Kampbell: “A fully structural rehabilitation means that the existing soil-structure interaction system has been renewed to its original structural functionality with a new service life; it’s water-tight and in a long-term stable condition. Any remaining competent material becomes a part of the new soil-structure interaction system once rehabilitation has taken place.”

What design approach should be used for manhole rehabilitation, and is ASTM F1216 applicable?
