Abstract:
This report describes: (1) investigation of time-sequence roughness data collected at GPS test sections to study trends in development of roughness, (2) comparison between International Roughness Index and Ride Number, (3) development of models to predict changes in roughness, (4) investigation of roughness characteristics of new flexible and rigid pavements built for the SPS program, (5) investigation of roughness characteristics of flexible and rigid pavements that were subjected to different rehabilitation strategies under the SPS program, and (6) recommendations for quality assurance and profiling frequency for the test sections
