The PD CEN/TS 15901-15:2014 standard outlines a method specifically designed for airports to measure the skid resistance of pavements. The method employs the use of a trailer with a standard slip ratio of 15% to measure the longitudinal friction coefficient (LFCI) of a bound surface, providing a measure of its wet skid resistance properties.

The test involves dragging a test tyre over a pre-wetted pavement under specific conditions, including a constant speed and vertical force, with the test tyre positioned parallel to the direction of motion. The IMAG device is the specific equipment utilized for conducting the skid resistance measurements according to this standard.

The skid resistance of a pavement is determined through friction measurements at various speeds. While tests can be performed between 40 km/h to 120 km/h, the standard test speeds specified in the standard are 40 km/h, 65 km/h, and 95 km/h. These speed measurements allow for assessing both the microtexture (at low speeds) and the macrotexture (at high speeds) of the pavement surface. The skid resistance is reported as friction measurements at these speeds and is compared to a minimum friction level for evaluation purposes.
