PD CEN/TS 1269750:2018CEN/TS 12697-50:2018 (E) 7 1 Scope This European Technical Specification specifies a test method for determining the resistance to scuffing of asphalt mixtures which are used in surface layers and are loaded with high shear stresses in road or airfield pavement. Th
41、ese shear stresses occur in the contact area between tyre and pavement surface and can be caused by cornering of the vehicle. Due to these shear stresses, material loss will occur at the surface of these layers. The test is normally performed on asphalt layers with a high amount of air voids (e.g. p
42、orous asphalt), but can also be applied on other asphaltic mixtures. Test specimens are used either produced in a laboratory or cut from the pavement. NOTE The test is developed to determine the resistance to scuffing for noise reducing surface layers where raveling is the normative damage criterion
43、. The test can also be performed on other surface mixtures with a high resistance to permanent deformation. In case a mixture has a low resistance to permanent deformation, rutting can occur during the test. This can influence the test results. 2 Normative references The following documents, in whol
44、e or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

47、ote 1 to entry: The amount of material loss can be determined in 3 different ways: visually and/or by taking pictures; by weighing the mass of the slab before and after the test: the difference in mass per area is a measure for the resistance to scuffing of the tested asphalt mixture; by scanning th
48、e surface of the slab before and after the test. The scans provide a 3D picture from the surface of the slab. After subtracting mathematically the 3D picture after the test from the one before the test, an accurate 3D overview of the material loss can be generated. The calculated volume of this 3D o
49、verview of the material loss is an accurate value for the resistance to scuffing of the tested asphalt mixture. Note 2 to entry: If permanent deformation occurs during the test, the results of the surface scan will be compensated for this phenomenon.
