Evaluation Of Pavement Edge Drains And The Effect On Pavement Performance, L. John Fleckenstein, David L. Allen, Jack A. Harison
Evaluation Of Pavement Edge Drains And The Effect On Pavement Performance, L. John Fleckenstein, David L. Allen, Jack A. Harison
Kentucky Transportation Center Research Report
This report documents the performance of highway edge drains in Kentucky. Approximately eighteen high edge drain installations were inspected. The report also documents the laboratory testing, construction, short-term and long-term performance of these systems. Construction inspection and maintenance are addressed.
It is apparent that the panels are distressed more under the old method of installation using excavated trench material and dynamic type compaction. It is apparent that using the sand slurry reduces the chances of installation damage. Proper density needs to be achieved during installation of the sand backfill or damage will occur due to trench settlement. In most cases, …
Follow-Up Inspection Of Premature Cracking On The National Turnpike, Jefferson County, L. John Fleckenstein, David L. Allen
Follow-Up Inspection Of Premature Cracking On The National Turnpike, Jefferson County, L. John Fleckenstein, David L. Allen
Kentucky Transportation Center Research Report
This report discusses the investigation of the premature cracking that has been occurring on the National Turnpike, Jefferson County since 1989. A report was issued in 1990, KTC-90-5. This report documents performance to date. A detailed distress survey was performed evaluating each slab throughout the project site.
The distress survey indicates that substantial pavement cracking has occurred since the last visual inspection in 1990.
An intense maintenance program is recommended.
