What is PD CEN/TS 15901-14 - Procedure for determining the skid resistance about?
PD CEN/TS 15901-14 describes a method for determining the wet road skid resistance of a surface by measurement of the longitudinal friction coefficient, LFCN. PD CEN/TS 15901-14 is also used to determine the skid resistance on a surface covered by ice or snow.
PD CEN/TS 15901-14 provides friction coefficient measurements of the pavement by using an electrically braked test wheel. The test tyre is dragged over a pre-wetted pavement under controlled speed conditions while the test tyre is parallel to the direction of motion, and perpendicular to the pavement. Skid resistance measurement on winter roads do not require pre-wetted pavement.
To determine the macrotexture of the pavement, surface a laser system can be added. This system is placed in front of the towing vehicle in order to measure the macrotexture (mean profile depth — MPD) on dry pavements, and on the same path as the skid resistance measurement is done. Use PD CEN/TS 15901-14 guidelines for this measurement, and the devices are described in EN ISO 13473-1.
Who is PD CEN/TS 15901-14 - Procedure for determining the skid resistance for?
PD CEN/TS 15901-14 on procedure for determining the skid resistance of a pavement surface is useful for:
- Construction industry
- Civil engineers
- Airport authorities
- Road maintenance, and management authorities
Why should you use PD CEN/TS 15901-14 - Procedure for determining the skid resistance?
Through road/vehicle dynamic interaction, and vehicle vibration, the road profile evenness affects safety (tire contact forces), ride quality, energy consumption, vehicle wear as well as pavement, and road durability. The purpose of PD CEN/TS 15901-14 is to provide a standard practice for determining the wet road skid resistance of a surface by measurement of the pavement surface using the longitudinal friction coefficient.
Inadequate skid resistance increases the chances of skid-related automobile accidents, PD CEN/TS 15901-14 helps to assess skid resistance of roadways, and airfield surfaces for safety, and helps upgrade those roadways if needed.
