Several overlay test sections were placed on two bridge decks and a section of a concrete approach pavement in Fort Worth, Texas, about five years ago. Different monomers, primers, mix designs, and construction methods were used. The same materials were investigated extensively in the laboratory. The test sections were open to regular traffic and tested several times over the past five years. The results and conclusions of this experimental program are presented here.
