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

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....

A Safer Way: Eliminating Centerline Density Testing

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...

How to Test the Permeability of Your Roadway

Have you ever wondered why your longitudinal joint is cracking and deteriorating over time? It’s probably because the pavement joint is highly permeable, which allows elements such as water and air to seep into the pavement and break it down. Pavement joints are traditionally hard areas to obtain density, leading...

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

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...
