1 A Southern European Approach The Portuguese Approach on Implementation of Harmonised European Asphalt Standards Dr. Maria C. M. Azevedo, CAeMD, Chairperson of Portuguese Technical Committees on Bituminous Binders and Mixtures 1

2 A Southern European Approach SUMMARY Portuguese vs. European Standards What Changes? Portuguese Design Methodology Conclusions: Impacts 2

3 A Southern European Approach Pyramid of demands User demands Structural performance Properties of base materials (bitumen, aggregates, ) CT 153/SC1 CT 154/SC Functional behaviour Characteristics of pavement materials (bituminous mixtures, ) CT 129/SC1 3

5 A Southern European Approach OTHER EUROPEAN BITUMINOUS MIXTURES EN Asphalt concrete for very thin layers Betão betuminoso rugoso com granulometria descontínua ou betão betuminoso contínuo EN Soft asphalt NOT USED EN Hot rolled asphalt NOT USED EN Stone mastic asphalt (SMA) STARTING 5

6 A Southern European Approach OTHER EUROPEAN BITUMINOUS MIXTURES EN Mastic Asphalt Mástique betuminoso EN Porous asphalt VERY USED, AT RAINY REGIONS OR FOR NOISE REDUCTION PURPOSES EN Reclaimed asphalt USED AS A CONSTITUENT IN RECYCLING TECHNIQUES 6

15 A Southern European Approach REQUIREMENTS AND APPROACHES FOR AC EVALUATION OF CONFORMITY AND CE MARKING LEVEL 1 EMPIRICAL APPROACH EXPECTED TO CHANGE FOR LEVEL 2 WITHIN THE NEXT 35 YEARS LEVEL 2 FUNDAMENTAL APPROACH TO START IN A NEAR FUTURE CONTRACT DOCUMENTS (SHW) LEVEL 1 EMPIRICAL REQUIREMENTS FOR THE MAJORITY OF WORKS LEVEL 2 FUNDAMENTAL REQUIREMENTS DEPENDING ON THE NETWORK IMPORTANCE; JOB SIZE. 15

16 A Southern European Approach SELECTIONS MADE EVALUATION OF CONFORMITY AND CE MARKING LABORATORY COMPOSITION VALIDATION (INSTEAD OF PRODUCTION COMPOSITION) SINGLE RESULT METHOD (INSTEAD OF THE MEAN OF FOUR RESULT METHOD) 16

17 A Southern European Approach PORTUGUESE MIX DESIGN METHODOLOGY (Impact) Marshall Tests (OPTIONAL) (OPTIONAL) 17 DEPENDING ON THE NETWORK IMPORTANCE ; JOB SIZE.

18 A Southern European Approach WHAT IS INTENDED NO duplication of work for CE Marking and for Specification for Highway Works Compliance purposes Specification for Highway Works may be more demanding: Product Control Tests Frequency Performance tests (stiffness and fatigue) Work complexity Work Importance 18

19 A Southern European Approach QUESTIONS Necessary a new audit of a NB always a mobile plant is relocated? If a mobile plant has a serious malfunction, the producer must ask an extraordinary audit to a NB? 19

20 A Southern European Approach CONCLUSIONS Need to review Contractual Documents Special work when defining requirements within fundamental approach 20
