Rehabilitation of Asphalt Concrete Pavements: Initial Evaluation of The SPS-5 Experiment-Final Report

Appendix B. Construction Data Summary

Appendix B contains a summary of the construction data available for each project as of the approximate time of this report, which was 1999-2000. Thickness data were from three sources. The first source was the TST_L05B table, which contained the values most representative of the material that was actually placed on the test section and the pre-existing pavement structure. The second was the SPS5_LAYER table, which included thicknesses that should be the same as those provided in the TST_L05B table. However, in most of the data shown, these thicknesses were not the same. The third source was the SPS5_LAYER_ THICKNESS table. These data were obtained from elevation measurements taken on the projects after the placement of each layer of overlay.
