JMT - 616
MINIATURE FIELD PERMEMETER
For determining the permeability characteristics of soils, solidified soils and rock cores, high- pressure permeability studies can be carried out. The complete outfit comprises: - Mould 50mm diameter x 100mm high and collar, Top Plate, Base plate with recess for porous stone and porous stone, Indicator pipette, 6mm x 300mm x 300mm long. Reservoir tank fitted with 7kg/cm gauge, valves, flow control regulator and foot pump
When Compaction of soil in the field is done using rolling machines, it is important to know O.M.C.and M.D.D. values. Standard Compaction test is used to determine in laboratory Optimum Moisture Contents (O.M.C.) and Maximum Dry Density (M.D.D.) of soils, which represents field samples.
Compacted soils have increasing use in embankment of dams, highways, railways etc. in recent years in order to meet current heavy traffic on runways and highways, heavy duty field compacting equipment has come into use and in view of reproducing greater densities, heavy compaction tests using heavy compaction apparatus have been developed.
