Our laboratory has the equipment and staff knowledge, experience, and expertise to perform many standard and uncommon tests on aggregate used in the construction industry. Our staff is well versed in ASTM, AASHTO, CSA, USACE, and EN test procedures and have the flexibility to perform many tests outside our standard services when called upon. We can perform on-site sampling or perform testing on samples shipped to us. Testing includes standard physical properties, abrasion resistance, chemical attack, freeze-thaw durability, and many others.,yps porn
