Longitudinal joint performance from the bottom up.
J-Band 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.
A solution more than a decade in the making.
Longitudinal joint cracking has long been a problem for not just engineers and applicators, but the communities they live in. Thanks to collaboration between state transportation agencies, industry experts at Asphalt Materials, Inc., and the leading-edge laboratories at Heritage Research Group, it’s easier than ever to preserve your investment.
The Winning Formula
J-Band isn’t just any pavement product. This first-of-its-kind technology is the result of 15 years of developing and testing.
