摘　　要：沥青路面现场压实度或空隙率的大小直接影响到沥青路面的抗水损害能力。但对AC13、AC16、AC25三种级配类型各自50组级配的沥青混合料,在不同制样方式下的密度和空隙率研究结果表明,以现场芯样密度基于试验室标准密度获得的压实度或空隙率与沥青路面实际的压实度或空隙率存在2%的误差,导致沥青路面竣工压实质量的评定失真。因此,建议采用现场芯样密度以试验室标准密度评定沥青路面的现场压实度(或空隙率)时应考虑折减2%(或增加2%)作为竣工验收最终结果。The in-site degree of compaction or voids for asphalt pavement directly influences the water failure resistance to asphalt pavement. But the research results for the density and the voids of asphalt mixtures with each a 50 groups of grade for AC13, AC16 and AC25 respectively at different experiment ways show that the in-site degree of compaction or voids based on the bore-in-site sample density to laboratory criterion density has an error of 2% with the actual in-site degree of compaction or voids of asphalt pavement that results in the evaluation of compaction quality for finished asphalt pavement not to be true to the original. Therefore, it is proposed that the completion inspection for finished asphalt pavement based on the bore-in-site sample density to the laboratory criterion density should give 2% discount for the in-site degree of compaction （or increase 2% for the in-site voids） as a final result.
