Protect Pavement Density at the Joint
For the June toolbox tips, we’ll pay close attention to quality control/quality assurance. Controlling quality starts with best practices. When building the joint, workers can sabotage your success by raking material away or casting material across the mat instead of leaving material in place. You actually want a little extra material bridging the joint for the roller to mash down in there.
Teach the lute man and rakers to gently nudge or bump the edge of the mat with the lute or the back of the rake when working the joint or creating an edge. Don’t let them bump so hard they knock material loose. Don’t let them cast material across the mat for material and temperature segregation problems later.
If you have excess material at the joint, scoop it to the site to be picked up with a shovel. That material can be collected in a bucket for recycling later.
