| 摘要： | Extensive data were collected from 327 airfield pavement features at 12 U.S. Air Force bases. The data, which provided a wide range of information designs, materials, traffic, and climate, were used to develop PCI and key distress prediction models for both asphalt-concrete- and jointed-concretesurfaced pavements. Four satisfactory models were developed for predicting PCI for PCC and AC/PCC pavements, PCI for AC and AC/AC pavements, corner breaks in PCC pavements, and reflection cracking in AC/PCC pavements. Additional date were collected from 101 arefield pavement features at five of the Air Force bases originally surveyed to evaluate the four prediction models. The evaluation showed that the PCI prediction models are satisfac-sight pavement features/However,verification of the corner break model showed that it has a high standard deviation of prediction. Evaluation of the models for each of the five bases showed that predictions for seme of the bases were much better than orhers,possibly because some of the material properties,climatic factors,and traffic conditions in concluded that localixed modeling could previde much more accutale predictions. |
