1 Is Europe in Harmony The French National Approach Jean-Luc Delorme

2 The French National Approach Tests Main products NFP NF EN Guidance documents Contracts Conclusion

3 Tests used in France: Principle Type testing :Laboratory validation Conformity of the composition of finished product Bitumen content Grading curve Measurements in place Density thickness Macrotexture Permeability Eveness..

4 Tests for type testing Type testing Gyratory compaction Water sensitivity Rutting resistance Stiffness Fatigue resistance

5 Tests for type testing Type testing Gyratory compaction 0,82 Void content at a given number of gyration Water sensitivity Method B in compression Rutting resistance Large Device 60 C or cycles 10%; 7,5%; 5,0% Stiffness 15 C 10 Hz or 0,02s Complex modulus (2points) Direct Tensile Fatigue resistance Trapezoïdal-2points-10 C-25Hz ε6 Maximum density: method A in water

6 Type testing Gyratory compactor test serves as focal point of the method Void content by gyratory compaction Appropriate level of specification depending on Type and use of mixture Loading range Level 4 Niveau 4 Niveau 3 Level 3 Niveau 2 Level 2 Level 1 Niveau 1 Level 0 Fatigue Stiffness s Rutting resistance PCG, Gyratory Tenue à l eau Water sensitivity Empirical Fundamental Binder content, grading, additives
