  1. Cooperation and technology transfer in pavement Engineering 2012 TRB International Partnership Meeting Leif Bakløkk NPRA

  2. Norway has a long tradition in using American technology and expertise in road engineering • USA has been a world leader in R&D in the area of road engineering • Many Norwegians have studied in USA • The Norwegian pavement design system is largely based on AASHO Road Test

  3. The cooperation between Minnesota and Norway is based on: • The generally close relation between Minnesota and Norway • Cooperation agreement (MOU) between MnDOT and NPRA as well as the annual meetings at TRB • Visit/exchange of personell • MnROAD • TERRA • BCRRA (Bearing Capacity of Roads, Railways and Airfields)

  4. What do we benefit from professional cooperation? • Generally higher knowledge/level of expertise. • Larger professional network. It is important to have someone to contact when new problems have to be solved and to know who has the knowledge on the various topics. • Provides us with bigger assurance that the solutions/methods we have chosen are right, and ideas on the possibilities for improvement. • This is well-invested money. In connection to European research it is estimated that for every penny we invest in such cooperation, we get 10 times back.

  5. What have we done last year? • Roger Olson visited Norway and Sweden in May 2011. Tour on Norwegian roads and professional discussion in Trondheim provided the basis for more topics for cooperation. • To persons from Norway participated in TERRA Board Meeting and MnROAD Research Conference in October 2011. Here several «Action Items» for further work were put forward. • All Nordic countries has provided their input to the work Ben Worel is doing on the «Comparison of Pavement Designs».

  6. Frost heave and temperature fluctuations: Topic for cooperation • In Minnesota low-temperature cracking is a big problem. We do not have much problem with this issue in Norway. • In Norway we still have significant problems with frost heave on many roads. MnROAD has data for frost penetration.

  7. Application of GPR for roads is another area that is well-suited for cooperation • 3D-Georadar which is developed in Norway is being tested by FHWA

  8. Other topics of cooperation in road engineering • Design of pavement structures • Pavement performance modelling • Material properties and requirements • Best practice (methods and materials) • Quiet Rumble Strips

  9. The cooperation in the future • Important to have continuity and specific (defined) topics of cooperation • Exchange and visit for students and professionals is also important • TERRA meetings/events • TRB • GPR-seminar April 18th 2012 Trondheim • BCRRA’13 Trondheim 25-27 June 2013
