Balloon Density Apparatus
Balloon Density Apparatus
Standards: ASTM D2167, AASHTO T205
Balloon Density Apparatus is used to determine the in-situ density of compacted or firmly bonded soils.
The HR-S7700 consists of a graduated cylinder 1596 ml capacity, housed inside an aluminium guard, a reversible rubber aspirator pump and a density plate 9” square. The principle of operation is similar to the sand replacement but the hole is filled by a rubber balloon where water is pumped. The amount of water can be easily determined by the graduation of the cylinder. Rubber balloons should be ordered separately.
The HR-S7705 is 3000 ml capacity. A metal cylinder is filled with water which is then pumped into a rubber membrane mounted on the base of the cylinder. The water pressure is controlled by a pressure gauge and the volume of the balloon is measured on the graduated piston stem. Rubber balloons should be ordered separately.
