Detennine CUlTent KYTC practice for applYing deicing salts to bridge decks including monitoring deicing materials. methods of deicing application (i.e. wet/dry). application frequency and application rates statewide. Identi~ candidate bridges to monitor aJillual deicing salt application. chloride penetration into bridge decks, resultant deck deterioration (spalling andlor corrosion I. Identi~ sealaJlts, densifiers and inJ,ibitors used nationwide to protect reinforced conCrete bridge decks from chloride induced corrosion. Identi~ deicing salt substitutes. inhibitors and extenders used to limit deicing salt induced cOlTosion. Survey state SHAs to identi~ treatments'practices that minimize bridge deck exposure to deicing salts or to associated damage. Conduct laboratory salt-ponding tests of yarious sealants. densiliers and inhibitors along with salt substitutes. salt inhibitors and extenders to detennine which ones are effective for addressinglJiIniting corrosion of bridge deck reinforcing steel. Conduct laboratory tests of treatments to limit deicing salt use in the experimental projects. Monitor experimental bridge deck treatments to eyaluate application procedures for sealants. densifiers and inhibitors found to be effective in laboratory tests. Apply effective salt substitutes, salt inltibitors or extenders on selected bridges. 'I1easure deicing salt impacts on corrosion. ;,1onitor other experimental deck treatments/practices detel1nined to be effective in limiting long-tenn exposure/concrete penetration by deicing salts Prm-jde KYTC with recommendations implementing bridge preservation actions including the application of sealers, densifiers andior inhibitors to bridge decks. Tbat will include guidelines for using those treatments on specific categories of bridges (detennined in the study). Additional recommendations will be proyided for the use of any effective salt substitutes, inhibitors and extenders. Any related treatments/practices found to be effective will also be recommended.
