Asphaltic plug joint (also referred to as TST bridge joint) for movements up to 50 mm is a simple bridge expansion joint filled with asphalt. TST (crushed stone) elastic material is a special type of elastic-plastic material with high viscosity.

Aug 1, 2013 · Asphalt plug joints (APJs) have been used worldwide because of its low cost, ease of installation and repair, low instance of snowplow damage, low traffic noise and ride comfort. The service life of APJs is relatively short.

One of the most common bridge deck expansion joints is As-phalt Plug Joint (APJ). There are multiple advantages in using asphalt plug joints. APJ construction is quick and simple to install...

The asphaltic plug joints (APJs) are a type of bridge expansion joint that have been promoted as simple general purpose expansion devices for bridges with less than 50 mm (2 in.) total motion. APJs have been developed by trial and error and used when little engineering research existed outlining their complex behavior.

Mar 16, 2010 · Asphalt plug joints (APJs) have several advantages over traditional bridge joints. They are easy and cheap to install and have good surface flatness. However, widespread application of APJs in bridges has been hindered by frequently observed premature failures.

This specification covers the material, testing and application requirements for a field molded asphaltic plug joint (APJ) used in expansion joint sealing on asphalt concrete overlay and portland cement concrete decks.

Jun 11, 2015 · Two experimental bridges were constructed to present procedures for the design and construction of adequately sealed bridge joints. These procedures are offered as an interim solution.

Matrix™ Bridge Joints, also known as asphalt plug joints, are good quality closed joint solutions for new bridge construction or bridge rehabilitation. Matrix Bridge Joints can be used for expansion, fixed end, and pressure relief joints.
