USAGE OF THE VIBRATION COMPACTION MOLDING MACHINE
For non-viscous free the determination of the maximum dry density of soil and water conservation, the curve of the compaction test method type test curve is no significant peak or peak, which suggests that the law of this kind of soil is not the most appropriate test method. And the compaction method to determine the maximum dry density are often lower than vibration compaction test results. The British standard BS1377, Sweden SS027109 rules for high permeable soil using the surface vibration compaction meter method. China's ministry of communications industry standard "regulations of the road test" (JTGE40-2007) combined with the experiment research of the ministry of communications highway research institute, new increased the method and the method of vibration table as a giant grain of cohesionless coarse grained soil basic test method for the determination of maximum dry density of soil. Surface vibrator method similar to the working condition of vibration compaction, easy to operate, sample in real-time vibration pressure does not produce separation phenomenon. Complex vibration table method, sample separation phenomenon in the vibration compaction process, therefore, recommended priority JTG40-2007 using the surface vibration compaction meter method, and this method can also be used for three axis of coarse grained soil test, penetration test, experiment and basic materials such as concrete material parts work.
