Road managers know that the longitudinal joint is the first part of the pavement to fail. As a road’s most permeable part, this joint is susceptible to the elements. Air and water work down through this gap causing the joint to deteriorate, crack and pothole. And when the longitudinal joint fails, the rest of the road soon follows—triggering the need for even more maintenance.
