It is possible to calculate the road surface profile and IRI over any interval! The process from measurement to analysis is systematized.
The "IRI Logger Lite" is a system that collects data from a non-contact speedometer and laser displacement gauge installed on a moving vehicle, allowing for the analysis and evaluation of IRI, road surface shape, and joint step shape using analysis software. It is capable of measuring road surface data (road surface profiles) at a speed of up to 60 km/h with a 10 cm pitch. By systematizing the measurement and analysis processes and utilizing specialized software, efficient data collection and organization can be achieved. 【Features】 ■ Measurement at a speed of 60 km/h ■ Detachable measuring instruments ■ Efficient data collection ■ Calculation of road surface profiles and IRI over arbitrary sections *For more details, please refer to the PDF document or feel free to contact us.
