Field Trial Assessment and Performance Prediction of Containerized Cold Patching Mixtures

Cold patching asphalt mixtures constitute an essential element for the maintenance and rehabilitation of pavement infrastructure. Although this maintenance technique is both expensive and time consuming, it can minimize further damage and costly future repairs as well as increase user and vehicle safety. As a result, cold patching mixture performance is critical. Unfortunately, no method has been identified in establishing or modeling the workability or performance of cold patching mixtures. This paper evaluates the workability and performance of containerized cold patching mixtures that were installed as part of a field trial by Texas Department of Transportation. Furthermore, data collected in this field trial was analyzed and used to develop linear regression models that characterize the workability and performance of the containerized cold patching mixtures and identify statistically significant differences. These models serve as an indication toll for materials that showed better workability and performed better in specific areas. Using results from both models, the best containerized patching mixture was identified. In conjunction with other information, such as availability, material cost, time required for patching, and hourly maintenance personnel cost to install the patches, model results will identify the most cost effective cold patching mixture.
