「In particular, during the current fiscal year, at a site under the jurisdiction of the Nagano National Highway Office of the Ministry of Land, Infrastructure, Transport and Tourism, we remotely operated an asphalt finisher from a technical research institute approximately 140 km away across the entire 300 m section at speeds equivalent to those of conventional paving operations, demonstrating implementation at a practical level.」
For remote operation of the asphalt finisher, we remotely operated the entire 300 m construction section from a research institute approximately 140 km away and demonstrated implementation at a practical level. - FY2024AdvancedAnnual report
「In the construction industry, initiatives to remotely operate and automate construction machinery are advancing in response to the need to improve productivity, address chronic labor shortages and comply with work-style reforms. We are developing a remote-control system for asphalt finishers, the central construction machinery used in paving work. Remote operation during mixture paving is now possible, and during the current fiscal year we conducted verification at an actual construction site and collected various data. Going forward, we will continue verification at construction sites and advance development with a view to ultimately achieving unmanned paving operations.」
Remote operation of the asphalt finisher has become possible, and development has progressed to the stage of on-site verification and data collection. Development is continuing with a view to unmanned paving operations in the future. - FY2022AdvancedAnnual report
「We developed a method for automatically controlling the finisher's paving speed based on the travel position of dump trucks transporting asphalt mixtures and verified its applicability at construction sites. For rollers, we developed a guidance system that improves smoothness by reducing the load caused by braking when the rollers turn around.」
We developed automatic control of finisher speed based on the mixture transport position and progressed to the stage of verifying its applicability at construction sites. We also developed a guidance system for rollers. - FY2020AdvancedAnnual report
「To improve pavement smoothness, we built a system to reduce the load on rollers when turning around and a guidance system for optimizing the speed of asphalt finishers. We are currently conducting on-site demonstration tests, the final stage of development, and have confirmed the improvement in smoothness.」
The pavement construction system using IoT, AI and other technologies has entered the final stage of on-site demonstration testing, and the improvement in smoothness has been confirmed. - FY2019AdvancedAnnual report
「We built a system that enables the travel position of compaction rollers and information such as turnaround positions at paving sites to be viewed on a tablet. Development of an overall pavement construction management system combining this system with information on dump-truck positions, the locations of construction machinery at paving sites and paving temperatures is also largely complete. We are also currently working to automate, using AI, crack analysis by the simplified road-surface measuring vehicle. In the three-level evaluation under the Pavement Inspection Guidelines, the accuracy of the crack analysis has reached a level that is almost fully consistent.」
The IoT-based overall pavement construction management system is largely complete, and crack analysis by the simplified road-surface measuring vehicle has progressed to AI-based automation and accuracy that is almost fully consistent with the three-level evaluation under the Pavement Inspection Guidelines. - FY2018AdvancedAnnual report
「As part of the introduction of IoT technology to road construction, we have been jointly developing with TOKYU CONSTRUCTION CO., LTD. a system for managing the transport and temperature of asphalt mixtures. We have now established a system that enables the temperature of asphalt mixtures in transit to be checked at any time on a tablet at the construction site, while also enabling optimization of the asphalt finisher's paving speed and real-time management of mixture temperatures.」
Development has progressed from the conventional mixture transport and temperature management system to the establishment of a system incorporating tablet-based checks at the construction site, optimization of paving speed and real-time temperature management. - FY2017AdvancedAnnual report
「As part of the introduction of IoT technology to road construction, we jointly developed a system with TOKYU CONSTRUCTION CO., LTD. for managing the transport and temperature of asphalt mixtures.」
The application of information-based construction and digital technologies has progressed to a system jointly developed with TOKYU CONSTRUCTION CO., LTD. for real-time management of the location and temperature of asphalt mixtures. - FY2016First statedAnnual report
「Application of CIM technology to paving construction and development and promotion of information-based construction」
The Company identified the use of CIM for safety, as-built and photographic management, machine control using GNSS, and control technologies for mini excavators as research and development activities.
