| Description: | Technical Report Abstract: The durability and size gradation of the rock materials are important aspects of construction of slope protection and dikes, jetties, and breakwaters. Some rocks are intrinsically susceptible to deterioration during service, while others are affected adversely by excessively close jointing in the source quarry. Elsewhere problems may arise from deficiencies in quarrying, processing, and handling, and in placement techniques. All 36 Corps of Engineers Districts in the continental United States and two operational Divisions have responded to requests for summaries and specific information on their experiences within the past 10 years. These data and observations made during field visits reveal causes of some problems and suggest some improvements; e.g., quarry examinations should be made in considerable detail, and representative samples for testing might be obtained from all major rock varieties. Although problems with stone quality and performance are so infrequent and minor that they are considered insignificant in about 80 percent of the Corps of Engineers offices, it is evident that an even further reduction in problems Corps-wide is attainable on future projects. Advances in the state of the technology will come both in laboratory testing and in the area of responsibility of the District geotechnical staff. |
