NRV has specialized teams with long experience in carrying out inventory, pavement monitoring and road sign inspection, for which the company have all necessary equipment and technology for data collection, archiving and processing.
Data collection and inspection of elements that are part of the road infrastructure is held with the help of specialized software/hardware devices which represent information both in geographic and linear maps.
The road inventory can be achieved with different tools such as Astra Light or with Mobile devices.
High speed inventory allows data collection inside a vehicle while it runs the road along its side. Collected data is referenced to kilometre marks and to GPS coordinates.
For surveys with specific geographical requirements, data collection can be performed with Mobile devices with GIS real time tools.
We provide pavement monitoring services both in road and airport infrastructures. NRV | Norvia has the most recent technology for pavement structural and functional characterization using the following equipments: Falling Weight Deflectometer (FWD), Laser profiler (Longitudinal evenness / IRI - International Roughness Index), Laser Texture depth meter (macrotexture), Grip-tester (friction tester), Astra light, used in road inventory and photographic inventory. Data collected with these equipments is used for pavement management systems, road rehabilitation studies and for quality control during construction.
For the last 15 years NRV | Norvia has been developing various solutions of roads maintenance management and special attention has been given to pavement management systems.
The main goal for a management system is to formulate a road network maintenance programme, optimizing the costs of the intervention considering the required quality level.
Pavement Management systems can be applied to various types of infrastructures: highways, national and municipal road networks, aerodromes, airports and so on.
Since road signs play an important role as the link between the driver and the road atmosphere, its quality has great influence in road safety. We provide services road signs monitoring (both vertical signs and road marks) with equipment and devices specially conceived for this purpose. Road marks evaluation is achieved with a dynamic monitoring equipment known as ECODYN, a device that allows a continuous evaluation of longitudinal road marks, traveling at a speed of 80 to 120km/h. Vertical signs monitoring is performed with a static retroreflectometer that evaluates its night-time efficiency.
