| 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 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. |
