Lochner, Inc.US Transportation CollectionPhase I and II of this study tested approximately 1500 rehabilitated pavements (asphalt and PCC)throughout the State. These pavements ranged from 5 to 15 years old and were intended to develop asnapshot of how various rehabilitations were performing. Data for each site consisted of office data(asbuilts), field testing (FWD, distress and coring) and laboratory testing (Rice, gradation, etc.). Datawas provided in an Access database. Indices were created for structural, roughness and distress as anevaluation tool to compare sections. Initial analyses using these indices were made on RAP and RACsections throughout the State which showed that the data provides a basis for comparing strategies
