Bituminous Mixtures: Test Methods - Determination of Friction After Polishing

SKU164753548 Published by British Standards Institution BSI Publication Date2022-03-31 Pages CountPages32

BS EN 12697-49 is a European standard that specifically focuses on determining the friction after polishing for bituminous mixtures. It is part of the BS EN 12697 series, which covers various test methods for bituminous mixtures. This standard provides a method to measure the friction at 60 km/h after a fixed number of polishing passes on surfaces of bituminous mixture samples, or to track its evolution over the number of polishing passes. The samples used for testing can be laboratory-produced or taken from the actual site.

This standard is applicable to manufacturers of bituminous mixtures, construction engineers, quality control personnel, testing authorities, and regulatory authorities. It aims to establish a standardized procedure for measuring the friction after polishing of bituminous mixtures, ensuring consistency and accuracy in test results. The standard specifies the apparatus arrangement, explains the test principle, outlines the calculation process, and provides guidelines for reporting the test results.

The latest version of BS EN 12697-49, released in 2022, supersedes the previous edition from 2014. The updated version includes changes such as the removal of the term "hot mix asphalt" from the title, the addition of an introduction section providing context and the need for improvement in the test method, and the mention of the Wehner and Schulze method in the introduction, which allows for the possibility of tracking the evolution of friction after polishing. These updates ensure that the standard remains relevant and up-to-date in the field of bituminous mixtures testing.
