Grouted Riprap Design for Dams and Revetments
Grouted Riprap Design for Dams and Revetments
(OP)
Hopefully I am posting in the correct location. Is anyone familiar with design of grouted riprap for dam spillways or revetments based on expected overtopping flow velocities? I am trying to determine if there would be a considerable reduction in stone size and layer thickness between loose riprap and grouted riprap but I am having trouble finding information on grouted riprap. I would greatly appreciate it if anyone has some information (design manuals, examples, etc.) they could direct me to. Thanks!

The Corps only allows it in cases where large rock is not readily available or cost prohibitive. In general, this means rarely if ever. see the following corps document: ETL 1110-2-334 DESIGN AND CONSTRUCTION OF GROUTED RIPRAP
You might be able to use it for less critical applications. FHWA does allow it, but with little guidance.
