• Abstract:
  Performance of hot mix asphalt longitudinal joints has been an item of increasing scrutiny in Connecticut. The traditional butt joint has typically been the method used in Connecticut. These joints have been reportedly opening up creating a longitudinal crack at the joint and thus contributing significantly to the premature failure of the wearing surface. It has been widely speculated that alternative longitudinal joint construction methods could be employed to reduce the rate at which joints fail. In this research, the notched wedge joint is investigated. Two resurfacing projects were constructed in Connecticut during the 2006 paving season that utilized the notched wedge joint construction method. These projects were investigated as to their nuclear density and volumetric density from cut cores along the longitudinal joints.
