Abstract
This study performed an experimental investigation of asphalt concrete with and without fiberglass geogrid reinforcement, using specimens in the laboratory and in situ. A 100kN/m fiberglass geogrid was used. The results showed that with the fiberglass geogrid reinforcement, the flexural strength of the asphalt increased by 24.82%, deformation was significantly reduced, and the elastic modulus did not improve significantly. In addition, using the Hamburg Wheel Tracker test, the fiberglass geogrid reinforced asphalt samples had a 7.41%reduced rutting depth. Finally, two segments in situ were also tested showing that the flexural strength of asphalt concrete increased by 24.27% and the structural strength of the pavement increased by 25.24%. These results show that pavement structures are significantly improved when reinforced with fiberglass geogrid.
