The application relates to a brake oil pot, comprising an upper cup body, an oil return port, a first working oil port, a second working oil port, a lower cup body and an internal oil return port, wherein the upper cup body and the lower cup body are connected, the oil return port, the first working oil port and the second working oil port are arranged on the lower cup body, the first working oil port and the second working oil port are arranged on the two sides of the oil return port respectively, the internal oil return port is arranged in the lower cup body and is connected with the oil return port. The brake oil pot provided by the application has an oil return port, when the oil in the oil pot exceeds the highest scale line, the excess oil can flow back to the gearbox through the oil return port, so that oil spouting of the oil pot is prevented; the protective cover above the oil return port can prevent the oil in the brake oil pot from flowing back to the gearbox through the oil return port when the whole machine is jolted.

The present invention discloses a test device for evaluating the asphalt dosage of asphalt mixture, comprising a drying box, a rotating device is provided on one side of the drying box, a rotating rod is connected to the rotating device, one end of the rotating rod penetrates the side wall of the drying box and extends into the drying box, and one end of the rotating rod is detachably connected to a roller. Through the test device, during the rotation process, the excess asphalt binder, fine aggregate, mastic, etc. in the asphalt mixture sample can be fully contacted with the inner wall of the mixing barrel through continuous rotation, reducing the influence of factors of artificial sample loading, making the asphalt leakage test result more accurate, so that the asphalt dosage of the asphalt mixture can be more accurately and quantitatively evaluated, avoiding the impact of too small asphalt mixture dosage on the durability of the road surface, and avoiding leakage and oil overflow caused by too large asphalt dosage. Compared with traditional asphalt leakage test equipment, the test result is more accurate and the effect is more obvious.
