Field Compaction Methods for Soils PDHonlineWhat is the significance of ten percent fines value in

The proctor compaction test is a test that compacts the soil material at various moisture contents There are two proctor tests that defined by the American Association of Highway Officials and American Standard Testing Material The Standard Proctor test ASTM D 698 AASHTO T 99 and the Modified Proctor test ASTM D and AASHTO T 180 The use of the Standard Proctor or Modified Proctor The test aims at looking for the forces required to produce 10 of fine values ie weight of fines aggregates/weight of all aggregates = 10 This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value

Soil Mechanics kauAggregate Crushing Value Ten Percent Fines

Soil Mechanics Soil is the most misunderstood term in the field The problem arises in the reasons for which different groups or professions study soils Soil scientists are interested in soils as a medium for plant growth So soil scientists focus on the organic rich part of the soils horizon and refer to the sediments below the weathered zone as parent material Classification is based on Aggregate Crushing Value Ten Percent Fines provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load
