TRB releases research on geosynthetics and pavement performance

News | July 31, 2017 | By:

National Cooperative Highway Research Program (NCHRP) of the Transportation Research Board (TRB) has made available online the document “Quantifying the Influence of Geosynthetics on Pavement Performance.” The research report develops a methodology for quantifying the influence of geosynthetics on pavement performance for use in pavement design and analysis.

This project focused on the use of geosynthetics in unbound base/subbase layers or as a base/subgrade interface layer for flexible and rigid pavements. The AASHTOWare Pavement ME Design software provides a methodology for the analysis and performance prediction of pavements. However, use of geosynthetics in pavement layers and their influence on distress models have not been included in Pavement ME Design.
