BS PD CEN/TS 12697-50:2016

BS PD CEN/TS 12697-50:2016 specifies a test method for determining the resistance to scuffingof asphalt mixtures which are used in surface layers and are loaded with high shear stresses in road orairfield pavement. These shear stresses occur in the contact area between tyre and pavement surfaceand can be caused by cornering of the vehicle. Due to these shear stresses, material loss will occur at thesurface of these layers. The test is normally performed on asphalt layers with a high amount of air voids(e.g. porous asphalt), but can also be applied on other asphaltic mixtures. Test specimens are usedeither 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 whereraveling is the normative damage criterion. The test can also be performed on other surface mixtures with a highresistance to permanent deformation. In case a mixture has a low resistance to permanent deformation, ruttingcan occur during the test. This can influence the test results.Cross References:EN 12697-6EN 12697-29EN 12697-33EN 12697-1EN 12697-12CEN/TS 13036-2ISO 48
