Abstract: 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.
