• J-Band

    Associated Asphalt product "J-Band" applied to the center of a road with cars driving by.

Elevate your pavement performance from the bottom-up.

There’s a new way to extend the life of longitudinal joints: J-Band®, the bottom-up joint solution.

Your pavement project is a major investment, no matter the application. That’s why Associated Asphalt supplies only the highest quality asphalt mixtures. J-Band® is the longitudinal joint deterioration solution you’ve been looking for to strengthen your centerline.

The Winning Formula

J-Band® was formulated as a VRAM (Void Reducing Asphalt Membrane) to significantly reduce air voids in longitudinal joints from the bottom up. Applied under the longitudinal joint in new asphalt, the J-Band® migrates upward as hot mix is installed on the top layer to fill voids and block water and air from creating pockets that will later deteriorate the asphalt.

PennDOT’s program led to the introduction of a VRAM Standard Special Provision that can be used on projects let on or after April 14, 2023.
