Deflectograph surveys

Lincs Laboratory provides a comprehensive carriageway assessment service utilising its own Deflectograph, coring equipment and materials testing facilities.

All Deflectograph surveys and subsequent analysis of results are carried out in accordance with the Department of Transport Departmental Standard and Advice Notes.

Output is customisable to a format which suits the need of the customer. HMDIF files can be produced for loading data into a UKPMS Pavement Management System.

The survey speed is approximately 2.5km/hour and survey rates can be up to 15km per day depending on traffic conditions and working hours restrictions.

Surveys must be carried out under prescribed conditions defined by survey category.  The survey categories are defined in the current Department for Transport design manual (insert link)

UKPMS Visual Surveys

The United Kingdom Pavement Management System (UKPMS) is a standard for systems that assist in the management of the highway network.

Visual inspections are  carried out for performance monitoring and are also used, along with other surveys like Deflectograph, SCANNER and SCRIM, to assist with identifying and prioritising maintenance schemes.

There are two types of visual survey currently used:

  • Coarse Visual Inspection (CVI) - a simple, rapid survey carried out from a moving vehicle that allows large parts of the highway network to be assessed annually.
  • Footway Network (FNS) – a simple walked survey that identifies footways in need of more detailed investigation and potentially treatment.
