Abstract:

[ Objective] To improve the existing intelligent compaction quality evaluation methods and indicators for asphalt pavement. [ Method] An intelligent compaction system for asphalt pavement was constructed by using acceleration sensing and positioning systems. A longitudinal zoning compaction scheme suitable for asphalt pavement was proposed. Based on the vibration compaction values obtained with analysis and calculation on acceleration signals, a relation model between vibration compaction values and asphalt pavement compaction degrees was established. The standard deviation rate, nearest neighbor index, and coefficient of variation indicators were proposed to comprehensively evaluate the asphalt pavement compaction quality. [Result] With the increase of compaction times, the variation amplitude of vibration compaction mean value gradually decreases. The asphalt pavement maximum compaction times can refer to the variation on vibration compaction value. There is a good correlation between vibration compaction value and compaction degree of asphalt pavement, with a correlation coefficient of 0. 72. [Conclusion] The standard deviation rate considers the differences between vibration compaction value of unqualified area and target value. The nearest neighbor index considers the dispersion degree of unqualified area, and the coefficient of variation considers the variation amplitude of unqualified area. They are respectively applicable to evaluate the compaction quality of asphalt pavement compaction degree, uniformity degree, and stability degree, optimizing the existing intelligent compaction quality evaluation methods for asphalt pavement. ©The Author(s) 2025.
