摘要
鉴于目前高等级公路结构承载能力不足以满足飞机直接起降的要求,一般需在原路面上加铺一层结构层以提高路面的整体承载力。通过对设计的四种不同加铺层材料进行马歇尔试验、单轴压缩试验、劈裂试验和冻融劈裂试验、车辙试验和构造深度试验等,以确定加铺层材料的基本性能参数,并从性能、经济和便于维护角度出发,找到了满足飞机起降要求的加铺层材料,可供今后的实际应用参考。
Because the bearing capability of a high-grade pavement is still not good enough for airplane taking-off and landing, a structure layer must be added onto the high-grade pavement in order to improve its bearing capability. The mechanical characteristics of four kinds of over-laid materials are studied by the Marshall test, single-axial compression test, split test, freeze-thaw split test, wheel-rutting test and texture depth test. From the angles of performance, economy and easy maintenance, the over-laid materials are found able to meet the needs of airplane taking-off and landing. The result of the research above may serve as a reference for practical applications in the future.
