Pavement Repair: Do the Right Thing at the Right Time
Using nontechnical terms, pavement material samples and other aids, a moderator explains how engineers gather data on pavement and underlying soils, then discusses the factors considered in making rehabilitation decisions.
Weather and Loads: The Effect They Have on Roads
While focusing on how pavement materials are affected by weather and loading, this video covers the basic concepts of pavement engineering, including fatigue, bearing capacity, and thermal expansion. It is a technical topic, designed for a general audience, with tabletop cross-section models to illustrate principles. Damage caused by overweight vehicle loads is also discussed.
