Evaluation of Roadware 10-Minute Concrete Mender for PCC Bridge Deck Crack Sealing

To prevent corrosion of reinforcing steel, Wisconsin Department of Transportation (WisDOT) routinely seals cracks in bridge decks as preventive maintenance. Current methods used to seal cracks are time consuming and costly. This has resulted in the search for other maintenance solutions. Several different products have been used to address this issue, but the majority of products currently used are labor intensive and require a lot of time to cure. In this experimental study, a product called the Roadware 10-Minute Concrete Mender was evaluated. According to the manufacturer, the 10-Minute Mender has extremely low viscosity for deep penetration into concrete and cures in a wide climate range (from 100 deg F to subzero temperatures). The product cures in just ten minutes and requires only one or two laborers to do the work. Based on the feedback from the WisDOT districts that are involved in this study, the 10-Minute Mender has performed very well. The high cost of the 10-Minute Mender was offset by the ease of application and short time required to cure. A fairly new product called TK-9030, similar to the 10-Minute Mender in packaging, application, and performance, is also available on the market. This product was briefly included in this research study. TK-9030 appears to perform as well as the Roadware 10-Minute Concrete Mender, at less than half the cost.
