Aggregate Testing Services

Laboratory testing of aggregates takes place in our purpose-built, air-conditioned and temperature controlled laboratories.

As a major supplier to the UK construction and quarry products markets, aggregate testing is one of the core services available from CTS.

In addition to our standard suite of aggregate tests, our specialist department contains a large shear box apparatus (300mm square), capable of determining the Effective Angle of Friction parameters of soils and aggregates by direct shear to methods described in BS 1377 and The Specification for Highway Works (600 Series, clause 636), both methods being UKAS accredited.

In 2016, we gained further accreditation for the determination of friction and adhesion in accordance with SHW 600 Series, clause 639; allowing for the testing and analysis of Geotextile/Soil interface.
