State of the Art Survey on Confined Base Courses for Utility Airport Pavements

摘要

The report reviews the state-of-the-art in the use of confining methods for loose on-site materials as a stabilizing medium for utility airport pavements. Much field experimentation on expedient types of pavements is in progress by some Federal and State agencies, but a theoretical base has not yet been developed for predicting performance. It is shown that well developed specifications exist for membrane encapsulated soil layer systems, but none exits for sand-filled cellular systems. Present experimentation points to certain problems that must be corrected before sandfilled systems can be used for civil aircraft pavements. Recommendations are offered that could provide a predictive methodology. (Author)
