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.

Longitudinal Joint Sealant
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


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.

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.

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.

Unlike other joint treatments, J-Band® migrates upward, filling voids and fending off the joint’s enemies: air and water.

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®.

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.
