Polymer-Impregnated Concrete for Highway Applications
Polymer-impregnated surface treatments have been developed to improve durability of bridge decks. Surface treatment evaluations were performed to determine the effectiveness of the treatments. Freeze-thaw tests indicated that field treated slabs were more durable than non-air-entrained control slabs. Air-entrained control slabs were quite durable but were less resistant to scaling than treated slabs. Treated slabs resulted in improved water tightness in all cases. After undergoing freeze-thaw tests, many impregnated slabs maintained a relatively watertight concrete surface. Wear track tests and skid resistance tests were done. Tests on surface-treated reinforced beams indicated a 22% higher strength than for untreated beams. Under cyclic loading, no spalling of the surface has been observed to date. Unreinforced beams broken in flexure have been repaired successfully with monomer systems that yield approximately the original flexural strength. Significant savings are likely if the surface treatment procedures are implemented.
