    Qualified Materials

    Qualified Materials



    Only qualified materials that have been approved according to Section 106 of NJDOT Standard Specifications may be used for construction or maintenance of New Jersey's transportation infrastructure. NJDOT maintains databases of qualified materials for materials that are required to be on a qualified products list (QPL) for use. If a material is required or permitted to be on a QPL, the QPL is referenced in the materials specification in the 2007 NJDOT Standard Specifications.

    NOTE: Not all materials specified by NJDOT are required to be from a QPL. For those materials that are not required to be on a QPL for use on construction projects, the material is approved according to the Materials Questionnaire process as detailed in Section 106 of NJDOT Standard Specifications.


    Qualified Materials Databases
    There are databases for the following materials/products:


    1. Standard Materials Qualified Products List
    The Standard Materials QPL is for materials other than aggregates, electrical materials, or intelligent transportation systems that are required in Section 900 of the NJDOT Standard Specifications to be on a QPL prior to use by the Contractor. Following is a list of the materials on the Standard Materials QPL:



    • Cement Suppliers
    • Concrete Admixtures
    • Epoxies
    • Fiberglass Composite Materials
    • Guide Rail End Treatments and Spacers
    • Inertial Barrier Systems
    • Joint Adhesives
    • Joint Sealers
    • MSE Wall Systems
    • Prefabricated Modular Wall Systems
    • Structural Steel Paint Systems
    • Quick Setting Patch Materials
    • Rebar Coupling Devices
    • Reflective Sheeting

    2. Aggregates Qualified Products List
    DOT maintains a separate Aggregate Producers database containing producers and corresponding sizes of aggregate materials that are qualified to supply DOT projects. This database is a compilation of geologic evaluations and quality tests performed on various aggregate sources that may supply aggregates to DOT. The data reflects average test values of the latest results. It does not reflect the legal qualification of the producer to supply materials to DOT sponsored projects. Supplemental Specifications for an individual project and other contract documents should be reviewed to determine if a producer is legally qualified to supply material to a project. Data changes are noted in the remarks column. Terminology can be found on a glossary page. This database was correct when developed, however, producer's materials are subject to change and all aggregate sizes are subject to field approval at the time of use.


    3. Concrete and Asphalt Plants Qualified Products List
    DOT maintains a separate Qualified Plants database contains qualified producers of asphalt and concrete. The database contains producer names and locations that are qualified to supply DOT projects.


    4. Electrical Materials and Intelligent Transportation Systems Qualified Products List
    NJDOT Standard Specifications discusses qualified electrical materials. DOT maintains databases for qualified electrical materials, and qualified intelligent transportation systems.


    Materials Approval Procedures (MAP)
    Materials Approval Procedures (MAP) have been developed for materials that are required to be on the QPL prior to use. A standardized MAP was adopted for each type of material as the approval process is specific for each type of material.

    MAP 101: Aggregates
    MAP 102: HMA Plant
    MAP 103: Concrete Plant
    MAP 104: Cement
    MAP 105: Air Admixture
    MAP 106: Chemical Admixture
    MAP 107: Flyash
    MAP 108: Slag
    MAP 109: Silica Fume
    MAP 110: VMA
    MAP 111: Corrosion
    MAP 112: Quick-Setting Patch Material
    MAP 113: Non-shrink Grout
    MAP 114: Epoxies
    MAP 115: Prefabricated Modular Walls
    MAP 116: MSE Walls
    MAP 117: Rebar Coupler
    MAP 118: Sign Sheeting
    MAP 119: Paint (IEU & OEU)
    MAP 120: Paint
    MAP 121: Guard Rail End Treatment
    MAP 122: Guard Rail Blockout
    MAP 123: Hot Joint Sealant
    MAP 124: Cold Joint Sealant
    MAP 125: Poly Joint Adhesive
    MAP 126: FRPL
    MAP 127: FRPP
    MAP 128: FCCP
    MAP 129: Inertial Barrier
