Effect of Alternative Materials on Properties of Expansive Soil for Construction of Road Subgrade by using Cocnut Husk Ash
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2020, Vol 4, Issue 6
Abstract
Pavement engineers have long recognized the long term benefits of improving the strength and durability of pavement soil by mixing in a cementitious binder during reconstruction or new construction. In lieu of these, this research was carried out to study the effects of coconut waste ash CWA on lime stabilized lateritic soil for road construction. Natural lateritic soil was collected from a borrow pit nearer location Preliminary tests such as natural moisture content, specific gravity, particle size distribution and Atterberg limits were carried out on the soil for classification and identification purposes according to BS 1377 part 2 1990 . Strength tests such as compaction, California bearing ratio and unconfined bearing ratio were also carried out on the natural lateritic soil and stabilized soil according to BS 1924 1990 . The soil sample was mixed with lime in the proportions of 2, 4, 6, 8 and 10 , and were each subjected to Atterberg limits tests and strengths to determine the optimum quantity of lime for stabilizing soil. The plastic index varied from 13.93 – 9.33 and 23.64 – 14.46 for lime stabilized soils with optimum values obtained at 8 and 6 respectively. Plastic index decreased as the percentages of lime and CWA increased for CWA of ratio 1 1, 3 2 and 2 3 i.e. PI varied from 8.63 to 11.91 . Notable improvements were also observed in the MDD, UCS, OMC and CBR values of stabilized soil therefore coconut waste ash can be used to stabilize lateritic soil. Hence, the use coconut waste ash CWA should be encouraged in the construction industry to reduce the cost Akkim Sridhar Reddy | P.
