Protecting more than the middle of the road.
Rumble strips play a critical role in keeping drivers safe. However, they are typically milled over a longitudinal joint, the part of the pavement that is already most vulnerable to water infiltration and early deterioration. To reinforce rumble strips, their pavement foundation—the longitudinal joint area—needs to be strong. That's a job for J-Band.
Saving Lives and the Life of Your Road.
By applying J-Band under centerline and shoulder rumble strips, you can protect longitudinal joints, the pavement structure, and the lives of workers and drivers alike. Long-lasting rumble strips make for safer roads.
Centerline rumble strips can reduce left of center crashes by distracted drivers on two lane roads by more than 40 percent
Water collects at the centerline – the most permeable part of the pavement and where rumble strips are installed to improve safety.
Apply J-Band at the time of construction to reduce permeability under the surface where centerline rumble strips will be installed.
J-Band works from the bottom-up. Migrating upward, filling voids around the rumble strip, reducing permeability.
J-Band results in less frequent maintenance which means less worker exposure to dangerous work zones.
Every dollar invested in J-Band can save at least two dollars in avoided and deferred maintenance costs.

"Longitudinal joint performance is improved with the use of void reducing asphalt membrane (VRAM). This product makes the joint more impermeable to water."

"Investment in J-Band is critical for the longevity of the asphalt."

"Products like VRAM help us extend the life of our pavements and spend less money on maintenance further down the line."
Justin Schneck
County Engineer for Morgan County, IN
"Samples taken from the VRAM section show improved density compared to those taken from the non-VRAM control section of the same project. It is anticipated that reducing air voids with VRAM will extend the life of the asphalt by up to 4 to 5 years."

"By using a VRAM for this project, we’re investing now to avoid expensive maintenance along longitudinal joints later. Specifically, we anticipate it will promote a better concrete-asphalt bond and keep the pavement from pulling away from that curb."
