COMPARATIVE STUDY OF SOIL-CEMENT MIX DESIGN METHODS

Abstract

Boil stabilization has new became an integral part of highway construction. The uset%iinsss of strong base course is now an adaowlsdged fact. Among all the other methods of stabilization soil-ceaent stabilization is the most casrtsn method bec nse of its many advantages, It not only gives a strong base course but also helps is reduclag the moisture variations in the pavement thus Increasing its life. AU most an types of soils can very well be stabilized with assent, But fineness and mineralogical conpositicn of the soil affect the soil cement nix very much. Soils having very large quantities of fine grain particles (sisU.r than 0.00a.) are very difficult to be stabiiaed with comeut alone, It is bserved that soils having clay Content ( smaller than 4.00s) sore then 38,E and liquid limit sore than 50% with Plastic Index wore than 2* are very diffimlt stabilise economically with cesent, Thus it is essential to know the exact behaviour and mechanism of soil cement stabilisation. By knowing these factors a very exact and rational method of soil cement *ix design can be evolved..
