Research And Development Services And Related Consultancy Services – Fe 06.0127/2026/Bgb - Creation Of A Performance-Based Evaluation Background For The Shaking Abrasion Method According To Tp Gestein-Stb, Part 6.6.3. The Water Sensitivity Of Third-Party Fillers And The Fine Aggregates Own Filler Has A Decisive Influence On The Mortar Properties Of Asphalt, Which In Turn Are Directly Related To The Usage Behavior Of The Building Material. In The Current Standard Din En 13043 Aggregates For Asphalt And Surface Treatments For Roads, Airports And Other Traffic Areas, The Water Sensitivity Of Third-Party Fillers And Proprietary Fillers Is Already Anchored As An Essential Characteristic. Research Work Has Proven The Suitability And Advantages Of The Shaking Abrasion Method For Determining This Water Sensitivity In Fine Aggregates. Based On These Findings, The D-A-Ch Countries Have Decided To Increase The Water Sensitivity, Tested Using The Shaking Abrasion Method. As An Essential Feature For The Fine Aggregate In The Ongoing Cpr Acquisition Process. However, A Central Problem In Deriving An Evaluation Background Directly From Test Sections Is The Long Lying Time Required, Which Makes The Process More Difficult. There Is Still A Need For Sound Scientific Substantiation And Optimization Of The Process. Part 6.6.3. The Specific Benefit Of The Fe Project Is That The Research Results Should Flow Directly Into The Technical Regulations (Tp Gestein-Stb, Tl Gestein-Stb). The Following Preliminary Considerations In Particular Can Be Taken Into Account In The Design Of The Processing: Ap 1 - Literature Study Wp 2 - Expert Survey Wp 3 - Optimization Of The Test Procedure Wp 4 - Evaluation Of The Optimization Wp 5 - Sample Characterization Wp 6 - Creation Of An Evaluation Background Wp 7 - Evaluation And Recommendations
