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...

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

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...
