Permanent deformation behavior of unbound granular materials and rutting model development
… was found to produce inadequate rut estimates in unbound aggregate base/subbase layers by discounting the contribution of stress state from the original Tseng and Lytton (1989) model. This research study was aimed at developing a new permanent deformation prediction model that would properly take …

Permanent Deformation Behavior of Airport Flexible Pavement Base and Subbase Courses
… flexible pavement test sections in the granular base and subbase layers, designated as NAPTF P209/P154 base and subbase according to FAA's construction specifications. To account for the rutting performances of these substantially thick granular layers, a comprehensive set of repeated load …

An Investigation of the Optimal Sample Size, Relationship between Existing Tests and Performance, and New Recommended Specifications for Flexible Base Courses in Texas
The purpose of this study was to improve flexible base course performance within the state of Texas while reducing TxDOT’s testing burden. The focus of this study was to revise the current specification with the intent of providing a “performance related” specification while optimizing sample sizes …
