A REPETITIVE TRIAXIAL LOADING APPARATUS FOR LARGE DIAMETER SPECIMENS OF GRANULAR MATERIALS
THIS REPORT, SPONSORED BY THE TEXAS HIGHWAY DEPARTMENT IN COOPERATION WITH THE U.S. DEPARTMENT OF COMMERCE, BUREAU OF PUBLIC ROADS, IS CONCERNED WITH THE DESIGN OF NECESSARY EQUIPMENT TO STUDY THE PERFORMANCE OF ROAD MATERIALS UNDER REPEATED LOADING. THE APPARATUS CONSISTS OF A NUMBER OF RELATED SYSTEMS. THE PRIMARY ELEMENT IS A HYDRAULICALLY OPERATED LOADING SYSTEM CAPABLE OF APPLYING REPETITIVE LOADS UP TO 14,000 POUNDS TO LARGE DIAMETER TRIAXIAL COMPRESSION SPECIMENS. RELATED CONTROLS PERMIT SETTING OF THE MAGNITUDE OF THE LOAD, DURATION OF LOAD APPLICATION AND INTERVAL BETWEEN LOAD APPLICATIONS. TEST CONDITIONS ARE MAINTAINED CONSTANT WITH A MINIMUM OF OPERATOR ATTENTION. INSTRUMENTATION IS INCLUDED TO MEASURE THE APPLIED LOAD AND THE DEFORMATION OF THE SPECIMEN. DESIGN CRITERIA AND OPERATING PROCEDURES ARE REPORTED. /RRL/
