To ensure the accuracy and reliability of the condition data, deflectograph accreditation trials are held annually by TRL on behalf of National Highways. By examining and monitoring the results from the machines operating on specified test sections, the performances of individual machines, and the whole UK fleet can be assessed. The 2022 trial was held in February on the twin horizontal straights of the Horiba-MIRA proving ground with TRL’s own deflectograph successfully passing the trial.
Deflectographs are also hired to assess stretches of the local road network, particularly in anticipation of pavement adaptation or modification, or to capture essential condition data to aid maintenance planning.
For more information about the service, and associated pavement surveys please visit the Solutions area of the TRL website.
