ASPHALT FINISHER AND SCREED CONTROL METHOD
To provide an asphalt finisher and a screed control method which can overcome ground unevenness on site so that pavement surface can be finished flat.SOLUTION: An asphalt finisher 1 which has a traveling body 2, a screed 4, a leveling arm 5, a supporting shaft 6, a pivot cylinder 9 and a control device 19 further includes: a first detection part 15 which detects the height of a known first point with respect to the supporting shaft 6; and a second detection part 16 which detects the height of a second point positioned at a predetermined distance from the first point of the leveling arm 5. The control device 19 has a pavement design line 12a and controls the pivot cylinder 9 so as to change the position of the support shaft 6 based on the height change amount of the first point pavement design line detected by the first detection part 15 and the height change amount of the pavement design line of the second point detected by the second detection part 16, and is configured as such that an attack angle α on the bottom of the screed is maintained at a predetermined value.SELECTED DRAWING: Figure 1
【課題】現地盤の不陸をキャンセルし舗装表面を平坦に仕上げることが可能なアスファルトフィニッシャ及びスクリード制御方法を提供する。【解決手段】走行体２とスクリード４とレベリングアーム５と支持軸６とピボットシリンダ９と制御装置１９とを具備するアスファルトフィニッシャ１であって、支持軸６に対して既知の第１点の高さを検出する第１検出部１５と、レベリングアーム５の第１点から所定距離に位置する第２点の高さを検出する第２検出部１６とを更に具備し、制御装置１９は、舗装設計線１２ａを有し、第１検出部１５が検出する第１点の舗装設計線に関する高さ変化量と第２検出部１６が検出する第２点の舗装設計線に関する高さ変化量に基づき支持軸６を変位させる様、ピボットシリンダ９を制御し、スクリード底面のアタック角αが所定値に維持される様構成される。【選択図】図１
