pigments to produce specific performance characteristics.

At ACS Testing we are UKAS accredited to carry out a wide range of testing covering British (BS) and European (EN) standards on Bituminous materials both on site and in the laboratory. ACS Testing provide highly skilled technicians who all hold current CSCS cards and are comprehensively trained in the safety aspects of the work they carry out in accordance with appropriate method statements and risk assessments.


Our Bituminous Laboratory covers a comprehensive range of testing, included but not limited to;
