摘要
依托上海虹桥机场东跑道第4次加铺工程,针对机场道面多次加铺后存在的沥青面层过厚、老道面材料性能严重老化等突出问题,以有限元数值分析方法为基础,建立了基于沥青面层疲劳开裂、水泥板疲劳开裂和轮辙控制3个指标的道面结构合理性分析方法。研究成果对完善中国沥青道面加铺设计方法和指导类似工程的开展有重要意义。
Relying on Shanghai Hongqiao Airport East Runway the fourth overlay project,contrary to the airport pavement with multiple overlay existing outstanding problems that asphalt layer is too thick,and the material properties of existing pavement severely aging,based on the finite element numerical analysis method,established pavement structure rationality analysis method based on three index of asphalt surface fatigue cracking,fatigue cracking of the concrete surface and rut control.The research have the important meaning for improving design method of asphalt pavement overlay in our country and guiding similar projects to carry out.
