Polyester Polymer Concrete Overlay

Lessons from past experience.

Polyester polymer concrete overlay.

Fastrac ce700 hpc is a three component hybrid polymer concrete system containing engineered polymer resins and specially selected aggregates. 1 as a 1 inch thick inlay of the entire lane that was diamond ground to remove. Polyester polymer concrete overlay. Polymer concrete bridge deck overlay systems that have been used include mixtures containing epoxy coal tar modified epoxy polyester methyl methacrylate and polyurethanes.

The overlay material is designed to protect bridge decks from the infiltration of deicing salts and reduce long term maintenance costs. The ppc was applied in three methods. With over 200 bridges completed with polyester concrete throughout the united states myers and sons construction is the preeminent contractor when it comes to placing polyester polymer concrete overlay s. Polyester polymer concrete ppc was used in a trial application as a possible repair strategy on a section of concrete pavement that suffered from extensive studded tire wear.

When properly mixed the reacted chemistry produces a durable polymer concrete composite designed for bridge deck overlays patching and resurfacing applications. The test sections will be monitored for a minimum of five years to determine the performance of the ppc with particular emphasis on its ability to resist studded tire wear. 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. Polyester polymer concrete can achieve rapid 2 hour cure after placement even in cold humid conditions below 40 f.

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. Overlay of the existing pavement which had no diamond grinding to remove rutting. Polyester polymer concrete overlay.
