Asphalt Materials, Inc., a Heritage Group Company, formed in 1956, has been continually focused on the asphalt business. The core strength of our business is the formulation, manufacturing, and R&D of asphalt binders and emulsions. We supply high quality products and services allowing us to excel in pavement preservation techniques and construction services to assist federal, state, & local authorities in building economical and reliable pavements. We work closely with the Heritage Research Group to utilize the latest technologies to ensure the highest quality asphalt products and processes are produced and applied. This collaboration led to the development of our J-Band® product which sets the standard as a Void Reducing Asphalt Membrane (VRAM) or Longitudinal Joint Sealant (LJS). But unlike other treatments, it significantly reduces air voids in longitudinal joints from the bottom up – literally. This not only extends the life of the joint but improves the performance of the entire pavement.

  • J-Band
    First used on projects in 2002, J-Band tackles the toughest problem in asphalt paving: longitudinal joint failure. J-Band fills air voids in the joint, making it more impermeable to the destructive forces of air and water.

  • J-Band is applied before the surface course is paved, underneath where the longitudinal joint will eventually be. After paving, the heat of the HMA causes J-Band to migrate up into the overlay, filling air voids as it goes. This drastically decreases permeability, protecting the joint from air and water. J-Band can increase the life of your road from 4 to 5 years to 15+, saving you from the cost and stress of maintenance. Learn more about how J-Band works by watching this short video:
