Evaluation of Longitudinal Joint Density Specification on 2012 Polymer Modified Warm-Mix Asphalt Projects in Connecticut-Final Report
in order to examine performance and establish future longitudinal joint density requirements on projects using Polymer Modified Asphalt (PMA), this study examines test data from several pilot projects that were constructed during the 2012 construction season on limited access highways in Connecticut. The current requirement for in-place longitudinal joint density on non-WMA/PMA projects is 91.0 percent maximum theoretical density. A major focus of this study was to determine if that requirement was achievable using PMA. Inspection of the project during construction revealed no indications of issues that may have contributed to lower in-place density. Core samples of the bridge deck and roadway longitudinal joints were collected from the projects and specimens analyzed. Based on these result, it is recommended that the specification for joint density on pavements using WMAP/PMA asphalt remain at 91.0 percent for roadway lots. The dataset from bridge deck joints is insufficient to make any recommendations.
