Because of numerous freezing and thawing cycles happening during the year in the state of Ohio, pavement partial-depth patching has become a common maintenance activity in this state. The Ohio Department of Transportation (ODOT) has a need for durable, more permanent high performing pavement and bridge deck materials that allow for a faster repair and for user safety. However, new or proprietary products are difficult to specify unless incorporated into a construction project for research purposes or procurement of the product complies with the ODOT's direct purchasing requirements.This research project was conducted in three main phases, literature review and selecting the proper materials, field patching and inspection of the materials, and laboratory testing of the materials to compare the results to the field inspections. All these phases were conducted in order to specify for use in future ODOT construction, based on the field and laboratory performances of the products. As the last phase of this research project, this thesis investigates the properties and performance of the selected products used for partial-depth repair of concrete pavement in a laboratory. The materials were tested for freeze-thaw, modulus of elasticity, strength, shrinkage, ultrasonic pulse velocity, mass change, and scaling damage to quantify their characteristics relative to those products known to work well. The objective of this study was to document the investigation of the lab testing of selected repair materials for partial-depth repair. The investigation determined the acceptable laboratory tests for comparative analysis of existing repair materials. Eventually, the investigated materials were ranked based on their overall performance considering economic aspect and their laboratory and field performances
