| 摘 要： | 动水压力模拟试验方法是提高沥青混合料抗水损害性能需要研究的基础理论问题之一.在设计以气压传递激发沥青混凝土孔隙中水压动态变化的试验装置的基础上,通过封闭圆柱形试件的侧壁和在试件底端构造蓄水空间以引导水在孔隙中向下渗流,形成定向冲刷模式.经有限元计算发现随试件深度增加水压减小,说明半刚性基层沥青路面比排水基层沥青路面承受...

| Abstract: | The simulation method of dynamic water pressure is one of the basic theories which should be researched to improve the water damage resistance of asphalt mixture.On the basis of designing the test system which generates dynamic water pressure in the voids of asphalt concrete by compressed air,the cylindrical asphalt concrete specimen,which has a space on its bottom and covered with epoxy resin glue on its lateral,was made to induct the water flow oriented through asphalt concrete voids to the established sp... |
