机场水泥混凝土道面夹层材料性能研究

为了研究不同夹层材料对双层道面结构中上、下板的影响,采用室内双层小梁试件试验模拟双层道面的状况。小梁采用抗弯拉强度试验的标准强度,采用同一种配合比同时进行拌合、振捣、成型、养护,结果表明两根小梁试件的抗弯拉强度和抗弯拉弹性模量是相等的。

Study on Performance of Interlayer Material on Cement Concrete Pavement of Airfield

In order to study the influence of different interlayer materials on the upper and lower plate of double-layer pavement structure,this paper simulates the condition of double-layer pavement through indoor test with double-layer small girder test piece.Small girders shall be of standard strength of tensile strength test and shall be mixed,vibrated,formed and maintained at the same time with the same mixing proportion.The result indicates that two girders have equal tensile strength and elastic modulus in ten...
