摘要: AbstractExtensive amounts of natural quarry aggregates are currently being used in road and pavement applications. The use construction demolition (C&D) materials such as recycled concrete aggregate (RCA), crushed brick (CB), reclaimed asphalt (RAP) an alternative to has generated interest recent years, particularly a base or subbase material. However, the resilient moduli responses performance these C&D reinforced with geogrids under repeated loads have yet be established. This research investigates (MR) permanent deformation characteristics biaxial triaxial load (RLT) equipment. effects varying deviatoric stress on modulus unreinforced geogrid-reinforced were also investigated. Regression analyses test results performed using two- three-parameter mode...
