Title:

Durability of Brine Applications for Winter Maintenance on Asphalt and PCC Pavements

Abstract:

As part of a larger study of best winter maintenance practices in Ohio, experiments on asphalt concrete (AC) and Portland cement concrete (PCC) pavements were conducted to determine the lifetime of brine residue from pretreatment. The AC pavement was on US Route 23 in Circleville and the PCC pavement on US Route 50 near Athens. On both pavements brine was applied at 20 gallons per lane mile (gplm) (47 liters per lane kilometer (lplkm)), 40 gplm (94 lplkm), and 80 gplm (188 lplkm) using a typical Ohio Department of Transportation (ODOT) brine truck that had been calibrated by the researchers. On US Route 23, a second application at 40 gplm (94 lplkm) at a slower speed was also studied. The amount of salt residue on the road was measured using Boschung SOBO-20 salt measuring devices with rehabilitated electronics. The decay of salt over time on both pavements was found to be consistent with an exponential decay.
