Fugro complete ‘7,000km’ TRASS contract

Fugro Aperio collected and processed data from up to 7,000km lanes of English trunk roads as part of a just completed Traffic Speed Structural Survey (TRASS) contract. The work, commissioned by TRL on behalf of the Highways Agency (HA), saw the Cambridge-based survey specialist gain information using the HA’s Traffic Speed Deflectometer (TSD). The innovative TSD technology uses Doppler lasers to measure the speed at which the pavement deflects in response to load.

2929 Fugro Aperio collected and processed data from up to 7,000km lanes of English trunk roads as part of a just completed Traffic Speed Structural Survey (TRASS) contract.

The work, commissioned by 777 TRL on behalf of the 2309 Highways Agency (HA), saw the Cambridge-based survey specialist gain information using the HA’s Traffic Speed Deflectometer (TSD).
The innovative TSD technology uses Doppler lasers to measure the speed at which the pavement deflects in response to load. The non-contact IT allows surveys to be conducted at up to 80kph, vastly reducing the risk to motorists caused by slower moving deflection techniques such as deflectograph and falling weight deflectometer (FWD).

The survey data, gathered over a two-month period during February and March 2012, is part of the HA’s drive to implement annual structural testing on the English trunk road network. It 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.

    Major progress has been made with regard to construction machine manufacturers agreeing on a standard for telematics communications. This is of key importance to contractors running mixed fleets, as data transfer from equipment will now be much easier. This progress has come with a new construction equipment telematics standard from the Association of Equipment Manufacturers (AEM) and Association of Equipment Management Professionals (AEMP). This has added key features to allow data gathering, and a test da

  • Steel wire barriers provide rock fall protection
    February 6, 2012
    In Gibraltar, where the entire population lives on or close to the huge limestone rock that gives the nation its name, the issue of rock fall protection is taken very seriously. Here, a scheme to install a network of rock fall catchment fences has just been completed, which will allow the re-opening of a critically important road at the south-eastern end of the Rock, which was closed following a significant rock fall occurrence in 2002.
