PAVING MACHINE, AND CALIBRATION METHOD FOR EMULSION SPRAYING SYSTEM MOUNTED ON PAVING MACHINE
PROBLEM TO BE SOLVED: To provide a paving machine capable of appropriately controlling an amount of sprayed emulsion, even when a property of the emulsion has changed.SOLUTION: A tack paver 100 according to an embodiment of the present invention has nozzles N1 to N3 for spraying emulsion, an emulsion pump 21 supplying the emulsion to the nozzles N1 to N3, and a controller 10 controlling an amount of the sprayed emulsion. The controller 10 includes a spray amount calculation part 12 that calculates the sprayed amount of the emulsion, and a calibration part 13 that makes the nozzle N3 spray the emulsion over a specified time period by controlling rotation of the emulsion pump 21, acquires the measured amount of the emulsion sprayed during the specified time period, deduces a relationship between pressure of the sprayed emulsion discharged by the emulsion pump 21 and the measured amount of the sprayed emulsion, and calibrates the spray amount calculation part 12 on the basis of the relationship.SELECTED DRAWING: Figure 2
【課題】乳剤の性状が変化した場合にも乳剤散布量を適切に制御できる舗装機械を提供すること。【解決手段】本発明の実施例に係るタックペーバ１００は、乳剤を散布するノズルＮ１〜Ｎ３と、ノズルＮ１〜Ｎ３に乳剤を供給する乳剤ポンプ２１と、乳剤の散布量を制御するコントローラ１０とを有する。コントローラ１０は、乳剤の散布量を算出する散布量算出部１２と、乳剤ポンプ２１の回転を制御して所定時間に亘ってノズルＮ３から乳剤を散布させ、所定時間に散布された乳剤の実測量を取得し、乳剤ポンプ２１が吐出した散布される乳剤の圧力と散布された乳剤の実測量との関係を導き出し、その関係に基づいて散布量算出部１２を校正する校正部１３とを含む。【選択図】図２
