Theoretical Maximum Specific Gravity

A loose sample of either laboratory or plant produced HMA is weighed while dry (to determine its dry mass) and then a short procedure is used to determine the sample's volume The theoretical maximum specific gravity is then the sample's mass divided by its volume (Va) in laboratory compacted mixtures and in-place density in the field Get price

Compaction of Soil

Compaction of soil is an important process as it helps it of achieve certain physical properties necessary for its proper behaviour under loading for example proper compaction of an earthen dam or a highway Embankment reduces the chances of its settlement increases the shear strength of the soil due to its increased density and reduces the permeability of the soil Get price
