Project description

The main goal of this proposed research project is to evaluate the effectiveness of various preventive maintenance treatments in cold regions, including both dry-freeze and wet-freeze areas. To achieve this, the project will begin with a comprehensive review of state-of-the-art practices and established methodologies in preventive maintenance. Following this, the research will involve collecting long term pavement performance data on pavement conditions and preventive maintenance treatments. A questionnaire survey will be developed to gather information on current preventive maintenance techniques and their perceived effectiveness in cold regions across the United States. Statistical analysis will then be conducted to identify and assess the significant factors influencing the effectiveness of these maintenance treatments. The final objective is to evaluate the impact of different preventive maintenance treatments by measuring performance improvements or immediate enhancements in pavement conditions following treatment application.
