Development and Testing of Synthetic Riprap Constructed from Coal Combustion Products

Even with an increase in the amount of coal combustion products (CCPs) used in concrete construction, soil stabilization, and other applications, the coal power industry must dispose of a significant amount of fly ash and bottom ash. One potential avenue for the material is to develop a riprap to armor bridge abutments, bridge pilings, streambeds, and shorelines against scour and ice damage. The proposed research plan is divided into three (3) phases, which consist of the following: Phase I - Product & Criteria Development; Phase II - Prototype Development & Testing; and Phase III - Production Plant Design. Phase I involves determining the most appropriate applications for the synthetic riprap. There are several ranges of potential products available depending on the specific applications, including bridge pier scour prevention, channel stabilization, lake boundary erosion control, and shoreline protection. Once the potential product areas have been determined, the next part of Phase I will be to determine the necessary design requirements and specifications for the riprap. Phase II involves prototype development and testing based on the results from Phase I. Phase III involves development of a production plan and facility layout.
