Abstract: A mathematical model was developed to design a pavement section reinforced with a geotextile or related product to span a void. A full scale field test was conducted to verify the model. Twelve test sections were constructed with three different materials and three different void widths. The voids were constructed by digging a trench in the fall and filling it with water which was allowed to freeze during the winter. In the spring each section was covered with 30 inches (0. 76m) of fill and the ice was allowed to melt. Following thawing each test section was trafficked with a loaded, dual wheels tandem axle, dump truck. Each of the test sections failed to carry the full load successfully. However the test was a success because it verified the model and led to a better understanding of the materials used and their behavior in this application.
