This test method covers the determination of the interlayer shear strength of asphalt pavement layers using laboratory-prepared samples or core samples.
This test can be performed on 150-mm (6-in.) or 100-mm (4-in.) diameter specimens of asphalt pavement.
This test is applicable if the asphalt overlay layer and the base layer are both 50 ± 5 mm (2.0 ± 0.2 in.) thick. The total specimen thickness must not exceed 150 mm (6 in.). Layers may be saw cut to the recommended layer thickness.
