ABSTRACT:
A novel displacement instrument that can be used to measure the density or modulus of an aggregate pier upon which a multistory building or parking garage can be built. The aggregate piers are often 35 feet or deeper. These aggravate piers are constructed by adding lifts of approximately 12 to 18 inches of aggregate at a time and tamping it into the pier forming hole. Each lift of aggregate is being tamped or struck by a force of approximately 15,000 psi or greater. The displacement instrument allows aggregate piers to be constructed having a density or modulus that is consistent from the bottom of the hole to the top of the hole. The displacement instrument would be mounted on the side plate of a hydraulic breaker that is mounted on the end of a boom of a crane. The displacement instrument need not be permanently installed on the side of the hydraulic breaker and it is freely removed and installed on another crane.
