摘要
针对沥青路面水损害问题,运用轴对称有限元方法分析了不同等级轴载作用下沥青路面层间孔隙水压力的变化规律。研究结果表明,孔隙水压力将造成路面层间的严重冲蚀,导致沥青与集料过早剥离而诱发水损害,而超载将加速这一进程。
This paper is aimed specifically at moisture damage issue of asphalt pavement, and the axis-symmetric finite element method is adopted to analyze the variations of interbedded pore water pressure of asphalt pavement under different load condition. The study results revealed that pore water pressure erodes away the pavement, induces stripping of the asphalt from aggregate and causes moisture damage to the asphalt pavement, and over-load advances the course.
