Abstract:Even with an increase in the amount of 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
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.
