When the crew violates certain asphalt paving fundamentals, defects in the asphalt layer usually appear. A crew that is well-trained in paving fundamentals and takes the time to control the fundamental aspects of paving will generally be successful. In Unit 3, "Fundamentals of Paving," these basic principles are described.
