Selected papers from the International Airfield and Highway Pavements Conference 2021, held virtually June 8-10, 2021. Sponsored by the Transportation & Development Institute of ASCE.This collection contains 17 peer-reviewed papers on pavement design, construction, and condition evaluation.Topics include: pavement design methods and advanced modeling techniques for highway pavements; construction specifications and quality monitoring; accelerated pavement testing; rehabilitation and preservation methods; pavement condition evaluation; and network-level management of pavements. This proceedings will be of interest to engineers, designers, project/construction managers, researchers, and contractors involved in the design and construction of airfield and highway pavements.

A method for estimating the life of rigid airfield pavements is presented which is applicable for any ty aircraft traffic on all types of rigid pavement including overlays. The basic concept of the method presented is that any rigid pavement will withstand a certain number of stress repetitions before it cracks. The number of stress repetitions is dependent upon the magnitude of stress which is in turn dependent upon such things as: magnitude of load, gear configuration, traffic distribution, pavement strength, and foundation. All are considered in the method presented; an example of the use of the method is shown as well as three classical examples considering special problems. (Author).

The paper was organized to present the various factors which influence the current design criteria with a brief explanation of how the numerical values of each was derived.
