摘要：

A forensic investigation was conducted on four sections of Ohio Test Road developing early longitudinal cracks and rutting. From various non-destructive and destructive tests, it was determined that the longitudinal cracks were top-down cracks initiated by segregation of surface layer asphalt mixtures at the time of construction. Rutting was developed at the base layers and subgrades due to weakening in the presence of excessive moisture which was, in turn, caused by higher than normal air voids in the segregated asphalt mixes.
