2268 - Use of a Novel Controlled Release Surface Curing Agent for Bridge Decks

The durability of concrete bridge decks is critical to the satisfactory long term performance of the Oklahoma highway infrastructure system. It is currently required in Oklahoma to place wet burlap or blankets within 10 minutes of strike off of the concrete surface. The job of these materials is to minimize moisture loss, promote hydration, reduce permeability, increase strength gain, and minimize cracking. Current wet curing techniques are labor intensive, logistically challenging, and quite costly. Also the placement of these materials too early can cause unwanted deformations or damage in the surface of the concrete that may nullify any benefits from the curing. The objective of the project is to use a novel curing technique that can be rapidly applied to the surface of the fresh concrete and not cause deformations in the concrete surface. This material should show equal or better curing performance then typical wet curing methods and be sustainable and safe for the environment. The specific objectives for this project include: (1) Develop a field application method for the novel curing material; (2) Develop specifications for the quality control and usage of the novel curing material; an (3) Work with contractors in Oklahoma to implement this technology in the field and evaluate the effectiveness
