Quality seal coating requires both science in design and skill in application. This video shows emulsion and aggregate spreaders in action and explains the project management necessary to maintain an efficient seal coating operation.
The video discusses the differences between cracking filling and crack sealing and between routing versus sealing. Computer animation helps illustrate key concepts.
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.
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.
