The invention belongs to the field of small-range gravel pavement, and particularly relates to a gravel spreading machine for road construction. The gravel spreading machine comprises a machine body, a walking module, a feeding module, an adjusting module, a finishing module and a control panel. The machine body comprises a rack and a hopper. The hopper is mounted on the rack. The rack is composed of a bottom plate and a side plate. A handle is arranged on the side plate. The walking module is mounted on the machine body. The feeding module comprises a conveying belt and a rake tooth unit. The adjusting module is used for adjusting the gravel spreading speed and range. The finishing module is used for repairing the surfaces of spread gravel. The control panel is used for controlling power of all the modules. The gravel spreading machine is mainly used for small-area gravel spreading, has the beneficial effects of being small in size, light and easy to operate, can automatically feed gravel of different types and can adapt to grounds in different shapes, meanwhile, the spread gravel is subjected to jolt ramming and finishing, the smoothness of a pavement face is guaranteed, and the work efficiency is improved.
