ABSTRACT: Being a parameter of concrete antifreeze evaluation, air void spacing factor had got much more attention.
作为评价混凝土抗冻性的参数之一，混凝土气泡间距系数越来越受到重视。
Tests show that clay in fine aggregate affected the water stability of asphalt mixture markedly; the permeable critical air void is 7.
试验表明，集料泥土污染对沥青混合料水稳性影响显著，沥青混合料的渗水临界空隙率为7。
Tests show that clay in fine aggregate affected the water stability of asphalt mixture markedly; the permeable critical air void is 7.5?
试验表明，集料泥土污染对沥青混合料水稳性影响显著，沥青混合料的渗水临界空隙率为7.5%。
This paper discussed a method to measure the air void parameters of RCC using high resolution flatbed scanner and image analysis software.
本文探索了采用高分辨率平板扫描仪配合图像分析软件进行碾压混凝土气泡参数的测定。
The paper proposed a new parameter "reserved air void" based on the Bailey Method, by which to design mix proportion of porous asphalt mixture.
本文基于贝雷法提出采用“预留空隙率”参数设计排水性沥青混合料的方法。
Air void is one of the key indexes in the quality control of asphalt pavements. It is more strictly restricted to use epoxy asphalt concrete on deck pavement of long-span Bridges.
空隙率是沥青路面施工质量控制中的关键技术指标之一，由于环氧沥青混凝土大多用在大跨径钢桥面铺装中，因此，对空隙率的要求更为严格。
