Abstract

A vehicle for transporting and dispensing materials required for filling and repairing cracks in roadways and highways or similar traffic-bearing surfaces comprises a supply tank for asphalt mix or emulsion or the like liquid crack-filling material, a hose leading from the asphalt supply tank to a dispensing area adjacent the vehicle, a directable applicator connected to the hose for directing crack-filling materials from the asphalt supply tank into cracks in the roadway, a resilient squeegee blade supported from the vehicle for dragging across the roadway dispensing area after crack-filler material is directed into cracks so that the crack-filler material is leveled, a hopper for carrying sand, rock chips, or other substantially dry structural material for covering the liquid crack-filler material and binding therewith to form in the aggregate substantially firm roadway surfaces, a dispensing broadcaster attached to the vehicle adjacent the dispensing area, and a conveyor interconnected with the hopper for moving sand or other structural filler material therefrom to the dispensing broadcaster.

Claims

1. A vehicle for transporting and dispensing materials required for filling and repairing cracks in roadways and highways or similar, said vehicle comprising;

a) a supply tank means mounted on said vehicle for asphalt mix or emulsion or the like liquid crack-filling material;

b) hose means leading from said asphalt supply tank to a dispensing area adjacent said vehicle;

c) a applicator means connected to said hose for directing crack-filling materials from said asphalt supply tank into cracks in the roadway;

d) a resilient squeegee blade supported from said vehicle for dragging across the roadway dispensing area after crack-filler material is directed into cracks so that the crack-filler material is leveled;

e) a hopper for carrying sand, rock chips, or other substantially dry structural material for covering the liquid crack-filler material and binding therewith to form in the aggregate substantially firm roadway surface;

f) a dispensing conveyance means attached to said vehicle adjacent said dispensing area; and

g) a conveyor interconnected with said hopper for moving sand or other structural filler material therefrom to said dispensing conveyance means broadcaster.

2. The vehicle for transporting and dispensing materials required for filling and repairing cracks in roadways and highways or similar as in claim 1, further comprising a pivotable arm connected between said vehicle and said resilient squeegee blades to allow the blade to be adjustably raised and lowered relative to the roadway.

3. A vehicle for transporting and dispensing materials required for filling and repairing cracks in roadways and highways or similar as in claim 1, wherein said resilient squeegee blade comprises:

a) a substantially rigid support blade supported horizontally disposed from said vehicle; and

b) a rubber blade suspended horizontally disposed from said support blade for flexible contact across the roadway.

4. The vehicle for transporting and dispensing materials required for filling and repairing cracks in roadways and highways or similar as in claim 1 and wherein said structural filler material is dispensed at least partially ahead of said squeegee blade in the direction of motion.

5. The vehicle for transporting and dispensing materials required for filling and repairing cracks in roadways and highways or similar as in claim 1 wherein said structural material is broadcast onto the roadway behind the squeegee.

6. A vehicle for transporting and dispensing materials for filling and repairing cracks in roadways as in claim 1 further comprising:

a) a supply tank for liquid hardening accelerator agent; and

b) hose means leading from said hardening agent tank to said dispensing area.
