INSTRUCTORS:

Brian Killingsworth, P.E.

Purpose and Background

Concrete pavements may be used in a variety of applications including highways, streets, and parking lots. By using suitable design techniques and appropriate details a designer can develop an economic and sustainable concrete pavement cross section that will perform for many years.

This seminar will provide instruction on how to design and detail concrete pavements used in highways, streets, and parking lots by considering the traffic loads, soil conditions, and resulting pavement stresses. In addition to designing conventional concrete pavements, this seminar will provide introductions to innovative products such as pervious concrete, concrete overlays and roller compacted concrete.

Concrete thickness design will be presented from multiple design methodologies which includes both empirical and mechanistic-empirical procedures. Discussions of subgrade characterization and improvement as well as pavement jointing will also be provided. Concrete materials will be presented including discussions on strength, workability and durability. Additional detail will be provided on economic life cycle cost analysis (LCCA) and environmental life cycle assessment (LCA) of concrete pavements. Typical construction techniques for conventional concrete pavements and overlay as well as the unique techniques used for pervious and roller compacted concrete will be reviewed. Development and application of materials and construction specifications and the related quality control and acceptance tests will be highlighted in terms of meeting the design objectives.

This course is intended for civil engineers, geotechnical engineers, and public works officials involved in the design and layout of concrete highways, streets, and parking areas. Participants will leave the course with a better understanding of the analytical process used to achieve an optimized concrete pavement cross section that will perform as intended over the design life.

This seminar is being offered in partnership with the National Ready Mixed Concrete Association (NRMCA).
