The Importance of Utilizing a Certified Lab for Materials Testing

In our industry, not all materials testing labs have specific accreditations. That’s why, when choosing a partner for your pavement engineering and testing needs, it’s important to do your research. Those with certain certifications will most likely be more invested in the quality of your materials – with more reliable test data and technical competence – thus ensuring the longevity of your project. 

We discuss two important certifications to keep an eye out for when selecting the right team for materials testing services in California:

AASHTO Resource 

The AASHTO Accreditation Program (AAP) formally recognizes the competency of thousands of testing laboratories to perform specific tests on construction materials. In addition to being the largest accrediting body in the construction materials industry, the AAP is also the most widely accepted. With the global COVID-19 pandemic impacting all operations, G3 recently partnered with AASHTO Resource to successfully complete a fully virtual remote laboratory assessment.

The U.S. Army Corps of Engineers validates laboratories to perform testing related to concrete, souls, asphalts, and aggregates. The USACE MTC, or Materials Testing Center, is the only agency authorized to validate commercial laboratories to work for the Corps of Engineers. There are specific requirements through the MTC that must be met and confirmed before validation is granted. This authorizes the laboratory to perform testing on US Army Corps of Engineers projects.
