STRUCTURAL EVALUATION OF LIME STABILIZED SUBGRADES

THE ADDITION OF LIME TO A HIGHLY PLASTIC CLAY SUBGRADE HAS BEEN KNOWN TO INCREASE THE LOAD CARRYING CAPACITY OF THE SUBGRADE AND THEREBY REDUCE THE DESIGN REQUIRED THICKNESS OF GRANULAR BASE COURSE. SINCE THE LATE 1950'S THE MANITOBA HIGHWAYS DEPARTMENT HAS LIME STABILIZED SEVERAL SUBGRADES EACH OF WHICH HAVE INCORPORATED SEVERAL DESIGN VARIABLES, SUCH AS PERCENTAGE OF LIME AND DEPTH OF TREATMENT. A BRIEF DESCRIPTION IS GIVEN OF THREE LIME STABILIZATION PROJECTS. BENKLEMAN BEAM AND PLATE BEARING TEST RESULTS ARE USED IN AN ATTEMPT TO DETERMINE A DEPTH EQUIVALENCY OF LIME STABILIZED SUBGRADE TO GRANULAR BASE COURSE. /CGRA/
