Product Introduction
I. The vacuum saturation test of asphalt mixture is one of the necessary equipment for calculating the void ratio. The maximum density of asphalt mixture is an indicator in theoretical research. It indirectly reflects the internal porosity of the mixture material. The smaller the density itself, the larger the porosity. Since it takes a long time for water to permeate into the interior under normal pressure, a vacuum test in the soaking water is required. The air in the voids of the mixture and its test blocks is pumped out, and the voids are filled after water infiltration. After the experiment, the increased weight of the test piece is weighed to calculate the water absorption rate and the void ratio.
