Cement-treated subbases for concrete pavements
Contribution of cement-treated subbases to load-carrying capacity of concrete pavements was investigated; slab responses to loads were compared with theoretical behavior of concrete slabs on clay subgrades; cement-treated subbases improved load transfer across joints; pavements with grout bond resisted deflection as effectively as unbonded designs with added 1/2 to 1 in. of concrete thickness; emulsion produced erratic bond; these pavements on average were only slightly stiffer than those without bond; upward curl and deflections at corners of curled slabs were less for designs with grout bond than for other treatments; fatigue studies indicated excellent endurance for all pavements tested.
