DIN CEN/TS 12697-51*DIN SPEC 18099:2017-10

This Technical Specification describes a test method for measuring the surface shear strength for airfield surface courses, which is a measure of the robustness of asphalt surface courses against shearing. The surface shear strength will depend on the depth of the surface course together with the properties of the surface course material. The binder course material and any bonding agent applied between the two layers may have an influence on the test result for, in particular, ultra-thin surface course. NOTE The test was designed for use on airfield runways and taxiways.
