What are the benefits of having an AASHTO Accreditation?

The process of becoming accredited helps the laboratory improve its quality through AMRL’s rigorous review of testing, equipment, and quality system management. Many laboratories that are new to the program find the process to be a bit overwhelming but ultimately they appreciate the benefits of knowing that they’re laboratory is maintaining the highest standard in the industry.

Once a laboratory obtains the accreditation, they become part of the elite group of materials testing laboratories that can start bidding on projects that require the accreditation. Specifying agencies include the DOTs, FHWA, the FAA, and many local, state, and regional authorities.

Being accredited also as a laboratory into the AMRL community of accredited laboratories, the people that work for laboratories in our program do more than just conform to standards – they set the standards. Many of the participants in our programs write and submit balloted changes to ASTM standards. As an AASHTO program, AMRL is able to offer its accredited labs the ability to submit a change to an AASHTO standard too – even if you don’t work at a state DoT, your voice can be heard by the AASHTO Subcommittee on Materials.
