  The inadequacy of many existing roads due to rapid growth in traffic volume provides a motivation ; for exploring alternatives to existing methods of constructing and rehabilitating roads. The use of ; geosynthetics to stabilize and reinforce paved and unpaved roadways offers one such alternative. ; Many studies were conducted to evaluate the improvements associated with geogrid reinforcement of ; pavements. It is widely believed that geogrid reinforcement of roadways can extend a pavement¿s ; service life and/or reduce the pavement¿s structural thickness. ; LTRC Technical Summary Report 450 ; September 2009 ; Several design methods were proposed for flexible pavements with geogrid reinforced base layers. ; These methods were either based on empirical or analytical approaches. Empirical design methods ; are usually based on obtaining a performance level from a laboratory model test, which is then ; extrapolated to the field conditions for design application. The geogrid reinforced design methods ; based on analytical solution do not address all the variables that affect the performance of these ; pavements. This report is part of a research study on evaluating the benefits of geogrid reinforcement ; of base layer in flexible pavements. It presents the findings from laboratory triaxial tests and finite ; element analyses. Another report of this study will present the findings from large-scale cyclic plate ; load tests on ALF sections and sections built inside a test box.
