| 摘要： | 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. / NOTE: Final rept. / Supplementary Notes: See also PB2009-108856.
