The machine includes a body supported on three wheels with the front wheel being a steerable driven wheel. The body includes a storage tank for the liquid coating material. Support beams are pivotally connected to the rear of the body and extend rearwardly to support squeegees, a paddle wheel, and sand dispensing device. The sand dispensing device is driven by one of the rear wheels and is provided with a clutch so that the liquid asphalt coating material may be dispensed alone or in combination with the sand.
