About the Project

The Ohio DOT maintains 49,078 lane miles of highway, and has identified longitudinal joint failure of their asphalt pavements as a systemic weakness. To counter that, APTech worked with ODOT to develop guidance on how to choose the most appropriate longitudinal joint repair method and how to perform it effectively and at the optimum time to produce the greatest return-on-investment.

Our work included:

  • Evaluating the Ohio DOT’s current longitudinal joint repair processes.

  • Conducting a comprehensive study of longitudinal joint repair practices by other DOTs.

  • Modifying existing construction specifications and designer guidance.

  • Developing a guidance document to assist maintenance managers in making cost-effective repair decisions.

  • Developing a decision tree and treatment selection tool to be included in the Ohio DOT pavement management system.

  • Preparing a project report to summarize findings and provide recommendations.
