Abstract
Systems and methods for applying roadway surface treatments. The system has an aggregate application assembly and a resin application assembly that are mounted or otherwise secured to a truck or other vehicle. The resin application assembly is spaced from the aggregate application assembly in the direction of travel of the vehicle. As the vehicle moves along a roadway surface, the resin and aggregate can be continuously applied such that the aggregate is provided to portions of the roadway surface that have been covered with resin.
Claims20
A system for applying a roadway surface treatment, the system being configured for coupling to a vehicle moving over a roadway surface in a selected travel direction, the system having a longitudinal axis parallel to the selected travel direction and comprising:
- at least one container configured to receive at least one resin or epoxy component;
- a spraying assembly positioned in fluid communication with the at least one container and configured to controllably dispense onto a roadway surface the at least one resin or epoxy component received from each container, wherein the spraying assembly comprises a plurality of spray nozzles, each spray nozzle comprising a spray tip;
- a hopper configured to receive and selectively dispense an aggregate material,
- a conveyor belt assembly configured to selectively deliver the aggregate material to the hopper,
- wherein the hopper comprises a gate that is selectively moveable from a closed position to an open position to dispense the aggregate onto the roadway surface at an aggregate delivery location,
- wherein the spraying assembly and the hopper are configured to continuously dispense the at least one resin or epoxy component and the aggregate material,
- wherein the spraying assembly is spaced from the aggregate delivery location in the selected travel direction such that the hopper dispenses the aggregate material onto portions of the roadway surface that have been coated with the at least one resin or epoxy component dispensed by the spraying assembly, and
- wherein a location of each spray nozzle of the plurality of spray nozzles relative to a transverse axis is selectively adjustable to modify a distribution pattern of the at least one resin or epoxy component, wherein the transverse axis is perpendicular to a vertical axis and the longitudinal axis of the system.

A system for applying a roadway surface treatment, the system comprising:
- a vehicle configured for movement over a roadway surface in a selected travel direction;
- a surface treatment application subsystem coupled to the vehicle, the surface treatment application subsystem having a longitudinal axis parallel to the selected travel direction and comprising:
- at least one container configured to receive at least one resin or epoxy component;
- a spraying assembly positioned in fluid communication with the at least one container and configured to controllably dispense onto a roadway surface the at least one resin or epoxy component received from each container, wherein the spraying assembly comprises a plurality of spray nozzles, each spray nozzle comprising a spray tip;
- an aggregate distribution assembly having a hopper configured to receive and selectively dispense an aggregate material;
- a conveyor belt assembly configured to selectively deliver the aggregate material to the hopper of the aggregate distribution assembly,
- wherein the hopper comprises a gate that is selectively moveable from a closed position to an open position to dispense the aggregate onto the roadway surface at an aggregate delivery location,
- wherein the spraying assembly and the hopper are configured to continuously dispense the at least one resin or epoxy component and the aggregate material, and
- wherein a location of each spray nozzle of the plurality of spray nozzles relative to a transverse axis is selectively adjustable to modify a distribution pattern of the at least one resin or epoxy component, wherein the transverse axis is perpendicular to a vertical axis and the longitudinal axis of the system.
6 more elements
A method of applying a surface treatment to a roadway, comprising:
- coupling a surface treatment application subsystem to a vehicle, the surface treatment application subsystem comprising:
- at least one container configured to receive at least one resin or epoxy component;
- a spraying assembly positioned in fluid communication with the at least one container and configured to controllably dispense onto a roadway surface the at least one resin or epoxy component received from each container, wherein the spraying assembly comprises a plurality of spray nozzles, each spray nozzle comprising a spray tip;
- an aggregate distribution assembly having a hopper configured to receive and selectively dispense an aggregate material;
- a conveyor belt assembly configured to selectively deliver the aggregate material to the hopper of the aggregate distribution assembly,
- wherein the hopper comprises a gate that is selectively moveable from a closed position to an open position to dispense the aggregate onto the roadway surface at an aggregate delivery location;
- moving the vehicle over the roadway surface in a selected travel direction;
- during movement of the vehicle in the selected travel direction, using the spraying assembly and the hopper to continuously dispense the at least one resin or epoxy component and the aggregate material onto the roadway surface, wherein the spraying assembly is spaced from the aggregate delivery location in the selected travel direction such that the hopper dispenses the aggregate material onto portions of the roadway surface that have been coated with the at least one resin or epoxy component dispensed by the spraying assembly;
- adjusting a location of at least one spray nozzle of the plurality of spray nozzles relative to a transverse axis to modify a distribution pattern of the at least one resin or epoxy component, wherein the transverse axis is perpendicular to a vertical axis and the longitudinal axis of the system;
- and
- during movement of the vehicle in the selected travel direction after modification off the distribution pattern to the at least one resin or epoxy component, using the spraying assembly and the hopper to continuously dispense the at least one resin or epoxy component and the aggregate material onto the roadway surface.
