Aggregate Materials TestingAggregate Materials Testing


A full range of aggregate testing at every stage. EXL tests the physical properties of the aggregate, such as gradation, fracture, and durability. These tests help ensure the integrity of concrete structures and asphalt road construction projects. EXL materials testing labs are equipped to provide you broad aggregate testing at every phase of your project. We also have the ability to mobilize directly to your project sites to perform on-site testing. We’ll test aggregate according to different testing protocols as required, including your Provincial Transportation Authority Test Procedures, as well as, CSA, ASTM and AASHTO. From our on-site quality control monitoring when you source the aggregate, right through to physical characterization in our specialized laboratories, our services include testing for:

  • Petrographic examination
  • Sieve analysis
  • Density and water absorption 
  • Cleanliness or the material finer than 75 um
  • Particle shape and percent of fracture
  • Fine particle size distribution 
  • Soundness
  • Resistance to abrasion by Micro-Deval
  • Organic impurities
  • Oversize particle size distribution and shape
