ISO International Standard

ISO/TS 19708:2007 specifies a test method for the determination, using a roller compactor for bituminous mixtures, of the damage to a geosynthetic used as a separator in interlocking-concrete-block pavements. The geosynthetic is placed between a cushion-sand course and a base coarse material. The roller compactor simulates highway traffic load and pedestrian load. After the roller compactor test, the cushion sand retained is determined.

ISO/TS 19708:2007 can be used for selecting a geosynthetic.
