Abstract
Intelligent compaction technology is a new pavement compaction control technology. In order to research the reliability of intelligent compaction technology for compaction degree evaluation of asphalt pavement, the intelligent compaction technology was used to compact the asphalt mixtures of Ji-shuang highway project (SMA-13 for upper layer of the pavement and AC-20 for middle layer of the pavement). The vibrating compaction value (VCV) was detected by the intelligent compaction system continuously during the rolling process. Then the compaction degree of the two pavement layers after the last vibration rolling was measured by the non-nuclear density gauge. Finally, the relationship between VCV value and compaction degree of the two pavement layers was fitted by the least square method. Results show that the compaction uniformity of asphalt pavement is good through intelligent compaction. The VCV obtained from the intelligent compaction has a good correlation with the compaction degree.
