1. International Pavement Engineering Meeting Use of GPR in Road Technology in Norway - Status Leif Bakløkk

2. GPR-activities in Norway 1.Participation in the Mara Nord nordic joint research project 2.PhD-study at NTNU on the use of 3D-GPR 3.Development at 3D Radar company in Trondheim

3. Mara Nord Project Developing joint Nordic action model for road condition monitoring with GPR method Funded By: Interreg IV A NorTh Programme; Regional Council of Lapland and North Calotte Council

4. Mara Nord Projects Purpose is to demonstrate the potential of the GPR method for monitoring and evaluation of the quality of the pavement and road structures in Finland, Sweden and Norway. The project purpose is achieved through cooperation between national transport administrations, universities, consultant companies and GPR manufacturers Project Purpose

5. Common Challenges The GPR method is complex The knowledge about the GPR method in Finland, Sweden and Norway are not equal The purchasing and controlling of the GPR services for Road administrations is difficult Selecting the appropriate measurement can be challenging for Road Administration The companies that provide GPR services need to meet different criteria's in each country that are not always even clear –For the equipment standards –For the result requirements Providing of the services across the borders are complex and less profitable because of different regulations and standards The licenses for providing GPR services are expensive and compulsory in Finland The void content measurement with GPR needed further developments

7. Partnership Transport Administration of Finland Transport Administration of Sweden Road Administraation of Norway Rovaniemi University of Applied Sciences Oulu University of Applied Sciences ELY center of Lapland

8. Project has support from business Finland –Road Consulting Oy –Road Scanners Oy –Carement Oy Sweden –RAMBOL Sverige AB –Malå GeoScience AB –Statens väg-och Norway –Sintef –3D Radar –NCC roads

9. Mara Nord has Achieved The trainings for Road Administrations have been provided The user trainings have been provided 4 of the 5 Joint recommendations are written –Use of GPR in pavement design and road rehabilitation projects –Use of GPR in bridge applications –Use of GPR in site investigation –Use of GPR in road construction quality control –Use of GPR in Asphalt quality control (is being written)

10. Mara Nord has Achieved Benchmarking of the equipment has been carried out the report is in editing and commenting phase Project has been promoted in different events of which the most meaningful are: –EGU 2011 Annual Conference –Publication for Non-destructive Testing Magazine –Project final publication is being prepared –Final Conference will be held in Spring (18 April 2012) in Trondheim, Norway Void Content measurement further tests have been carried out during the summer 2010 and 2011 the final report and publication is on its way Project has been recognized as truly cross-border practice that promote co-operation in the Interreg area

11. Use of 3D-GPR at NTNU/Sintef The equipment is used for many different measurement tasks on roads The PhD-program for Anne Lalague Anne would like a study period (6 – 9 months) in the United States as part of the PhD program
