Water required for compaction

 

Bed

Calculate volume of soil = L x B x H.

                                 = 100m x 7m x 200mm

                                    = 140 Cu.M

Now, 

         get M.D.D or O.M.C from proctor test compaction test

if M.D.D 1.90 gm/cc or 1900 kg/meter cube

O.M.C = 11%

Now, get the natural moisture on soil with rapid moisture meter Assume it is 5%.

required moisture = 11% -5% = 6%

 Weight of soil = volume x Density

Calculate weight of Soil = 140 x 1900 = 266000 kg

required water for compaction = 266000 x 6 /100 = 15960 liter water required for compaction.
