Qualified Products List
Overview
Effective Date: June 2005
This Specification governs the Qualified Products List (QPL) for materials used by The Montana Department of Transportation (MDT),
and describes probation and qualification procedures, quality monitoring requirements, disqualification, and sampling and testing.
Qualified Products List
The Materials Bureau maintains the QPL. MDT confirms materials appearing on the QPL meet the Montana specifications applicable to each product on the list. Some materials may be accepted through the QPL or by project specific testing. Certain materials are required by contract to be approved and listed on the QPL in order to be used on MDT projects. Refer to the contract documents to determine the method of acceptance for each product.
Quality Control Testing
Producers must have an acceptable quality control (QC) plan and perform adequate QC testing to ensure consistent product quality. Products produced with inadequate quality control will not be accepted for inclusion on MDT’s Qualified Products List.
Initial Qualifications and Probationary Products
Products meeting the initial qualifications as described will be accepted on a probationary basis for one year.
This product will be designated with a P on the QPL list which signifies that it is on probationary status.
Those products will be tested at the normal rate and frequency. If the product has satisfactorily met Montana
specifications for one year it will be placed as a fully approved product on the QPL which will be designated with a Q.
If a fully approved product on the QPL list fails to meet Montana’s specifications it may be placed on probation. If
a product on probation continues to fail it may be taken off the list as described in the disqualification section.
National Transportation Product Evaluation Program (NTPEP) Listings
Products tested by NTPEP may be added to the Qualified Products List without additional testing when NTPEP testing demonstrates the product meets MDT specifications. Submit a Request Form with a quality control plan and NTPEP test results to add a NTPEP product to the QPL. Products removed from NTPEP’s list will also be removed from MDT’s QPL. Reapplication will be required for reinstatement.
Random Testing and Auditing
The MDT reserves the right to sample materials on the QPL for testing and to perform audits of test reports.
MDT representatives may sample material from the manufacturing plant, the project site, and other locations.
MDT reserves the right to test samples to verify compliance with
Standard Specifications for Road and Bridge Construction and corresponding supplement specifications.
Producers must maintain a complete record of all test reports for the previous two years and current calendar year.
Disqualification
Products that do not perform or are found to be non-compliant with MDT specifications may be removed from the QPL at any time and remain unlisted until such time that adherence to the specifications can be verified and the product has undergone satisfactory performance evaluation.
