Highways Agency 2007 national falling weight deflectometer correlation trials
The 2007 annual UK Falling Weight Deflectometer (FWD) correlation trial was held on the 24th and 25th April 2007 at TRL, on behalf of the Highways Agency. This is the eighth mandatory FWD correlation trial to be held in the UK with the objective being to monitor the performance of all FWDs (and Heavy Weight Deflectometers, HWDs) operating on the HA trunk road network. The performance of seventeen individual machines was assessed by examining and monitoring the results from the machines operating on specified test sections of the TRL Small Roads System (SRS). Only machines that are considered to have demonstrated satisfactory performance in the correlation trial are subsequently approved for use on the HA trunk road network. This report describes the conduct and findings of the correlation trial. (A)
