FIELD DRY DENSITY BY SAND REPLACEMENT METHOD

In this video we will learn with practical how to find out the FDD of subgrade layer of pavement at site.In-situ density is widely used to control the field compaction of earthworks and pavement layers. The sand replacement method is the most widely used in-situ density test. Although the test takes slightly longer to perform than some other in-situ density tests, the test may be carried out on most type of materials
