• Description:
  Field inspections and a recent study report ("Cracking in Bridge Decks: Causes and Mitigation”, CDOT Report 99-8) showed that the cracking problem of bridge decks in Colorado has not been completely solved, and therefore, there is a pressing need for further improvement of the concrete mix designs currently used in Colorado for concrete bridge decks. Four different tests were selected for characterizing the mechanical properties and durability properties of concrete. Compressive strength tests at 3 days, 7 days, 28 days, and 56 days; rapid chloride permeability tests (AASHTO T277) at 28 days and 56 days; and crack resistance tests (or ring tests, AASHTO PP34-98) were performed for all concrete specimens. Drying shrinkage tests were performed on selected concrete specimens.
