The Matrix™ 502 Asphaltic Expansion Joint is a hot applied field molded and constructed expansion joint system that is composed of a uniquely formulated polymer modified asphalt binder that is mixed with specially selected and processed aggregate.
Live traffic can be released onto Matrix 502 about 2 hours after installation is complete if the blockout depth is 2". The deeper the blockout the longer the cure time.
Matrix™ 502 can be used for both expansion and fixed end joints at abutments or piers in many bridge types including concrete slab, concrete beam, prestressed concrete and steel beam, either simple or mulitspan, in both new construction and rehabilitation projects.
For more information on Matrix 502, please see our Specialty Expansion Joints Brochure or installation criteria and guides.
