Grain size distributions of sand, foundation material and asphalt granulate

The correct grain size distribution of foundation materials is essential for the durability and performance of roads. Heavily trafficked roads require a different foundation structure than lightly trafficked ones. By varying the material type, grading, and any additives, the foundation can be made more flexible or stiffer. This directly affects the material's permeability and workability.

A professional grain size analysis helps prevent issues during both the construction phase and the use phase. We assess whether sand, foundation materials, and recycled substances such as reclaimed asphalt (RAP) meet the required technical and environmental standards.

Benefits of a particle size distribution analysis.

  • Avoid delays or rejections by assessing material suitability in advance

  • Get confirmation that the supplied sand/foundation meets the requirements specified in the specifications.

  • Gain insight into key properties such as permeability, stability, and workability

  • Ensure the reliable use of recycled materials like reclaimed asphalt

  • Comply with specifications, standards, and environmental regulations

Compaction testing of sand beds and foundation layers

We perform precise measurements to check whether the applied sand or foundation material has been compacted adequately according to the RAW specifications and CROW guidelines. This prevents future subsidence and provides a stable base for roads or constructions.

In-situ Density Testing

In-situ density testing is used to assess the compaction of sand layers and foundation materials directly on-site. These tests provide insight into the quality of the executed work. Depending on the project requirements, either the sand cone method or the nuclear method is used.

Asphalt delivery inspections

Ensure your asphalt construction meets all contractual and technical requirements before handover. We assess composition, compaction, air voids and layer thickness using asphalt core samples. With our independent evaluation, you reduce the risk of costly remedial work and can proceed to delivery with confidence.
