Recently Mohammed Faizan and Road Science's FWD machine got to spend time on the Chatham Islands. This was to complete some testing for the Chatham Island runway extension project. Over one day each FWD test point was subjected to 12 tests with the impact loads ranging from 40kN to 110kN to simulate aircraft wheel loads. The raw data was sent to Dr Greg Arnold to determine pavement layer modulus values for different loads to be used to optimise the pavement design of the new runway. Road Science's team has the only IANZ accreditation to test method (AG/AM:T006) in New Zealand. The team can deliver FWD data in raw f25 data files, back calculated moduli or incorporated into full pavement designs using in-house expertise. Get in touch with Jasen Schaaf jasen.schaaf@roadscience.co.nz or Nik Vishwanath nikhil.vishwanath@roadscience.co.nz for more information.
That's Fantastic! Remember back in my days at Downer putting a business case for an FWD, such useful data! Well done!
