ABSTRACT:
Truck-transportable manually positionable apparatus for blending and dispensing a mixture of liquid asphalt emulsion and sand to fill cracks in pavement includes a support on which a sand hopper and blending/dispensing device are mounted. The device includes a housing having a rotatable sand impeller therein driven by a pneumatic motor and having a valved sand inlet port above the impeller, a pressurized air inlet port between the sand port and impeller (supplied from the same source as the motor), a mixture outlet port below the impeller, and a valved emulsion inlet port between the impeller and mixture outlet port. Gravity fed sand from the hopper is forcably propelled through the housing of the device toward the mixture outlet by the impeller and compressed air, and is mixed with emulsion just prior to exiting the mixture outlet port.
