Roads and highways

Safe roads and highways are a crucial elements of infrastructure. This applies to both new contraction of asphalt pavements as to maintenance, so it is important to keep a close eye on the condition of roads. Thereby the awareness among road authorities for a safe road surface also leads to an increasing demand for carrying out control measurement.

Kiwa can help and support in every step of the construction chain for both roads and highways. We have a number of testing systems, to test virtually all characteristics that may apply to the design, construction and management of roads, industrial sites and airports.

On site testing

Kiwa has the knowledge and newest equipment to test roads and highways on site. By international cooperation, we can offer our services Europe-wide.

With Europe’s largest skid resistance vehicle and the new 3D laser device, we offer lots of services with a high level of efficiency. All functional properties can be determined in just one run. We have developed our testing techniques which no longer hinder traffic:

• Texture
• Skid resistance
• Uneveness
• Ride comfort (IRI)
• Ravelling
• Road Markings
• Cracking
• Potholes
• and many more

Laboratory testing

Besides to the testing on site, we test all relevant properties of road construction materials in our own fully equipped and state of the art laboratories.
