Expansion joint for longitudinal load transfer

An expansion joint system for imposition under compression between a first substrate and a second substrate, the first substrate and the second substrate being substantially co-planar with a first plane, the first substrate being distant the second substrate by a first distance, comprising:

• an elongated core,
• the elongated core composed of a resiliently compressible foam,
• the elongated core is coated with an elastomer,
• the elongated core having an elongated core longitudinal axis,
• the elongated core having an elongated core longitudinal length,
• the elongated core having an elongated core top,
• the elongated core having an elongated core bottom,
• the elongated core having an elongated core height intermediate the elongated core top and the elongated core bottom,
• the elongated core having an elongated core first side,
• the elongated core first side being generally perpendicular to the elongated core top,
• the elongated core having an elongated core second side, the elongated core second side being generally perpendicular to the elongated core top;
• the elongated core having an elongated core lateral width,
• the elongated core lateral width configured to be greater than the first distance prior to imposition, and
• three longitudinal load-transfer members,
• each of the three longitudinal load-transfer members being incompressible,
• each of the three longitudinal load-transfer members having a longitudinal load-transfer member axis,
• each of the elongated core longitudinal axes and the longitudinal load-transfer member axes being parallel,
• each of the three longitudinal load-transfer members having a longitudinal load-transfer member length,
• each of the three longitudinal load-transfer members bonded to the elongated foam core at the elongated core top,
• each of the three longitudinal load-transfer members spaced apart between the elongated core first side and the elongated cote second side,
• each of the three longitudinal load-transfer members having a longitudinal load-transfer member lateral width,
• wherein the longitudinal load-transfer member lateral width is not more than one-fourth the first distance and
• wherein the at least one longitudinal load-transfer member is formed in situ in an elongated core top slot in the elongated core top.
