Abstract

The state of Ohio is in a region that commonly experiences drastic changes in weather. States with similar climates are susceptible to pavement cracking and failures due to the frequent or extreme freeze-thaw cycles. Freeze-thaw cycles, paired with de-icing chemicals that are frequently placed on roadways during the winter months will most likely lead to pavement cracks and failure. Ohio Department of Transportation (ODOT) routinely repairs and replaces sections of concrete roadways and bridge decks. Therefore, ODOT is seeking durable, cost-effective materials to repair smaller pavement failures.

The purpose of this study is to determine which high performance repair materials would be suitable for implementation in ODOT’s construction practices. This includes selecting a variety of high performance repair materials, installing said materials in the field, conducting laboratory testing, and determining which materials are the most efficient and cost-effective. The activities that occurred during this study consist of visual inspections of previously installed high performance repair material patches, the nondestructive testing of each patch, and the installation of two types of selected repair materials. These repair materials are MG Krete and RepCon 928. The results of this study will help determine which of these materials would be optimal to implement in areas with extreme climates.
