Highways England 2015 National Deflectograph Accreditation Trial

Because reliable survey data are crucial to road network maintenance, Highways England holds annual accreditation trials for its Deflectograph devices supported by quality assurance for the devices. The survey devices must meet the obligatory trial criteria to be allowed to perform accredited surveys on public roads. This report covers the 2015 trial run by TRL Limited, held on the HORIBA-MIRA proving ground, 3-4 March 2015.
