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...

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...

Every road manager knows that longitudinal joints are typically the first part of the pavement to fail, but why does this happen and how can it be stopped?   Longitudinal joints are the weakest point of the pavement because they have a higher concentration of air voids than the rest of...

How Springfield, Illinois’s SR-29 Has Stood the Test of Time

IL-29 Close Up
How often are you repairing major roads? After years of wear and tear and damage from the elements, longitudinal joints are typically the first part of a pavement to fail. Water seeps into air voids at the most permeable part of the road and leads to premature maintenance and repair....
