Constructing High-density Longitudinal Joints to Improve Pavement Longevity
| 项目名称： | Constructing High-density Longitudinal Joints to Improve Pavement Longevity |
| 摘要： | This research would have three major objectives: (i) determine the factors that control the longitudinal joint density; (ii) develop a test method for more accurate quality control testing of the longitudinal joints; and (iii) develop a specification for longitudinal joint construction based on the findings of the research project. Failures around longitudinal joints (especially on roadway sections with centerline rumble strips) have been an important issue in Oregon affecting the overall long-term performance of Oregon roadway network. The longitudinal joint construction specification developed in this study will help Oregon Department of Transportation (ODOT) reduce the pavement cracking originating from longitudinal joints and improve the long-term performance of pavements in Oregon. Improved cracking performance will lead to reduced life cycle costs, increased pavement condition ratings, and reduced roughness for the Oregon roadway network. The longitudinal joint quality control test that will be developed in this study will help ODOT identify any issues with the joint construction practices in the future. |
