Lincs Laboratory

Laboratory and site testing

We undertake a comprehensive range of tests on a variety of construction materials. We can determine suitability for use and consistency of quality.

Aggregates and concrete

Current tests available are as follows:

  • physical tests and mechanical tests - particle size, density and shape characteristics, rost heave, strength and compaction characteristics
  • chemical tests - sulphate and chloride content, chemical compounds in salt for winter maintenance
  • concrete tests - compressive strength and density of hardened concrete cubes.  Concrete cubes should be accompanied with a completed 150mm concrete cubes form or a 100mm concrete cubes form.

Bituminous material testing

Current tests available are as follows:

  • compliance testing, which includes
    • binder content
    • grading and the maximum density of bituminous mixtures
    • density and air void content of cores
    • penetration and softening point of binders
    • water and binder content
    • efflux of emulsions used in highway pavement construction
  • investigation testing – Logging and Tar Content of bituminous cores removed from the pavement

Soil testing

Current tests available are as follows:

  • classification tests - plasticity, moisture content, particle size, and density
  • physical testing - California bearing ratio (CBR), dry density moisture content relationship, compaction, and consolidation

Site testing services

Current tests available are as follows:

  • compliance - surface texture and regularity, the reflectivity of white lines, compaction of aggregates and bituminous materials
  • investigation - coring, pavement stiffness, bearing capacity
  • performance - bituminous materials, concrete, and granular materials

You can deliver samples directly to the laboratory between 8 am and 5 pm, Monday to Friday. We can also collect samples direct from your site.
