Building Better Longitudinal Joints: How VRAM Enhances Notched-Wedge Paving

Paving a notched-wedge joint for traffic safety and reinforcing with VRAM
We all know how important and difficult it is to consistently achieve adequate density at longitudinal construction joints. These joints are typically the first place a pavement begins to crack or pothole, largely due to higher air voids compared to the rest of the mat. Forward-thinking agencies are increasingly turning...

Montana Highway 200 Trench Mill and Fill: Slot Paving Made Durable with a VRAM

Trench mill and fill, now with VRAM sprayed before the slot paving
The Problem  Miles of existing roads are plagued with longitudinal joint distress, especially if they have milled rumble strips. Centerline joint distress often needs re-paving far sooner than the rest of the pavement. There is a need for a better longitudinal joint repair system.  The Current Practice for Repairing Centerline...

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...

Sealing Joints Between Asphalt-Concrete Interfaces

VRAM is placed along the edge shoulder of a concrete lane so the asphalt-concrete interface can be sealed
Whenever asphalt pavement is laid along a concrete surface, such as a concrete lane, shoulder or curb, it is crucial to obtain a good bond. Bonding hot mix asphalt (HMA) to concrete is challenging as the HMA can pull away from the concrete creating an opening at the interface. These...

A Safer Way: Eliminating Centerline Density Testing

Worker cut by the core sampler samples of asphalt concrete on the road. Asphalt concrete cores close-up
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...
