Hot Tire Pickup Test – Dura-Rubber Performance Evaluation

Can Dura-Rubber withstand hot tire pickup?

Concrete sealers used on driveways and garage floors must endure the pressure and heat from vehicle tires, especially after driving. This test evaluates the sealer’s resistance to lifting, imprinting, or marking caused by hot tires.

The tire tracking is simulated by clamping a heated, wet tire section onto the sealed surface. After exposure, the surface is evaluated for tread imprint, coating adhesion, and any black marks left behind.

Apparatus Used:

    1.    Paint brush

    2.    Cheesecloth

    3.    “C” clamps

    4.    Aluminum panels

    5.    Tire sections (6” x 10”) – must have visible tread (lightly worn acceptable)

    6.    Concrete plaques (12” x 12” x 2”) – 28-day cured

    7.    140°F water

Procedure:

    1.    Apply two coats of Dura-Rubber to concrete plaques using a brush at a spreading rate of 100 sq. ft/gal.

    2.    Allow coating to dry for 7 days.

    3.    Soak the sealed surface with moist cheesecloth for 1 hour. (Remove cheesecloth just before clamping tire.)

    4.    Heat the tire section under 140°F running water for 1 hour.

    5.    Clamp the hot tire section to the sealed surface using “C” clamps and an aluminum panel for uniform pressure.

Test Methods:

    •    Method A: Leave clamped for 24 hours at room temperature.

    •    Method B: Leave clamped in 140°F oven for 1 hour (severe conditions).

Evaluation Criteria:

After removal of the tire, assess the surface for:

Note: Any tread marks observed were easily cleaned with mild detergent.

Report Sample Format:

    •    Type of Test: Method B

Test Results:

    •    Tread Imprint: 10/10

    •    Sealer Adhesion: 10/10

    •    Black Marking: 5/10
