| 摘 要： | 以依七高速公路沥青路面施工为依托,对沥青混凝土路面压实度的质量控制标准进行了探讨。结果表明：采用马歇尔标准密度和最大理论相对密度双重标准进行控制,能够真实、有效的反映路面实际压实情况。当芯样空隙率大于设计空隙率4．12％时,以马歇尔试件为标准密度计算的压实度值可能出现超百假象,此时试件不能真实的反映沥青路面的压实状态,因此建议按照两项质量控制标准相一致的原则,通过数理统计的方法对K1值进行线性回归,用回归后的压实K′2度表示此时的压实度。

| Abstract: | Based on the asphalt pavement construction of Yi-lan and Qi tai-he highway, quality control standards on compaction degree of asphalt concrete pavement was discussed. Results show that, with double standards of Marshall standard density and the theoretical maximum relative density, the actual compaction condition of pavement can be truly and effectively reflected. When a core sample porosity is 4. 12% greater than design porosity, the compaction degree value calculated by Marshall specimens may shows a false illusion of over one hundred, which can not truly reflect the real compaction state of the asphalt pavement. Therefore, it is recommended to calculate the compaction degree with the principle of two quality control standards be consistent with each other. Through the method of mathematical statistics, linear regression can be conducted to K1 , and the compaction degree of K′2 after regression is the real value. |
