Brief Description

Description :

Wide usage for quality control of soil fills in different areas viz. Roads, Dams, Railways and other applications. The method also create week spots in the compacted fill affecting the durability of roads. But with the help of developed equipment the field dry density shall be estimated without destructing the compacted soil and this method is faster than the conventional method.
