Performance of geocomposite membrane in pavement systems
Geosynthetics are recognized as materials that may significantly improve the performance of flexible pavements when appropriately used. However, its contributing mechanism is still unclear. The pavement research at the Virginia Smart Road has been designed to better understand the geosynthetic mechanistic contribution. Twelve flexible pavement sections with different designs, wearing surfaces, and drainage capabilities were built and instrumented for stress and strain measurements in all layers as well as for environmental effects (temperature, frost, and moisture). A geocomposite membrane (a low modulus polyvinyl chloride (PVC) layer sandwiched between two woven geotextiles) was installed in two sections to quantify its effectiveness as a moisture barrier and as a strain energy absorber. Initial analysis of the collected data from embedded instruments showed the ability of the geocomposite membrane to significantly reduce the transversal tensile strain in the supporting layer. Although this behavior is coupled with greater deformation in the geocomposite membrane, the resulted deformation is recoverable.
