  • Methods and apparatus for repairing road surfaces
    Patent number: 11091885
    Abstract: Methods and apparatus for repairing road surfaces mix aggregate and liquified crack sealer on demand into mastic material for direct delivery to the road surfaces. Aggregate flows from a tilted box of a dump truck into a hopper and is conveyed by an auger into a tubular horizontal chamber. Liquified crack sealer is deliverable from a tank to the road surface or into the tubular horizontal chamber where it is mixed with the aggregate by a device into mastic material which is pushed through a vertical opening for delivery directly to the road surfaces. The frame which supports the hopper, conveyor, tank, and tubular horizontal chamber is movably supported on the road surfaces and is hitched to the dump truck.
