沥青混合料施工均匀性的关键性评价指标及方法研究

Research on Key Evaluation Index and Method of Construction Uniformity of Asphalt Mixture

针对沥青混合料VV、VMA、VFA等体积指标相对于原设计波动较大的现状,采用沥青含量、VV、VMA三大指标评价沥青混合料均匀性的方法及相应的评价标准可靠性较高,具有一定的实用价值,且采用折线图和柱状图分析三大指标抽检结果的方法直观、便捷。

Facing on the condition that the asphalt mixture volume indexes VV, VMA, VFA fluctuate much with the primary design, the method and corresponding appraisal criteria which combines 3 indexes （asphalt content, VV and VMA） to evaluate the uniformity of asphalt mixture have higher credibility and practical value. The method adopting line chart and histogram to analyze random spot check results of 3 indexes is obvious and convenient.
