FIELD STUDIES ON THE PULVERIZATION OF BLACK COTTON SOIL FOR THE CONSTRUCTION OF STABILIZED SOIL ROAD BASES

STABILIZATION OF BLACK COTTON SOIL WITH LIME HAS BEEN FOUND EFFECTIVE IN IMPROVING THE ENGINEERING PROPERTIES OF THE SOIL. CONSEQUENTLY, THIS HAS LED TO THE INCREASING USE OF LIME-STABILIZED BLACK COTTON SOIL IN SUBBASES OR BASES OF ROAD PAVEMENT. A PROPERLY PULVERIZED SOIL IS, HOWEVER, A PREREQUISITE FOR SUCCESSFUL STABILIZATION OF SOIL. THIS PAPER DESCRIBES A NUMBER OF METHODS THAT HAVE BEEN TRIED IN THE FIELD TO ACHIEVE AN ECONOMICAL AND EFFECTIVE PULVERIZATION METHOD. IT HAS BEEN SHOWN THAT AN ACCEPTABLE DEGREE OF PULVERIZATION CAN BE ATTAINED WHEN THE SOIL IS HANDLED MECHANICALLY AT A PARTICULAR MOISTURE RANGE BY USING AGRICULTURAL MACHINERY. /AUTHOR/
