by the density test of blow-drying and stoving of non-aridity core sample from asphalt pavement, the bulk volume relative density and compactness can be calculated under different test conditions.
it is also common to measure the weight of the sample when immersed in the liquid. the grain and bulk volume can then be calculated as in the buoyancy method.

porosity is defined as the ratio of the void space in a rock to the bulk volume of that rock multiplied by 100 to express in percent.
孔隙度定义为巖石内的孔隙体积占巖石总体积的百分率。
a technique for measuring the bulk volume of a core sample by observing the displacement of mercury in a chamber.
