5 Important Types Of Rollers Used In Soil Compaction

06.10.2021 · They are very efficient in crushing oversized material in gravels. However, they are not ideal for some categories of soils including uniform, silty clays and clayey soils as they will not perform well. So they work perfectly in subgrade and sub-base road projects. Not like other rollers, a grid roller compactor can easily adapt to the soil’s bearing capacity and extricate itself.

Head lift can be calculated with the PSI. Take the PSI of the pump and multiply it by 2.31. For example: If a pump has a PSI of 65, multiply it by 2.3 and that equals a 150 foot head: 65 x 2.3 = 150. PSI can be calculated with head lift. Take the head lift number and divide by 2.31. For example: If a pump has a head lift of 150 this can be divided by 2.31 which equals 65 PSI.
