The laboratory, not the company, performing the testing must be accredited by the AASHTO Materials Reference Laboratory (AMRL) or a comparable laboratory accreditation program approved by MnDOT and the FHWA for all test procedures performed. To be a part of MnDOT’s prequalification list, firms do not have to be accredited laboratories in all of fields. Use the website to verify what laboratories are accredited in which fields, as the prequalification list is for general approval.
