Abstract:

High early-strength materials are widely used for rapid concrete patching projects to limit road closure time and traffic obstruction. This research investigated the field performance of multiple high early-strength materials used in maintenance projects across Nebraska. Data from high early-strength products included in the state’s approved product list were collected and compared to field performance. In addition, a survey was prepared and distributed to the surrounding states to understand standard practices related to appropriate specifications of these materials that can be later used to develop specifications for the utilization of high early strength materials in Nebraska based on experimental and filed evaluation data. Field inspections of multiple repair projects across Nebraska were performed. The field data were analyzed and plotted against the experimental data of each high early-strength material to investigate the potential of utilizing experimental data to predict the long-term performance of high early-strength materials. Based on the results, early strength and setting time showed a potential correlation with the field data represented by the normalized crack length.
