We previously presented episodes dealing with the (standard) proctor, consisting of two episodes
All specifications for backfilling work state that the backfill achieves a success rate of not less than (for example) 95% of the maximum dry density according to the Proctor test. Do you know what the Proctor test is??
Let's learn together how to do the modified proctor test in the lab.
The goal of the proctor test
The objective of the Proctor test is to: Determine the maximum dry density and the optimum moisture content with which the field density will be compared, as well as determining the energy to which the soil is exposed to compaction in the laboratory to represent it on the ground using various compacting tools and equipment
The two methods used to test for compaction are:
Standard Proctor Test
Modified Proctor Test
