Promotion of research and technology development
Development of snow removal vehicle driving support system
We are developing and trying a driving support system that guides the safe driving of snow and ice vehicles by combining a quasi-zenith satellite system that can obtain highly accurate position information and 3D high-precision map data.
(2) System development
By further utilizing the quasi-zenith satellite and technological development, we are working on supporting snow removal work at high speeds (about 50 km/h) and developing automatic steering technology for rotary snow removal vehicles.
Research on antifreeze agents
The "NEXCO EAST Research Center" introduced in Special Feature 3 (P21-22) is conducting research and technological development using corrosion acceleration testers and low-temperature constant humidity testers as an initiative to improve measures against snow and ice.
The corrosion acceleration tester is a device that accelerates the corrosion rate by repeating salt water spraying → drying → wetting, and tests and researches materials that are resistant to corrosion by spraying antifreeze agents. The low temperature and humidity tester is a device that reproduces the same situation as roads in winter by controlling the temperature and humidity, and further rationalizes and improves the efficiency of antifreeze agents, and conducts tests and research on frost damage and snow damage.
Road crack depth measurement technology (LCMS *) utilizing non-destructive inspection technology
A technology that estimates the crack depth from crack data on pavement without implementing traffic restrictions by using a test vehicle equipped with LCMS with the aim of saving labor in inspections and surveys on Expressway and advancing repair technology. Development is in progress.
* LCMS: Abbreviation for Laser Crack Measurement System
I am in charge of research / technology development and engineer training at the NEXCO EAST Research Center.
In research and technological development, we are working to improve the sophistication, efficiency, and safety of various snow and ice countermeasure work, such as further utilization of antifreeze agents and efficient spraying methods. Also, in the training of engineers, we try to develop engineers mainly for young people by giving them experience on site and giving them hands-on training using the facilities of this center.
