Abstract

Laboratory testing is one of the tools one can use to predict the long term durability of armor stone. Along with testing of the stone, observations of the armor stones: rock type, bedding, quarrying methods, methods of handling and placement, inclusions, voids or vugs, saturation of the stone, clay content, overburden stresses, porosity of the stone, time of year of production, previous production methods, and experience of the quality control staff, should be used when making a determination the suitability of an armor stone source. These observations of armor stone, along with service comparisons of armor stone produced under similar conditions can be used to improve the selection of a source that produces armor stone that has the highest long term durability.
