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. 1. 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 ...
