Fugro Aperio wins Traffic Speed Structural Survey (TRASS) contract in UK
Fugro Aperio has completed the latest Traffic Speed Structural Survey (TRASS) contract as part of the UK Highways Agency’s drive to implement annual structural testing on the English trunk road network.
Fugro Aperio, an approved tenderer for TRASS surveys, was awarded the work by TRL on behalf of the Highways Agency. The Cambridge-based survey specialist carried out the surveys in a two-month programme during February and March 2012.
The innovative TSD technology uses Doppler lasers to measure the speed at which the pavement deflects in response to load. The non-contact technology allows surveys to be conducted at up to 80 kph, vastly reducing the risk to motorists caused by slower moving deflection techniques such as deflectograph and falling weight deflectometer (FWD).
Data will be used to help service providers better identify and prioritise maintenance schemes as well as to help calculate the value of the pavement asset.
TRASS surveys have been underway since 2009, with the ultimate aim of using them for scheme level assessment and design by 2016.
TRL has been working on behalf of the Highways Agency since 2005 to develop and understand the data provided by the TSD and to build robust standard operating procedures for the equipment.
Part of the global Fugro group, Fugro Aperio provides geophysical and geotechnical investigations services for the near surface and built environment through three divisions – Transport, Structures and Ground.
