Before carry out the crack filling construction, road maintenance personnel need to check the width of the crack needed to be repaired and see if the seam needs to be widened. If the crack is too small, they use the crack router extended to the appropriate depth and width of the construction joints.

Clean the cracks and then repair it with asphalt sealcoating equipment. Ensure that the crack is as clean as possible -- free of stray concrete, dirt, or plantlife -- by using a wire brush and canned air to remove

After pouring the cracks, spread the preheated stone chips on the cracks evenly, so as to complete the work of repairing asphalt cracks.
