Gravel spreading rate quantitative detection method and device suitable for layer paving method

The invention discloses a rubble spreading rate quantitative detection method and device suitable for a layer paving method, relates to the technical field of road construction assistance, and solves the problem that the field rubble spreading rate is often judged by experience due to manual control, so that the control strength of the rubble spreading rate on a construction site is insufficient. The device comprises a master control device, a sanding device, a test box, an asphalt synchronous gravel sealing layer, an opening adjusting device and a conveying device, the master control device is connected with the test box through the transmission device, the sanding device is arranged in the test box, the asphalt synchronous gravel sealing layer is located below the opening adjusting device, and the opening adjusting device is connected with the master control device. And the height of the test box is adjustable. According to the invention, the spreading rate of macadam can be detected in real time and the sp
