Geosynthetics in roads and pavements

Fabric Formed Revetments 

Fabric formed revetments (FFR) are constructed 

by pumping a very fluid fine-aggregate grout 

into a fabric envelope consisting of 2 layers 

connected by tie-chords or by interweaving. 

FFRs provide the durability of rigid linings, 

such as cast-in-place concrete or asphaltic 

concrete. FFRs can be engineered to perform as 

barriers or to be highly permeable, and they can 

be stiff or as flexible as  protective rock systems 

such as riprap or gabions.
