Paint residue generated by bridge maintenance painting commonly contains lead requiring the residue to be disposed of as a hazardous waste. Several alternatives are being investigated in this study, chemical stabilization and recycling as options for the Kentucky Transportation Cabinet (KYTC) to consider in addressing the waste stream generated by bridge maintenance painting operations.

In the initial portion of this study, four chemical stabilization materials were identified as candidates for xperimental/demonstration projects entailing maintenance painting. A recycling option was also provided. An experimental bridge painting project was let by KYTC to investigate the use of two chemical stabilizers and the recycling option. The results of that effort are discussed including chemical analyses, progress of work, and resulting costs. Recommendations are provided for additional testing of chemical stabilizers.
