Development of Delineator Material/Impact Testing Specific to Managed Lane Use for Optimization of Service Life.

摘要

The durability of delineators should be considered when selecting a product. Looking at the data gathered in the project, there was a considerable gap between the quality of the top three delineators tested and the other four. This led the researchers to recommend minimum average numbers of 150 tire impacts and 45 bumper impacts resisted as a pass/fail criterion for managed lane marker durability. This criterion would serve as a reasonable requirement ensuring that quality products meet a minimum threshold of performance. As the values are based on product testing, it ensures the criterion is an obtainable value for companies who intend to market their product for this application. The researchers developed a minimum requirement specification to ensure compliance according to the recommendations found within the report. This specification will help to ensure that the proper and more durable product is selected to be placed on Florida Department of Transportation roadways.
