ODOT’s US-6 Displays the Power of VRAM to Seal Longitudinal Joints

Void reducing asphalt membrane centerline joint of a road
Crack sealing is an important practice for agencies to prevent further damage to already emerging cracks in a pavement structure. The longitudinal construction joint is commonly crack-sealed, because it is one of the most vulnerable spots in a road.   Despite crack sealing, the longitudinal joint is often the first location...

Paving Indiana’s Future: VRAM Joins the State Spec

INDOT Adopt VRAM
As of April 16, 2025, INDOT has released a state design memo specifying the use of Void Reducing Asphalt Membrane (VRAM) for Asphalt Paving in projects with category 2, 3 and 4 surface mixes.  Design Memo No. 25-10: Void Reducing Asphalt Membrane (VRAM) for Asphalt Paving  To: All Design Personnel...

Preserving Rumble Strips: Real-World Reviews of VRAM for Rumble Strip Longevity

J-Band
Rumble strips play a critical role in keeping drivers alert and roadways safe. However, they are typically constructed over or near longitudinal joints, the part of the pavement that is already vulnerable to water intrusion and early deterioration. To reinforce rumble strips, their pavement foundation—the longitudinal joint area—needs to be...

Northern Ohio State Route 168 Exceeds Expectations with VRAM

Large gap above the centerline joint
The most vulnerable part of any new asphalt pavement is typically the longitudinal construction joint. Achieving adequate density at the intersection of pavement lanes is notoriously more difficult than elsewhere on the mat. Lower density translates to more air voids, allowing water and air intrusion to prematurely degrade the pavement.  ...

A Solution to Joint Density Failure: J-Band + Rapid Penetrating Emulsion (RPE)

J-Band
Achieving adequate density at the longitudinal joint of a road is challenging. Well-constructed joints typically have 1-2% lower density than the mat, while poorly constructed joints can be 5-10% lower. When the density at the joint is considerably less than that of the mat, the joint area has more air...

How J-Band Revolutionizes Road Construction by Fixing Longitudinal Joint Failure

Truck drives down the road, spraying J-Band on the centerline
https://youtu.be/wpk66c6BCk8?si=oAjy6aaYDwx2Ix3Y For decades, road managers have tried to find a reliable fix for the consistent weakness in the center of every road. Over time, longitudinal construction joints are the first part of the pavement to crack and fail. Topical solutions have not been able to address the issue completely and...
