Although it has no similarity to any type of field compaction method，the Proctor compaction test is by far the most popular laboratory testing method

and it is widely accepted that the proctor compaction test is ineffective for cohesionless soils. Vibration compaction test for cohesionless soils needs to be improved for the practical applications. Due to the application of much heavier earth moving and vibration roller compaction equipment

soil densities compacted in the field are reaching levels that are not attainable in the laboratory. This paper introduces the test results of the gyratory test procedure conducted with Servopac gyratory compactor with 200kPa vertical pressure

1.25 degree gyration angle

90 gyrations

and 20 gyrations per minute，and the test results show considerable promise to be the construction specification for the quality control of field compaction for granular soils.
