| Abstract |
Test constructions were performed at 3 sites to investigate ways for maximizing performance of geogrid-reinforced asphalt pavements known to reduce reflection cracking and rutting. Problems during construction operation which can affect bonding shear strength of the geogrid-reinforced asphalt pavements were defined and the construction conditions were intentionally made during the test constructions. Both immediately and 1year after the test constructions, cores were obtained from positions with good and bad construction conditions and then bonding shear strength tests were performed to be compared each other. Rules to be kept at construction sites were suggested to improve performance of the geogrid-reinforced asphalt pavements. |
