Bituminous Mixtures - Test Methods - Part 49: Determination of Friction After Polishing
Also Known As:
The DIN EN 12697-49 standard is designed to test the friction of bituminous mixtures after polishing. The purpose of this test is to determine the resistance of the mixtures to skidding or slipping on road surfaces. This is an important characteristic to evaluate the safety and performance of road pavements.
The standard specifies a specific method for determining the friction at a speed of 60 km/h after a fixed number of polishing passes on bituminous mixture samples. The samples can be laboratory-produced or cores taken directly from the site. The test allows for monitoring the evolution of friction as the number of polishing passes increases.
By conducting this test, professionals in the industry can assess the effectiveness of different bituminous mixtures in terms of maintaining safe and skid-resistant road surfaces. The results obtained from this test can guide decision-making regarding the selection of appropriate bituminous mixtures for certain road conditions and help in optimizing pavement design and maintenance strategies.
