Why is this a priority for the State/County/City? : The time is now to fully implement the responsible utilization of geosynthetics during pavement design and construction. Two national projects, one administered by the National Cooperative Highway Research Program (NCHRP) and the second, a Transportation Pooled Fund (TPF) project are will be finishing up shortly. These projects were created to resolve uncertainty, facilitate greater acceptance and quantify the influence of geosynthetics on pavement performance “Quantifying the Influence of Geosynthetics on Pavement Performance” http://apps.trb.org/cmsfeed/TRBNetProjectDisplay.asp?ProjectID=2949 and “Relative Operational Performance of Geosynthetics Used as Subgrade Stabilization” http://www.pooledfund.org/Details/Study/479. These projects will produce a methodology for quantifying the influence of geosynthetics on pavement performance for use in pavement design for both flexible and rigid pavements.
