The report describes an investigation to determine the effectiveness of lime for treating expansive soils under portland cement concrete pavements to minimize slab distortion or curl caused by moisture differentials in the clay basement soil. Several short experimental sections were constructed by lime treating the top 6 inches of the expansive clay soil and reducing the cover requirements. The moisture content at various elevations in and below the pavement section was measured periodically by nuclear probes which were installed during construction. The extent of distortion or curl was measured by the California truck-mounted profilograph and by profiles with an engineer's level over areas exhibiting high roughness index values. It was concluded that lime treatment is a feasible method of minimizing portland cement concrete pavement curl resulting from expansive subgrade soils. (Author)
