| Abstract: | For highway use, analysis is made on the impact characteristics of overloaded and long-steep slope on asphalt concrete pavement. The definition standard and the conversion formula for this slope are provided. The long uphill and downhill slopes are respectively conducted with a mechanical analysis. The temperature and equivalent characteristics are used to explain the tormations of damages. |
