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.
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.
