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. Our bituminous materials testing can be performed both on site and in the laboratory. ACS Testing provide highly skilled technicians who all hold current CSCS cards. They are comprehensively health and safety trained in accordance with appropriate method statements and risk assessments.
Bituminous Test Types
Our Bituminous Testing Laboratory covers a comprehensive range of testing, included but not limited to:
|Test||Method||What it shows|
|Binder Content||BS EN 12697-1||Breaking down the constituents of blacktop to determine the mineral grading, filler content and quantity of binder.|
|Particle Size Distribution||BS EN 12697-2|
|Maximum Density||BS EN 12697-5||The maximum density of a mix used to define the 100% when comparing to in-situ density or bulk density of cores|
|Bulk Density||BS EN 12697-6||Measuring the layer density of a core sample|
|Air Voids Content||BS EN 12697-8||Calculating the difference between bulk density / maximum density to provide air voids.|
|Percentage Refusal Density (PRD)||BS EN 12697-9||Measuring density of core layer, heating, compacting and re-measuring density.|

The ACS Geo-Environmental Consultancy Department has been operating as part of ACS for over 10 years.
ACS offers a comprehensive range of professional on-site testing, all carried out by our fully trained site technicians.
From our main laboratory in Poole, Dorset, ACS provide quality testing and material consultancy for the construction and civil engineering industry.
ACS carries out testing on new bituminous binder material and testing on hardened material for physical and chemical properties. Circa pre 1980’s Tar (Carcinogenic effects) was also used as a binder, ACS staff can sample and test materials to assess if Tar was used.
Concrete was the first service to be offered by ACS back in 1987. Since then, we have increased our scope to cover a wide range of UKAS Accredited testing methods on fresh and hardened concrete.
ACS can sample and test new and hardened mortar. Hardened mortar for mix proportions and constituents, new mortar for compressive and flexural strength.
At ACS we offer an efficient and reliable chemical analysis service for waste soils and construction materials using various test solids and leaching procedures specified by the Environment Agency.
The ACS chemical laboratory was established in 2007. It complements the physical materials testing service provided by ACS by offering a range of chemical analytical services.
Our purpose-built analytical laboratory enables ACS to provide a comprehensive sampling, monitoring and analysis service on a wide range of leachate and water samples.
Our newly refurbished stone testing laboratory has given us the opportunity to expand our testing scope. In addition, we have increased production and improved on our turnaround of samples.
