15、Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.2 An articulating concrete block system is comprised of amatrix of individual concrete blocks placed together to form anerosion-resistant revetment with specific hydraulic perfor-mance characteristics.The system includes
16、a filter layercompatible with the subsoil which allows infiltration andexfiltration to occur while providing particle retention.Thefilter layer may be comprised of a geotextile,properly gradedgranular media,or both.The blocks within the matrix shall bedense and durable,and the matrix shall be flexible and porous.5.3 Articulating concrete block systems are used to provideerosion protection to underlying soil materials from the forcesof flowing water.The term“articulating,”as used in thisstandard,
