High-tech tools for advanced infrastructure management

The better a company knows the conditions affecting its structures and the reasons that can make them fail, the more successful its infrastructure management is likely to be. Roadscanners’ software gives road and rail engineers the tools to achieve this.

Roadscanners specialises in developing tools and services for monitoring and managing the structural and functional condition of key parts of transportation infrastructure, such as roads, streets, bridges, airport runways, and rail lines. This includes diagnosing the cause of problems in these areas once they have developed and advising how best to upgrade and strengthen structures.

Roadscanners’ expertise in the use of Ground Penetrating Radar (GPR) technology has become internationally renowned, as has its use of NDT methods to survey the mechanical properties of road construction materials. The company’s Road Doctor™ software family is used worldwide to process and interpret GPR data and can be very useful even when GPR data is not available, thanks to the software’s geographical information management, road survey data analysis, and road rehabilitation planning capabilities.

Keeping everything on track

Roadscanners’ RDMS® software can process and interpret field measurement data to produce an overview of the condition status of a rail network, analyse the reasons for distress in problem sections, present various rehabilitation measures and their estimated costs, and provide a GIS map-based overview.
Roadscanners has developed a number of new software tools over the last few years for monitoring the condition of rail structures and diagnosing problems associated with them. Railway Doctor®, for example, has been designed as an all-in-one package for the integrated analysis of standard railway survey datasets, while Railway Data Management System® (RDMS) focuses on rail condition surveys, reporting, and rehabilitation planning.

These tools enable rail engineers to analyse data parameters covering ballast and substructures in 2D or 3D quickly and reliably, and have been tested successfully in a number of countries in Europe, as well as South Africa, the US, and China.

Users of the software can work with multiple sets of data, such as GPR data, drill information, rolling stiffness results, and rail geometry measurements to locate problem areas and define the root causes of defects.

GPR and stiffness data is particularly valuable in analysing subsurface structures, while geometry information helps resolve problems at track level. Roadscanners’ software also enables this input to be used for drawing up cost-efficient rehabilitation plans and selecting long-lasting technical solutions for preventing recurring problems and for identifying structures and sections of track where preventive maintenance is required.
