Compaction Control Field Testing: • During the construction of the project, a control must be in place to measure whether or not the compaction requirements have been met. • That control is density testing. ... • Sandreplacement (sand cone) method,
The amount of sand eligible for replacement is limited to the amount lost as a result of the incident. FEMA uses the pre and poststorm profiles of the beach to determine the eligible volume of sand for replacement. If prestorm profiles are not available, FEMA estimates the amount of sand lost using design documents and renourishment history.
Sand Replacement Method is also known as Sand Cone Method. The apparatus used in this field density test consists of a sand pouring cylinder, with pouring cone at its base. There is a shutter between the cylinder and the cone.
