The effect of the size of particulates and pressing pressure on porosity ratio has been studied.
在大量实验结果的基础上探讨了最优保压压力曲线的设定。
Red soil is a widely regional special soil which has high porosity ratio, high water content, high strength and low compressibility.
红土是一种广泛分布的具有高孔隙比、高含水率、高强度和低压缩性的区域性特殊土。
Therefore, the porosity ratio is controlled in the smaller level, which is favorable to control the water damage of the urban road asphalt pavement in China.
因此，将空隙率控制在较小水平，有利于控制我国城市道路沥青路面的水损坏。
