     · During the construction of earth structures, it is essential that the fill material be uniformly compacted to meet the compaction specifiion requirements. Current compaction verifiion methods require field inspectors to perform in situ quality assurance/quality control (QA/QC) "spot tests" at a finite number of loions within the compacted area. As a result, a large percentage of ...

     · 3. By comparing the loaded density to the insitu or the compacted, you will then be able to calculate your "compaction" factor for the materials. Measurement can then take place at your with little worry. Keep in mind that the geotech will have to take samples as the material could change somewhat and pose a slight risk for claim.
