Tenders Are Invited For Research And Development Services And Related Consultancy Services – Procedure For Measuring The Grip Of Structured Markings And Coloring

Research And Development Services And Related Consultancy Services – Procedure For Measuring The Grip Of Structured Markings And Coloring. To Ensure Driving Safety, Especially For Motorized Two-Wheeled Riders, Sufficient Grip Must Be Ensured For Markings. The Srt Procedure Currently Contained In The Technical Regulations Is Not Suitable For Structured Road Markings Such As: B. The Agglomerate Markings Often Used On Federal Highways Are Suitable. There Is Therefore An Urgent Need For A Suitable Alternative To The Srt Method With Which Structured Markings Can Be Subjected To A Metrological Evaluation. In View Of The Increasing Importance Of Cycling, A Suitable Measuring Method For Red Colors, Which I.E. D. R. Also Have A Strongly Structured Surface, Desirable. Potentially Suitable Devices That Work According To The Longitudinal Force Method With Braked Slip (Lfc Measuring Method) Are Already Being Used In Other Eu Countries For Grip Measurements On Markings. In Addition To Covering A Larger Measuring Area Than The Srt Method, Continuous Measuring Methods Offer The Advantage That Microtexture Is Also Included In Addition To The Macrotexture. The Aim Of This Research Project Is To Develop Technically Suitable Processes According To The Above-Mentioned Method For The Structured Markings Used In Germany. Measuring Principle Must Be Identified And Validated. An Evaluation Background Should Be Created For The Proposed New Feature “Coefficient Of Friction Μ Of Structured Markings” And Separate Requirement Values ​​Should Be Recommended For Evaluating The Grip. In Addition, Test Instructions For Use In Practice Should Be Created. The Results Should Be Fed Into The Regular Revision Of En 1436. The Extent To Which The Procedures Can Be Used As Part Of The Aptitude Test Will Also Be Discussed.
