AI Technical Summary
Existing asphalt finishers struggle to lay pavement along curved roads, as the trajectory of the screed deviates from the desired path due to the tractor's center point drifting outward along curves, making it difficult to maintain the widthwise end surface of the pavement along the road's steps.
An asphalt finisher equipped with a controller that utilizes LIDAR and GNSS technology to monitor the road and adjust the steering automatically, ensuring the screed follows a predetermined trajectory or position, using hydraulic and electromagnetic control valves to align the tractor's center point with the target path.
The asphalt finisher effectively lays pavement along curved roads by maintaining the widthwise end surface alignment, preventing material overflow and ensuring precise pavement placement.
