• Abstract:
  A longitudinal joint is the interface between two adjacent and parallel hot-mix asphalt (HMA) mats. Inadequate joint construction can lead to a location where water can penetrate the pavement layers and reduce the structural support of the underlying base and subbase layers. ; Furthermore, water that penetrates asphalt layers may reside there and make the layers more susceptible to moisture damage through freeze-thaw cycling and/or subject the layers to large hydraulic loads if the water cannot dissipate quickly due to heavy loading.
