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, 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. This ; project investigated the Notched Wedge Joint, as well as the traditionally used butt joint for comparison ; purposes. Two resurfacing projects were constructed in Connecticut during the 2006 paving season, and ; one in 2007, that utilized the notched wedge joint construction method. Nuclear density and volumetric ; density from cut cores along the longitudinal joints from these projects were investigated. Also ; investigated during the 2006 and 2007 construction season were resurfacing projects which utilized the ; traditional butt joint.
