ISO/TS 19708:2007规定了使用沥青混合料压路机测定联锁混凝土块路面中用作分离器的土工合成材料损坏的试验方法。土工合成材料放置在垫层砂层和基层粗料之间。压路机模拟公路交通荷载和行人荷载。在压路机试验后，确定保留的垫层砂。 ISO/TS 19708:2007可用于选择土工合成材料。

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.
