Field Density Test The sand cone method is used for field density test in highway construction. In the field, the dry density test is performed to check the compaction of layers. Compaction is most beneficial for the preparation of sub base grade and different pavement layers and in the production of embankment in order to increase the steadiness and to lower settlement. In field compaction, the compacting moisture content is first controlled at ideal moisture content and the adequacy of rolling […]
