TRB’s National Cooperative Highway Research Program (NCHRP) Web-Only Document 159: Supporting Materials for NCHRP Report 673 contains the final report on the project that developed NCHRP Report 673: A Manual for Design of Hot Mix Asphalt with Commentary and Appendixes C through F to the report.

NCHRP Report 673 contains a mix design manual for hot-mix asphalt (HMA) that incorporates the many advances in materials characterization and mix design technology developed since the conclusion of the Strategic Highway Research Program (SHRP).

The titles of the appendixes included in Web-Only Document 159 are as follows:
•Appendix C: Course Manual
•Appendix D: Draft Specification for Volumetric Mix Design of Dense-Graded HMA
•Appendix E: Draft Practice for Volumetric Mix Design of Dense-Graded HMA
•Appendix F: Tutorial
