An experimental investigation was conducted to study creep and shrinkage characteristics of latex-modified mortar (LMM) and concrete (LMC) used for bridge deck overlays. The test program included eight prisms of latex-modified mortar and eleven prisms of latex-modified concrete prepared to be tested for almost 8 months. Empirical equations for predicting shrinkage strains of LMM and LMC show that shrinkage of LMM is almost double that of LMC and air-entrained normal weight concrete (AEC). Empirical equations developed for predicting creep of LMM give values of the same order of magnitude as those of AEC.
