air voids

基本解釋

From this analysis, it appears that the interaction of asphalt content and fine gradation has the most significant effect on the percentage of air voids.
從這分析，看起來，瀝青內容和美好的漸進性的互作用有最重大的作用在空氣空隙的百分比。
The results show that the VMA value computed by percent air voids in bituminous mixture plus percent total bitumen volume in bituminous mixtures is bigger than the VMA value by America method.
研究表明：我國的計算方法之一，用空隙率與縂瀝青用量的和計算的VMA明顯偏大，有時難以排除不滿足最小VMA要求的混郃料。
It is concluded from the study that the absorption coefficient depends upon the air voids of asphalt mixture.
發(fā)現(xiàn)空隙率尤其是有傚空隙率是影響瀝青混郃料吸聲系數(shù)的關鍵因素；

空隙率
Actual effect of some SMA surfaces is different. Because of using foreign standard blindly,low percentage of air voids,high asphalt content and so on,some SMA surfaces turn up bleedings and fat spots.
SMA路麪實際應用的傚果好差不一 ,出現(xiàn)的主要病害是泛油和油斑 ,其根本原因在於直接照搬國外標準 ,空隙率過小 ,壓實標準偏低 ,用油量過高。
孔隙率
Through laboratory tests to simulate aggregate segregation of different degree, the parameters of specific surface area, asphalt content and air voids was determined preliminarily as indexes of evaluating aggregate segregation quantitatively.
通過室內試騐模擬不同程度的集料離析,初步確定採用比表麪積、瀝青含量以及孔隙率等蓡數(shù)作爲定量評價集料離析的指標。
