Polymer Modified Asphalt Expansion Joints

Polymer Modified Asphalt Expansion Joints (PMAEJ) is an asphaltic plug joint comprised of specially selected pre-blended aggregate designed to provide a tighter matrix of aggregate than conventional asphaltic plugs.

PMAEJ is installed in cutouts in deck surfacing ranging from 2 to 6 inches deep (5 to 15cm) and 20 to 24 inches (51 to 61cm) wide. The joint can be used for both expansion and fixed end joints at abutments or piers in many bridge types.
