Claim:
1. 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 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 at least one longitudinal load-transfer member, the at least one longitudinal load-transfer member being incompressible, the at least one longitudinal load-transfer member having a longitudinal load-transfer member axis, the elongated core longitudinal axis and the longitudinal load-transfer member axis being parallel, the at least one longitudinal load-transfer member having longitudinal load-transfer member length, the elongated core longitudinal length and longitudinal load-transfer member length being equivalent, the at least one longitudinal load-transfer member bonded to the elongated foam core at the elongated core top, the at least one longitudinal load-transfer member 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 proximate a middlemost portion of the elongated foam core between the elongated core first side and the elongated core second side.
