J-Band Longitudinal Joint Sealant
Elevate your
Pavement
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.
Efficient Application
Even though it’s a new way of doing things, J-Band is applied immediately prior to paving, as part of the normal HMA construction process.
Upward Moving
Unlike other joint treatments, J-Band migrates upward, filling voids and fending off the joint’s enemies: air and water.
Wide Coverage
Using an inline parallel spray bar, J-Band covers an area 12 or 18 inches wide on top of existing pavement under the eventual location of the longitudinal joint.
Long Lasting
J-Band is proven to extend the life of your pavement’s longitudinal joint threefold, from the usual 4-5 years without J-Band — to 15+ years with J-Band.
Fast Acting
In no more than 30 minutes after applying J-Band, the road is ready for construction traffic, keeping the installation process efficient and traffic flowing.
Money Saving
J-Band is a long-term proposition. On the average roadway, every $1 invested in J-Band typically saves agencies $2 in avoided and deferred maintenance costs.
Proven Performance
J-Band has been successfully installed with proven results on roads throughout Illinois as well as Ohio, Indiana, Michigan, Iowa, and Missouri. Using J-Band helps save what matters most: time, money, and lives.
