Road surface construction quality monitoring device

The invention belongs to the technical field of pavement construction, and particularly relates to a pavement construction quality monitoring device which comprises a movable traction mechanism and a roughness self-checking mechanism connected to the rear side of the movable traction mechanism, a defect mark positioning mechanism is installed on the roughness self-checking mechanism, and the roughness self-checking mechanism comprises a hollow sliding seat. A fixing shell is arranged at the upper end of the hollow sliding seat, and two guide rods are fixedly connected to the side walls of the opposite sides of the fixing shell. According to the invention, self-induction identification can be carried out based on the change of the roughness of the asphalt pavement, a signal can be fed back in time to give an alarm, and rapid and automatic marking and positioning operation can be carried out when the roughness of the asphalt pavement is detected not to meet the use requirement, so that a worker can conveniently
