| 摘要： | The study pertains to 163 miles of 4 to 8-lane asphalt concrete (AC) pavement that developed a considerable amount of premature distress. The history, performance, and climatological data for Route 15 from Cajon Pass to the Nevada state line were studied. A considerable amount of coring and testing was done to determine several physical properties of the top 3 inches + or - of the AC. Pavement deflection and traffic data were also obtained for the investigation. It was concluded that most of the factors studied could not be assigned as the cause of the premature distress that occurred. It was recommended that careful attention be given to the amount of minus 200 material in the design mix vs. the job mix, that the target asphalt content not be reduced from that determined in the lab unless supported by job-specific data, and that considerable effort be expended to protect against the placement of moisture sensitive asphalt concrete. |
