    • Abstract:
      This report documents the construction and initial evaluation of the HaTelit 20/9 Polyester Geogrid material placed at mid-depth of the HMAC overlay of the Broken and Seated PCC pavement on Interstate 10, west of Lake Charles, LA. The roadway has an ADT of 43,400 vpd with 20% of these being heavy trucks. This experimental feature is expected to reduce and limit the severity and extent of pavement distress.

      The material was placed between the two lifts of Binder Coarse, with an AC tack coat placed on the first lift prior to rolling the material in place. The material was also physically secured by nailing it to the previous lift. The remaining Binder along with the Wearing Coarse was placed over the material.

      The serviceability of the pavement increased after construction to an average of 4.2 PSI. Cost figures are provided and can be compared to the control sections. The performance of this experimental feature will be monitored over the next three (3) years and will be compared to the two control sections.
