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®

J-Band®, The Bottom-Up Joint Solution
Efficient Application, J-Band® application

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, J-Band® application

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, J-Band® application

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, J-Band® application

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® application

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® application

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.
