Composite Pavement Systems, Volume 1: HMA/PCC Composite Pavements

TRB’s second Strategic Highway Research Program (SHRP 2) Report S2-R21-RR-2: Composite Pavement Systems, Volume 1: HMA/PCC investigates the structural and functional performance of surfacing a new portland cement concrete (PCC) pavement layer with a high-quality hot mix asphalt (HMA) layer.

The second report in the series, Composite Pavement Systems Volume 2: PCC/PCC Pavements,explores the structural and functional performance of placing a relatively thin, high-quality PCC surface atop a thicker PCC layer.

Both of these new composite pavement systems have shown great promise for providing strong, durable, safe, smooth, and quiet pavements that need minimal maintenance.

The appendices to the two-volume report provide additional detail, understanding, and history on HMA/PCC and PCC/PCC pavements.

The project that produced this report also produced SHRP 2 Report S2-R21-RW-1: 2008 Survey of European Composite Pavements.

SHRP 2 Renewal Project R21 has also produced sample specifications related to three experimental composite pavement sections in Minnesota, as well as proposed revisions to AASHTO’s Mechanistic-Empirical Design Guide, Interim Edition: A Manual of Practice, which address newly constructed composite pavements.
