Description： It is suitable to determine theoretical maximum specific gravity and density of asphalt mixture using vacuum method. The determination is used to design the asphalt mixture ratio and calculate the percentage of void and the degree of compression for investigation of road situation or quality management of road surface construction. But it is not suitable for the water absorption rate of porous mineral aggregate asphalt mixture more than 3%.
