Concrete-Polymer Materials for Highway Applications
The use of concrete-polymer materials for highway applications has been studied with the objectives of providing durable materials that would reduce maintenance in highway structures. Several significant developments resulted from this reseach. Partial-depth polymer impregnation was developed for improving durability of bridge decks. The process includes drying the concrete, cooling the surface, applying a low viscosity monomer solution to a sand cover, and permitting it to soak into the concrete, and applying heat to polymerize the monomer in the concrete to a depth of 0.5 in. (1.3 cm) or more. Post-tensioned polymer-impregnated beams were made and tested to determine the structural behavior. Beams with an I-shaped cross-section and a span of 8 ft (2.7 m) were fully impregnated with a monomer solution. High strength wire tendons were post-tensioned and the beams were tested to determine the flexural and shear behavior. Significant increases in strength and stiffness were observed. Time-dependent deflections were reduced by an order of magnitude. Polymer concrete was developed for repairing bridge decks.
