Abstract
The sealant installer is pulled along the roadbed over the joint to be sealed and the installer wheel engaging the road surface on opposite sides of the joint slot pulls sealant by operation of teeth engaging the sealant through a lubricated feed chute which reduces the cross sectional width of the sealant to a size smaller than the width of the slot in the joint. Timing is assured without bunching or stretching of the sealant.
