  "textContent": "The application relates to a self-propelled construction machine, in particular a road milling machine, recycler or stabilizer, finisher or roller, with a machine frame (1) on which a working unit (7) is arranged, and with a drive unit (12) for driving the working unit (7). In the construction machine according to the invention, an auxiliary substance, in particular a urea solution for operating an exhaust aftertreatment system (21), is provided in an operating fluid tank (20) which is integrated into the fuel tank (13) or the water tank (11) of the construction machine. The integration of the operating fluid tank into the fuel tank or water tank does not require any modifications to the machine frame, so that different production lines for construction machines with or without an exhaust aftertreatment system are not necessary. With the integration of the smaller operating fluid tank into the larger fuel tank or water tank, the dimensions of the construction machine can also remain unchanged, since the fuel tank does not require any additional space on the machine frame if the dimensions of the fuel tank or water tank are maintained.",
