INFLUENCE OF GEOSYNTHETIC PLACEMENT POSITION ON THE PERFORMANCE OF REINFORCED FLEXIBLE PAVEMENT SYSTEMS

The use of geosynthetics for the design and construction of reinforced flexible pavements has been complicated by the importance of certain variables known to influence subsequent pavement performance. One such variable is the vertical placement position of the geosynthetic within the base course layer. Results of laboratory-scale model pavement experiments are presented which further show the importance of this design parameter. Two sections reinforced with the same geogrid product are compared to a similar section without geosynthetic reinforcement. Measurements of stress and strain in the pavement system layers are presented and used to quantify the system's mechanical response that was responsible for the levels of reinforcement benefit observed in the test sections.
