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.
J-Band Longitudinal Joint Sealant
Elevate Pavement Performance from the Bottom Up
J-Band sets the standard as a Void Reducing Asphalt Membrane (VRAM). Unlike other treatments, it significantly reduces air voids in longitudinal joints from the bottom up. That extends the life of the joint and improves the performance of the entire pavement.
How J-Band Works
Six Reasons Agencies Spec J-Band
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.
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.
Upward Moving
Unlike other joint treatments, J-Band migrates upward, filling voids and fending off the joint’s enemies: air and water.
Long Lasting
J-Band is proven to extend the life of your pavement’s longitudinal joint threefold, from the usual 4 to 5 years without J-Band to 15+ years with J-Band.
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
