The usual weights of these machines vary from 100 kg to 2 tonne with plate areas between 016 m 2 and 16 m 2.

. Vibrating plate compactors are used for compaction of coarse soils with 4 to 8 fines. Levelling is the most widely used method of obtaining the elevations of ground points relative to a reference datum and is usually carried out as a separate procedure to those used in fixing planimetric position. In this article we will deal with the next important method rule ie.

Levelling is a process of determining the height of one level relative to another. It is used in surveying to establish the elevation of a point relative to a datum or to establish a point at a given elevation relative to a datum.
