Elevate your
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.

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 4-5 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

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.
