Balloon Density Apparatus
Product Code : EL-STLE-10387
Quick Answer: The Balloon Density Apparatus is used to determine the in-situ density of compacted or firmly bonded soils using a rubber balloon method, in which a graduated cylinder and rubber balloon measure the volume of a test hole. It weighs approximately 6 kg, conforms to ASTM D2167 and AASHTO T205 standards, and is not suitable for very soft soils that deform under slight pressure or where the hole volume cannot be kept constant.
