Petrographically Quantifying the Damage to Field and Lab-cast Mortars Subject to Freeze-thaw Cycles and Deicer Applications Open
Although calcium oxychloride (Ca-Oxy) is known to damage cementitious materials exposed to calcium chloride (CaCl 2 ) deicers, there is little direct observation of Ca-Oxy in the field due to its instability. This paper uses optical micros…

Implementing Rapid Durability Measure for Concrete Using Resistivity and Formation Factor Open
The durability of in-place concrete is a high priority issue for concrete pavements and bridges. Several studies have been conducted by INDOT to use electrical resistivity as a measure of fluid transport properties. Resistivity is dependen…

Synthesis: Accelerating Implementation of Research Findings to Reduce Potential Concrete Pavement Joint Deterioration Open
Distress has recently been observed in the joints of some concrete pavements, primarily in the wet-freeze states. This distress often begins in longitudinal joints, followed by transverse joints and results in the significant loss of mater…
