Presentation Transcript

    2. AGRÈMENT CERTIFICATION OF THIN LAYER ASPHALT Ultra thin friction course layers have been constructed in Europe since 1990. Tens of millions of m2 have been paved. Most are produced under Agrément or similar certification

    3. USE OF UTFC LAYER

    4. AGRÈMENT CERTIFICATION OF THIN LAYER ASPHALT A system (layer + bond coat)

    5. AGRÈMENT CERTIFICATION OF THIN LAYER ASPHALT First Introduced in SA in 1998 Currently 2 proprietary products being produced under international licence SA designed and manufactured products also available.

    6. AGRÈMENT CERTIFICATION OF THIN LAYER ASPHALT PPGS ???

    7. AGRÈMENT CERTIFICATION OF THIN LAYER ASPHALT To develop performance criteria where, for proprietary and innovative construction products, there are no relevant standards

    8. AGRÈMENT PERFORMANCE CRITERIA FOR THIN LAYER ASPHALT Industry task team Joe Odhiambo Agrèment SA Joop van Wamelen Agrèment SA Basie Nothnagel ‘Agrèment’ Kim Jenkins Stellenbosch Univiersity Piet Myburg SABITA Elizabeth Sadzik Gautrans Dennis Rossmann SANRAL Mervyn Henderson PAWC Pat Olivier SAACE Gary Swart SAACE Derek Pretorius SAACE Julian Wise/Mike Winfield SAFCEC Wynand Steyn CSIR Benoit Verhaege CSIR

    9. CERTIFICATION PROGRAMME: TERMS OF REFERENCE (1) Both manufacturers and applicators must be included in the certification process (no split responsibility) Aggregate producers need to be included Certification process must accommodate possible different designs Procurement process for these products must be transparent to all stakeholders

    10. CERTIFICATION PROGRAMME: TERMS OF REFERENCE (2) Certification must be for specific uses of the product and must highlight inappropriate applications Quality management will be responsibility of manufacturer as well as applicator (either can be certificate holder) Certification will be conducive to consensus w.r.t performance guarantee requirements – certification will be an adjunct to the performance guarantee Certification will bring clarity on the durability or functional lifetime of the product. The certification process must be as cheap as possible (size of SA market)

    11. AGRÈMENT CERTIFICATION OF THIN LAYER ASPHALT International Scene BBA guidelines to serve as basis for Agrément SA performance criteria

    15. CERTIFICATION PROCESS Selected issues to be addressed: What is defined as thin-layer asphalt? European test methods adapted to SA standards Wheel tracking or MMLS testing Inclusion of mobile plants (project specific quarries) Appropriate application of products: Support stiffness/condition/porosity Traffic classes Surface texture (pre-treatment requirements) Quality assurance plans Performance property assessments

    16. CERTIFICATION PROGRAMME

    17. AGRÈMENT CERTIFICATION OF THIN LAYER ASPHALT UTFC layers:not “new” Certification: not “new” Certification will enhance “quality” Certification will promote transparent procurement
