After compaction of soil on project sites like roads, embankments and foundations it is important to verify whether the soil has achieved the required compaction or not through Field Density Test (FDT). This test ensures that the field compaction matches the design specifications determined from the laboratory Proctor Test.
Field Density Test is a geotechnical procedure used to determine the on ground density of soil at the site. It is mainly conducted after compaction activities to verify the soil density meets the required percentage of the Maximum Dry Density (MDD) obtained from the Proctor Compaction Test. Typically the goal is to achieve 95% to 98% of the lab MDD in the field.
Results
Field Density Test is crucial to ensure that the soil has been compacted properly on site according to engineering standards. It acts as a quality control measure to ensure that the soil meets the design
Proper field compaction testing protects the projects from future failures and ensures safe & durable construction by meeting required compaction values.
