An innovative technique used on box beam bridge structures included in the rapid bridge replacement project is the application of a polyester polymer concrete ppc overlay.
Polyester polymer concrete overlay.
Rapid return of traffic.
Overlay of the existing pavement which had no diamond grinding to remove rutting.
Lessons from past experience.
Polyester polymer concrete can achieve rapid 2 hour cure after placement even in cold humid conditions below 40 f.
1 as a 1 inch thick inlay of the entire lane that was diamond ground to remove.
With millions of square feet of bridge deck polyester concrete overlays placed ppc 1121 has a successful history dating back to the first overlays placed in 1983.
Polymer concrete bridge deck overlay systems that have been used include mixtures containing epoxy coal tar modified epoxy polyester methyl methacrylate and polyurethanes.
Fastrac ce700 hpc is a three component hybrid polymer concrete system containing engineered polymer resins and specially selected aggregates.
The overlay material is designed to protect bridge decks from the infiltration of deicing salts and reduce long term maintenance costs.
