The Waco Ponding Project
This report presents results of field studies conducted between 1957 and 1972 which were concerned with the effectiveness of ponding and lime stabilization of clay subgrade in minimizing volume change beneath portland cement concrete pavements. Potential Vertical Rise (PVR) was calculated to identify sections in need of ponding and the relationship of PVR to roughness and heaving of pavement is presented. The thickness of asphaltic concrete overlay required for pavement over untreated subgrade is compared to that required for concrete pavement placed over lime-stabilized subgrade, some of which was ponded. Although a study of underdrains was not intended to become a part of Research Report 118-7, it became noticeable that the result of connection of perforated underdrains to ditch drop inlets was to increase heaving and overlay repair thicknesses. A method for determination of 'desired' moisture content is presented in the report and it correlates fairly well with moisture contents obtained from below pavement after a period of several years had elapsed.
