Abstract:

The use of lightweight aggregate in the production of plant mixed asphalt paving materials requires consideration of specific guides to maximize the success probability of design, construction and maintenance of this surfacing material. The need, indeed, the demand for long term high friction pavement surfaces increases with the ever-increasing volume of traffic on the nation's highways. This need can be answered by following the guidelines presented. Problems have arisen in many instances in the past wherein lightweight aggregates have been used in plant mixed asphalt paving mixtures. Aggregate selection and evaluation, mixture design, hot plant operations, transport, laydown and compaction considerations plus maintenance of thin overlays made with lightweight asphalt aggregate mixtures are covered in detail. Further, the author discusses certain pavement distress mechanisms. and how to identify and prevent or correct these problems.
