  5. How Well Does It Actually Work ? • We don’t know how well GPS Controlled Spreading actually works • We have seen a lot of fine data but also some problems with data collection during the last 10 years • > Its time for testing !

  6. When We Do the Indoor Test… We do end up with two hours outside 15. September 2010

  7. Identifying a Nice Piece of Asphalt Nice Hotel Research Centre Byghom 700 Meter Asphalt – no Traffic

  8. My First Idea at a Closed Area…

  9. VTI: GPS Controlled Spreading

  10. Project Plan • Autumn 2009: Presentation of the test idea to the companies • Spring 2010: Detailed planning of the test procedure • May 2010: Test day: “Testing the test method” • June 2010: Test plan presented to the participating companies • The test week: 13.th – 17.th September 2010 • November 2010: Report ready for the companies for comments • January 2011: Final report published
