The asphalt surface your crews put down is the finished job your clients see, and this session will help paving contractors identify potential problems in the asphalt mat so they can provide a better end product for their customers. You’ll learn how to differentiate among four primary problem areas: the properties of the mix itself (checking, shoving, rutting, moisture content, bleeding); site related conditions (milling, minimum layer thickness, tack coat application, soft subgrade); equipment related problems (screed settings, surface shadows, streaks); and long term durability issues (raveling, sliding, fatigue cracking, delamination, drainage structures). You will learn what you can do to prevent these problems from happening (and correct them when they do occur). You’ll take home information you can use to help your crew construct the best-looking, longest-lasting asphalt mat possible.
