Large-Scale Laboratory Testing of Geosynthetics in Roadway Applications

Geosynthetics laid out and ready for placement of base course

The main objective of this project is to characterize the performance of geosynthetic-reinforced test sections when compared to an unreinforced case to assess benefit in terms of a reduction in the base course thickness, an extension of the life of the pavement, or the strengthening of the individual pavement layers. This objective will be achieved through the construction of a single test track containing three test sections, a detailed analysis and synthesis of the results, and the evaluation of an analytical design tool to be used by pavement engineers to design geosynthetic-reinforced pavements.
