PD CEN/TS 1269751:2017CEN/TS 12697-51:2017 (E) 6 1 Scope This Technical Sp
41、ecification 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 s
42、urface 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. 2 Normative references The following do

45、l shear strength between layers of an asphalt pavement and the torsional strength around the circumference of loading within the binder course Note 1 to entry: The surface shear strength will depend on the thickness of the surface course together with the properties of the surface course material, t
46、he binder course material and any bonding agent applied between the two layers. Note 2 to entry: The depth of the surface course will determine the extent to which the test measures the rotational shear strength between layers of an asphalt pavement or the torsional strength around the circumference
47、 of loading within the surface course. The greater the thickness, the less the test will measure rotational shear strength between layers. Note 3 to entry: If the thickness of the surface course is sufficiently shallow and the torsional strength of the binder course is sufficiently less than that of
48、 the surface course, the failure plane could go through the binder course. 3.2 surface course top layer of an asphalt pavement 3.3 binder course layer below the surface course, irrespective of whether it was originally intended to be the binder course and whether or not it is an asphalt layer 4 Principle A 100 mm diameter plate is bonded to the surface course and rotated using a torque meter to determine the torsional strength of the top layer and, in the case of ultra-thin surface courses, the rotational shear strength between layers.
