Abstract

This paper presents a work carried out for improving the strength characteristics of the sub grade
soil. Most of the areas in Dakshina Kannada are found with lithomargic soil. The soil is having
very weak engineering properties which are unsuitable for road construction. The main aim of
this study is to effectively stabilize the soil by using bio enzyme and hypo sludge. Bio enzymes
are extracts from veges and which posses high value of strength when mixed with soil. Also hypo
sludge is a waste from paper industry which is used for soil stabilization since it is having some
part of lime content and effective use of hypo sludge may reduce disposal problem. Hence the
soil is treated with different dosages of bio enzyme as 200ml/3m3, 200ml/2.5m3 and 200ml/2m3
of soil. The hypo sludge is added with 2%, 4% and 6% for the soil. Both the additive treated
soil is conducted with UCC test for 0, 7, 14, 21 and 28 days of curing. Also the CBR tests are
conducted for same dosages under un soaked and soaked conditions. From UCC and CBR results
the optimum contents of additives are obtained. It is noted that the values of Compressive strength
and CBR of treated soil is effectively increased when compared with normal untreated soil.
