The object of the present invention is to provide means for instantaneous control, and to change the sealant pattern length when applying asphalt sealant material. This is accomplished through integrating controlled actuated wings into a squeegee design, with an additional rotary actuator for additional rotation control. The present invention consists of a base mounting frame with means of mounting the apparatus to road maintenance machinery, a main squeegee frame, a squeegee wing actuator arrangement, squeegee blades, means of attaching the squeegee blade to the apparatus, and a rotary actuator attached to the main frame for additional control.
