What Is Asphalt and Bituminous Testing?

Asphalt and bituminous tests evaluate the quality, durability, and compliance of materials used in a wide range of road, car park, and infrastructure projects. By providing insights into the characteristics of road construction materials, these tests play a vital role in ensuring structural integrity, preventing premature deterioration, and reducing maintenance costs.

There are many types of bituminous and asphalt test methods, assessing properties such as viscosity, penetration, softening point, ductility, and density. Results from these tests are essential for ensuring selected materials meet the required specifications for safety, longevity, and cost-effectiveness.

Our Asphalt and Bituminous Test Services

Ensuring the quality of bituminous mixtures in road construction is critical to achieving compliance with contract specifications. The use of long-lasting and durable materials from the start also minimises setbacks during construction and informs cost-effective maintenance strategies for the future.

At CTS, we offer a comprehensive range of UKAS-accredited* on-site and laboratory-based bituminous and asphalt testing services across the UK. Our expertise verifies that materials meet industry regulations and specifications, providing assurance of quality, durability, and long-term performance.
