ROAD-MAKING MACHINE
An asphalt finisher (100) according to an embodiment of the present invention includes a travel switch (10) configured to start traveling, a hydrostatic transmission including a rear wheel traveling pump (14R) and a rear wheel traveling motor (20L, 20R), a pump regulator (15) configured to control the discharge quantity of the traveling hydraulic pump (14R), and a controller (30) configured to control the pump regulator (15) using a pump command current. The pump regulator (15) is configured to increase the discharge quantity of the rear wheel traveling pump (14R) as the current value of the pump command current increases, and the controller (30) is configured to increase the current value of the pump command current to a predetermined value smaller than a maximum current value in response to the travel switch (10) being turned ON.
