Abstract
An auxiliary hopper is attached to the rear of a cinder spreading truck. The auxiliary hopper carries salt. The cinders and salt are discharged from their respective storage hoppers in predetermined proportions, are mixed and dumped onto a spreader for application to the roadway. A hydraulic control mechanism allows continuous variation of the proportions of salt and cinders in the mixture applied to the roadway.
