NETC 99-2 Evaluation of Asphaltic Plug Joints

Asphaltic Plug Joints (APJs) are flexible asphalt segments that span between the bridge deck and abutment, serving as expansion joints. The advantages of using APJs are that they are quick and easy to install, they are easily repaired, they are not prone to snow damage, they may be cold milled when the road is resurfaced, and they are relatively inexpensive. The disadvantages of using APJs are that the performance of the materials is mainly a function of temperature... read more


Implementation of Superpave Technology in Massachusetts

Superpaveä is a comprehensive system for the design of Hot-Mix Asphalt (HMA) paving mixtures that are tailored to the unique performance requirements dictated by traffic (ESALs), environment (climate), and structural section at a pavement site. It is being used for steadily increasing shares of states’ asphalt pavement construction and rehabilitation projects... read more
