TRB’s National Cooperative Highway Research Program (NCHRP) Synthesis 388: Pre-Overlay Treatment of Existing Pavements explores current pre-overlay treatment practices of state departments of transportation for both hot-mix asphalt and portland cement concrete pavement structures. The report is designed to help pavement management and pavement design groups in their selection of pre-overlay treatments.
Appendix B–Distress and Appendix C–Questionnaire Response Summaries to NCHRP Synthesis 388 are available online.
