INFLUENCE OF COARSE FRACTION ON COMPACTION CHARACTERISTICS AND CBR STRENGTH OF A FINE GRAINED SOIL

This paper aims to study the influence of coarse fraction on compaction characteristics and CBR strength of a fine grained soil. The replacement levels of coarse fraction in the soil have been kept at 5%, 10%, 15%, 20%, 30%, 40%, 50% and 100%. The investigation is carried out by conducting the vario...

Zusammenfassung:This paper aims to study the influence of coarse fraction on compaction characteristics and CBR strength of a fine grained soil. The replacement levels of coarse fraction in the soil have been kept at 5%, 10%, 15%, 20%, 30%, 40%, 50% and 100%. The investigation is carried out by conducting the various tests to determine optimum moisture content (OMC), maximum dry density (MDD) and California bearing ratio (CBR) on these mixtures. From the results, it is observed that OMC has been gradually decreased with the increased percentage of coarse fraction till some level and thereafter OMC has increased. Whereas, MDD has been increased with the increased percentage of coarse fraction till some level and thereafter this value has decreased. It is noted that the CBR value of 2.5 mm penetration is greater than or equal to 5 mm penetration for all the mixes.
