Casting Material Across the Mat Leads to Segregation
We all know that casting material from an overfed longitudinal joint across the fresh mat leads to segregation and poor density, so why are laborers still doing it? Train them to stop that.
Now, as we’re gearing up for the 2022 paving season, take the morning tailgate talk to remind laborers that breaking down the joint with manipulation by lutes and rakes that spread cooling dribbles of mix across a smooth mat on which the screed has already achieved 80% or more compaction is a poor paving practice.
If the laborer needs something to make him look busy, teach him how to gently bump the joint with the lute or the flat head of the rake without knocking the edge down.
If you see a co-worker casting mix across the mat today, speak kindly to suggest he stop that practice and perform a different activity to assist the team get a smooth, compactible surface.
