1. A method for removing track-out from a vehicle, comprising:
aligning at least one track along an exit path of a construction site, the track having a plurality of substantially rigid crossbars secured within the track in a spaced-apart relationship;
receiving a moving vehicle onto the at least one track at a first end of the track and allowing the moving vehicle off of the track at the second end of the track;
vibrating the vehicle by moving the vehicle over the crossbars; and
shaking the vehicle in one of a hopping-up-and-down, a teetering-back-and-forth, and a teetering-side-to-side manner by moving the vehicle over the crossbars;
whereby the vehicle enters the construction site, picks up debris in the construction site during normal driving operation, and exits the construction site by passing over the at least one track in order to vibrate the vehicle and shake off the debris before exiting the construction site
dispersing below the track aggregate selected to be of a size and shape to provide spaces between the pieces of the aggregate;
forming channels by selecting the size and shape, and by thus providing the spaces; and
allowing the dirt that falls from the vehicle to move through the channels into the aggregate.
