Per ODOT 15.5.1.4 Riprap Backing, Riprap backing is either a riprap geotextile or a granular filter blanket placed between the riprap and underlying soil. The riprap backing acts as a filter and prevents the migration of fine soil particles through voids in the riprap. Table 15-6 lists the riprap backing requirements for each ODOT standard riprap class. Riprap backing is not required if the underlying soil meets the gradation requirements of the granular filter blanket. See table 15-6 for standard riprap backing classes (class 700).
