Materials Testing Laboratory

Materials Testing Laboratory

Cambium maintains and operates its own materials testing laboratory facility which complements our geotechnical and field inspection consulting services. We provide a complete service line in geotechnical engineering from the initial geotechnical investigation through to on-site construction inspections, including laboratory construction material testing on the various products employed at the project site. Our experienced senior laboratory staff oversees a team of competent, certified technicians trained in the various materials testing methods. The laboratory is Canadian Council of Independent Laboratories (CCIL) certified in the following areas:

CCIL Aggregate Laboratory Certification:

  • Aggregate Quality Control Laboratory (Type C)
  • Aggregate Physical Property Laboratory (Type D)
  • Superpave Aggregate Consensus Properties

CCIL Asphalt Laboratory Certification:

  • Asphalt Mix Compliance – Marshall & Superpave Methods (Type B)
  • Solvent Extraction
  • Asphalt Mix Design – Marshall Method (Type A)

CCIL Concrete Certification:

  • Category 1 Intermediate Certification

Additional Tests:

  • Soundness of Fine and Coarse Aggregates by Use of Magnesium Sulphate
  • Resistance of Fine Aggregates to Degradation by Abrasion in the Micro-Deval Apparatus
  • Resistance of Unconfined Coarse Aggregate to Freezing and Thawing
  • Resistance of Coarse Aggregates to Degradation by Abrasion in the Micro-Deval Apparatus
