Tests of concrete pavement slabs on cement-treated subbases
Tests to determine deflection, strain and pressure response to static loads are described; concrete thickness varied from 3 to 8 in. and subbase thickness from 3 to 9 in.; subbase surface treatments were cement-sand grout to produce bond; polyethylene film to prevent bond, and in one instance, asphalt emulsion; loads were applied at interiors, edges and joints; it was shown that bonded interlayers increased ability to carry load as much as additional 1/2 to 1 in. of concrete; experimental deflections at interiors and edges were in good agreement with those computed by Wester-gaard formulas when bearing value of cement-treated subbase was measured by 30-in. plate.
