- Abstract
This paper describes field and laboratory research on limestone riprap at a water retention dyke in northern Canada. Field studies over a period of 5 years showed that weathering had reduced the size of some of the riprap, and hence the protection offered to the dyke. Laboratory tests, including the Iowa pore index test, demonstrate the capacity of the riprap to resist deterioration caused by freezing and thawing. The field and laboratory studies have been complemented by demand calculations.
