Abstract: A material calculator for a truck to deliver a predetermined quantity of brine per mile driven by the truck for a known route of miles independent of and proportional to truck speed, wherein the truck carries a known number of gallons of brine and a known number of pounds of salt. The material calculator has a processor accepting entry values of route miles to be driven, number of times the route of miles is to be driven, number of gallons of brine carried by the truck, and the number of pounds of salt carried by the truck. The processor has software for calculating dispensing of the brine and salt so that each is exhausted when the route is completed. A hydraulic pump pumps hydraulic fluid to a variable flow positive displacement pump to implement the calculated number of gallons of brine per mile to be dispensed for the known route.

Abstract: Disclosed is a system for precisely controlling distribution of saline, which employs a 6-bit manifold employing 6 solenoid valves for controlling the flow of hydraulic fluid therethrough. The manifold is in hydraulic fluid communication with motor valves. A mathematical formula or a lookup table determines the amount of saline distributed. The system is devoid of feedback. The 6-bit manifold can be employed on a salt spreader vehicle for controlling an improved flighted auger assembly for distributing granular salt from the rear of a salt spreader vehicle. The auger assembly has 3-stages of increasing diameter flights. The largest flight is at a discharge end of the auger assembly. A choke surrounds the ultimate auger flight at the auger assembly discharge end. The space between the choke and the ultimate flight is between about ? and ¼ inch.
