Long-Term Pavement Performance Data for Over 2500 North American Sections

More than 2500 pavement sections in the United States and Canada have been monitored for performance, construction, traffic, and environmental factors since 1990. The dataset, managed by the Department of Transportation, includes over a dozen experimental designs for asphalt and concrete pavements, with about one third of sections still active. New warm-mix asphalt concrete overlay sections are currently being added.

Use Cases

• Analyze Pavement Distresses data against Traffic Loading and environmental factors to model pavement deterioration.
• Compare the long-term performance of Asphalt Concrete and Portland Cement Concrete sections under different Maintenance and Rehabilitation strategies.
• Use Fwd (Falling Weight Deflectometer) data to assess structural capacity and predict remaining service life of pavement sections.
• Study the effects of Materials Testing results on Pavement Performance and Profile metrics over multi-decade time spans.

Strengths

• Longitudinal data collection spanning over 30 years, providing a rare long-term view of pavement behavior.
• Covers more than 2500 distinct pavement sections across the United States and Canada.
• Includes data from over a dozen experimental designs for asphalt, concrete, and rehabilitation strategies.
• Approximately one third of the sections are still actively monitored, indicating ongoing data collection.

Limitations

• The specific number of data rows and columns is unknown, making it difficult to assess the dataset's granularity and volume for analysis.
• Data is provided in HTML format, which is not ideal for direct computational analysis and would require significant parsing and cleaning.
• The license is listed as 'other-license-specified', requiring users to investigate specific terms and restrictions before use.
