Abstract:

Performance of Hot Mix Asphalt (HMA) longitudinal joints have 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 ; 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. Here, the Notched Wedge Joint is investigated along ; with the traditionally used butt joint for comparison purposes. 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. ; Also investigated during the 2006 construction season were several ; resurfacing projects which utilized the traditional butt joint.
