Composite Concrete Pavements - Wet on Wet

  • Jan 13, 2011 (10:30 - 12:00 pm CT; 9:30 - 11:00 am MT)
    Webinar (desktop or laptop access)


Composite pavements consist of two distinct pavement layers designed and constructed as a new pavement, and not as a rehabilitation strategy. These systems entail a higher quality wear surface over a lower quality, or recycled base layer. Two systems currently under evaluation include hot mixed asphalt (HMA) over a Portland cement concrete (PCC) pavement and a PCC over PCC (wet-on-wet) pavement. Composite pavements provide strong, durable, safe, smooth, and quiet pavement surfaces, and they are expected to be long-lasting, requiring minimal maintenance over a long time period.

This webinar will discuss composite pavement technology being investigated through two research projects at the Minnesota Road Research Facility (MnROAD), a real-life accelerated pavement test facility near St. Paul, MN. Topics to be covered include test section construction and instrumentation activities, early laboratory and field performance, non-destructive testing evaluation techniques, performance predictions using the Mechanistic Empirical Pavement Design Guide (MEPDG), and a contractor’s theoretical cost-estimating scenario.
