An experimental study on embankment and subgrade soil is conducted to study the principles of soil compaction to establish a relationship between dry density and moisture content. A conventional test method for subgrade and embankment construction covers less compaction (about 1%). The intelligent compaction technology offers a method to measure 100% of compaction. The increased compaction zone leads to decreased maintenance costs and an extended service life. In this study the effectiveness of rollers, their specification and degree of compaction is observed. In the present study, project site at Honnali Taluk Basavapattan village( latitude 14.244 and longitude 75.677) is selected. A soil sample from site is brought and tests are conducted to know their index properties. The soil is classified according to Bureau of Indian Standard soil classification. A prototype smooth drum vibratory SD 110 roller is utilized that allowed for simultaneous real time machine driven power measurements, which permitted independent and simultaneous evaluation of the degree of compaction of soil. Total station equipment is used to monitor the thickness of each layer after compaction. In the field core cutter and rapid moisture meter instruments are used to determine the field in-situ density and moisture content. The result revealed some correlation exists between MDD and OMC. The number of rolling versus machine driven power. The degree of compaction was 100% with 8 number of roller passing.
