PROBLEM TO BE SOLVED: To easily control laying treatment, while an operator does not assume heavy responsibility of selection of a mechanical parameter.SOLUTION: Treatment when a layer is laid with a selectable pavement thickness S is controlled by using a road finishing machine with a floating screed, which has a screed provided with a pre-compaction system with at least one tamper, which enables the tamper to be operated at a selectable stroke H and a selectable frequency F, which enables a pulling spar to be adjusted by using a leveling cylinder, and which enables the height of the pulling spar to be adjusted at a fixed point by an ascending/descending cylinder. A target value of the pavement thickness S is input into an automatic closed loop control system; an actual attachment angle α of the screed, an actual pavement thickness S, and a laying velocity V are acquired and transmitted as information to the control system; an actuation signal is generated from at least the information transmitted by the control system, and transmitted to an actuation member; and the actual pavement thickness S is controlled to the target value. |
