OVERLAY THICKNESS DESIGN USING ROLLING WHEEL DEFLECTION RATIO AND CBR THICKNESS FORMULA

The thickness design formula of the California bearing ratio method is used, in conjunction with the common inverse proportionality between pavement life and some power of the surface deflection recoverable under a rolling wheel, to determine the required overlay thickness for an existing flexible pavement. The proposed procedure is compared with other know methods. It has the advantage of including the effects of equivalent single-wheel load and tire inflation pressure as well as the important parameter of subgrade strength, which do not figure in the other methods.
