Abstract:

Concrete freeze-thaw durability is prominently linked to the air void system within the concrete. ; Concrete pavements in Kansas undergo repetitive freeze-thaw cycles. Total air content measurements ; currently used on fresh concrete do not provide any indication of the air void size distribution. The Super Air ; Meter (SAM) addresses this issue by providing the air content and an additional number, the SAM number, ; which is claimed by the manufacturer to correlate to the concrete hardened air void spacing factor. In order to ; determine the variability and the frequency of testing needed for the SAM test, 16 sites across Kansas were ; investigated. The SAM test was performed at least once for every hour of paving. This study found that the ; SAM number has a 154 percent higher coefficient of variation per site than the total air content. It was also ; seen that there is a correlation between the air content and the SAM number. It is recommended that the ; Kansas Department of Transportation (KDOT) perform the SAM test at least four times per site per day.
