Partial Grouted Riprap for Enhanced Scour Resistance
Partially grouted armourstones combine the high resistance against currents and waves of large elements and their flexibility to adapt to ground deformations and the option of installing comparably thin layers. With partial grouting smaller and such often cheaper armourstones can be used to form conglomerates with the same resistance as large armourstones. Grouting can be done in fresh water and in saltwater. Segregation and erosion of the grout when poured or dumped or when fresh grout is loaded by currents and waves is avoided by using special chemical additives or by high speed centrifugal mixing (colloidal mortar) — common anti-wash-out mortar is not applicable. Stone diameters of 10 to 40 cm and a narrow rock size distribution are best for being grouted. To guarantee a successful application of partial grouted armours, a number of tests before, during and after installation have been established for quality assurance.
