• Abstract:
  Non-durable coarse aggregate in concrete pavement can break down under ; repeated freeze-thaw cycles. Application of rock salt may increase the severity of ; exposure conditions because of trace compounds, such as calcium sulfate, in rock ; salt. Concrete and saw-cut limestone specimens were also subjected to wet-dry ; cycles in varying salt solutions to examine the influence of trace compounds in ; rock salt. Subsequently, limestone aggregate in concrete was subjected to freezethaw ; cycling in two methods: salt-treating the aggregate before batching concrete, ; and half-immersing concrete specimens in rock salt solution during freeze-thaw ; cycling.
