VRAM Preserves the Longitudinal Joint for over 20 Years on US-51  

J-Band
Longitudinal joints are one of the first parts of a pavement to fail. As a road’s most permeable location, air and water seep into voids at the construction joint, leading to premature cracking, potholing and delamination of the surface.   However, there is a materials-based approach to protecting longitudinal joints....

J-Band’s Shadow on Road Construction

J-Band Shadow appears on a freshly paved HMA mat
The Shadow Take a close look at a hot mix asphalt (HMA) mat paved over J-Band. In the right circumstances, there is a shadow that appears. Above the band where the J-Band was laid, the HMA mix often appears visibly darker after the rolling operation. Why does this happen and...

Illinois State Route 33 is Preserved with VRAM Application

VRAM, a thick band of asphalt, is being shot from a truck on the centerline of a road
Across the state of Illinois, specifications encourage the increased use of Void Reducing Asphalt Membrane (VRAM), commonly known as a Longitudinal Joint Sealant (LJS) in Illinois, to prohibit longitudinal joint deterioration. J-Band®, Asphalt Material, Inc. (AMI)’s premier VRAM, works by filling air voids within the longitudinal joint from the bottom...

The Need for a Longitudinal Joint Sealant  Every road is built with significant weak points where water can more easily permeate the pavement causing cracks and potholes. Road experts agree that longitudinal joints and rumble strips are the first to succumb to deterioration. Longitudinal joints typically have higher than normal...

Road construction can be dangerous. Vehicles zoom past field workers at hazardous speeds. One of the riskiest places to be is near the centerline of a busy road. Quality control technicians have lost their lives when performing density tests at the joint. Unfortunately, density testing of the center longitudinal joint...
