AI Technical Summary
Technical Problem
Existing asphalt finishers lack the capability to appropriately control their operation when the supply of paving material from transport vehicles is delayed, potentially leading to interruptions in construction due to insufficient material.
Method used
An asphalt finisher equipped with a control device that monitors the status of transport vehicles and adjusts its movement based on the supply of paving material, including stopping, decelerating, or accelerating to maintain continuous operation.
Benefits of technology
Ensures continuous and efficient construction by preventing material shortages and maintaining optimal operating conditions even when transport delays occur.

Abstract
Ensure that asphalt paver operation proceeds appropriately even if there are delays in the supply of paving materials. [Solution] The asphalt finisher 100 comprises a tractor 1, a hopper 2 installed in front of the tractor 1, a conveyor CV that transports the paving material in the hopper 2 to the rear of the tractor 1, a screw SR that spreads the paving material transported by the conveyor CV and scattered on the road surface in the vehicle width direction, a screed device 3 that levels the paving material spread by the screw SR behind the screw SR, and a controller 30 that controls the movement of the tractor 1 based on the status of the dump truck 200 that transports the paving material supplied into the hopper 2.
