• Abstract:
  Ensuring that sufficient water is available in hydrating concrete is of great importance to produce durable ; concrete and achieve both short- and long-term performance of concrete pavement. Excessive early-age ; evaporation from the surface of concrete pavement often results in high porosity delaminated and low ; strength concrete. Application of curing compounds in concrete paving is widely used to minimize ; evaporation. However, the Texas Department of Transportation (TxDOT) standard specifications for ; pavement construction (Item 526) only defines the use of the membrane curing in terms of key ; characteristics such as percent solids, density, viscosity, color, and the application rate, but does not specify ; curing performance or limits on the rate of evaporation. ; This research utilized several techniques to evaluate curing effectiveness from both a moisture retention and ; physical properties standpoint, to develop a laboratory-based curing evaluation protocol that has application ; to the field. ; A series of tests were carried out to identify factors controlling curing quality under field conditions.
