The project is 120km south of South Korean capital Seoul and involved paving testing ground access roads for Hankook Tire. Also included was paving work adjacent to the main test roads, with the work being carried out by local contractor Daero Constructio. The paving crew used a MOBA Big Sonic Ski with sensors to ensure accurate placement and smoothness. The ski can work as wide as 13m, though this project called for passes of 12m. The crew worked at a pace of around 5m/min, placing roughly 200tonnes/hour.
The AFT 700-3 was equipped with a high-compaction screed, which employed tamping and vibrating features as the mix was placed. The operator, Mr Baek, praised the ease of the use of the machines' PaveManager 2.0, a CAN-based automated system that monitors paving and provides feedback. PaveManager 2.0 is connected to both the main operator control and to the screed remote control panels, providing an overview. It automates many key functions and allows slope and/or crowning to be programmed.
Baek also appreciated the ease of operation resulting from the integration of the auger and sonic sensors. A reversible twin conveyor system allows material to flow consistently from the hopper. The tunnel-shaped material conveyor helps optimise flow and limit segregation. The auger system delivers consistent distribution of material across the screed. The system features sonic sensors that provide proportional speed control.
