Crack router allowed for a more efficient use of labor by improving the maneuverability and reducing safety risks. In addition, based on the field operators' statements, the existing machine is difficult to pull and control, especially against strong winds created by nature or passing vehicles. On inclines, such strong winds can topple the router onto the operator. Comparatively, crack router requires a pushing motion rather than a pulling motion and does not have a mass large enough to be affected by wind, which allows for ease of control.
Therefore, crack router provides a safer working environment. In addition, crack router is much lighter than existing equipment and provides better control as to the desired depth cut for curved, random cracks. Overall, the crew determined that crack router could be considered as a supplement to the existing equipment.
