AI Technical Summary
Technical Problem
Conventional techniques fail to replicate the raking work for efficient and high-quality finishing of pavement edges in asphalt pavement, leading to variations in finish quality and safety risks due to manual operations.
Method used
A pavement edge finishing device equipped with a rotating removal brush, suction means, and edge compaction means, connected to an asphalt finisher, automates the removal and compaction process, allowing for adjustable height and transverse movement, and uses thermal imaging for precise positioning.
Benefits of technology
The device mechanizes and automates the raking process, improving efficiency, reducing safety risks, and ensuring uniform finish quality by eliminating manual variations and collisions.

Abstract
This invention provides a pavement edge finishing device that enables more efficient and higher-quality finishing of pavement edges than conventional methods. [Solution] The system includes an excess aggregate removal means 12 that removes excess aggregate from the paving material by a rotating removal brush 123 at the side edge of the leveled asphalt pavement, an excess aggregate suction means 13 provided behind the excess aggregate removal means 12 and suctioning the excess aggregate removed by the excess aggregate removal means 12, and an edge compaction means 14 provided behind the excess aggregate suction means 13 and compacting the upper surface of the side edge of the leveled asphalt pavement by the vibration of a plate member 145, wherein the excess aggregate removal means 12, the excess aggregate suction means 13 and the edge compaction means 14 are connected to the rear side of the screed 2 of the asphalt finisher 1 via a connecting member 11.
