• Abstract:
  Concrete pavements represent a large portion of the transportation ; infrastructure. While the vast majority of concrete pavements ; provide excellent long-term performance, a portion of these ; pavements have recently shown premature joint deterioration. ; Substantial interest has developed in understanding why premature ; joint deterioration is being observed in jointed portland ; cement concrete pavements (PCCP). While some have attributed ; this damage to insufficient air void systems, poor mixture design, ; or chemical reaction between the salt and the paste, it is the ; hypothesis of this work that a component of this damage can also ; be attributed to fluid absorption at the joints. ; This report begins by discussing the importance of the level of ; concrete saturation on freeze-thaw damage. It was determined ; that damage can occur in samples having a degree of saturation ; higher than some critical value (approximately 86%) after even ; one freezing cycle. When deicing salts are used, the freezing ; temperature is depressed; however, additional damage is observed ; as compared to just water. Additional damage appears to occur on ; thawing for systems with higher salt concentrations, presumably ; due to the phase change in the hydrohalite.
