Advanced measuring equipment for cost-effective maintenance planning

Greenwood Engineering develops and manufactures advanced equipment for pavement condition measurements in the global road sector. All systems are designed to suit research level as well as routine survey operations. All system design and software are made in-house allowing for customized modules to be created to assure data continuity for the road administrations.

Traffic Speed Deflectometer (TSD)

The Traffic Speed Deflectometer (TSD), is an innovative Rolling Wheel Deflectometer measuring pavement response to applied load. The unique TSD technology is developed by Greenwood Engineering and has initiated a shift of paradigm in pavement engineering worldwide.

The Greenwood TSD provides continuous bearing capacity results at project and network level while following the flow of traffic. This makes the Greenwood TSD highly cost-effective.


The Profiler, also known as a profiler – is an advanced and accurate piece of equipment for pavement profile measurements. Subsystems, such as Right-of-way Imaging (ROW) and Surface Imaging System (SIS), can be added and synchronized with the profile data.


The LaserProf is a compact and portable profiler which can be mounted on a standard tow hitch. It can have one or two laser sensors and is designed to be a tool for the pavement supervision engineer making quality control before and after paving. The LaserProf has been implemented in the LaserProf BikeLaneTrailer for measuring bike lanes. GPS and Right-of-Way (ROW) can be added to the LaserProf.
