Bituminous Mixtures - Test Methods - Part 49: Determination of Friction after Polishing
Also Known As:
The DIN EN 12697-49 standard outlines a test method for assessing the friction of bituminous mixtures after polishing. The aim of the test is to determine the friction at a speed of 60 km/h after a specified number of polishing passes have been made on the surface of the bituminous mixture samples. Additionally, this test method can also track the evolution of friction as the number of polishing passes increases.
The test samples used in this method can either be generated in a laboratory or obtained as cores from a construction site. It is important to note that this procedure was previously referred to as the Wehner and Schulze method. The standard provides detailed guidelines on how to conduct the test, ensuring that accurate and reliable results are obtained.
