ABSTRACT:
A prefabricated roadway expansion joint/load transfer assembly (10) is provided which accommodates normal expansion and contraction between adjacent slabs (90a, 90b) while transferring vertical shear loads and minimizing stress cracking of the surrounding concrete (90). The assembly (10) includes a plurality of X-configuration bar units (12) including crossed, unconnected metallic bars (20, 22) whose ends (24, 30, 28, 26) are embedded within the adjacent slabs (90a, 90b). The bar ends (24, 30, 28, 26) are coupled within the corresponding slabs (90a, 90b) through use of respective U-shaped coupling assemblies (14) each having spaced legs (38, 40) and a bight (42), and vertical tie rods (44). The individual bar units (12) are joined by laterally extending connecting rods (56-70). A central spacer (18) is supported by the bar units (12) and supplementary spring supports (76) and extends the full width of the assembly (10). In use, the cage-like assembly ( 10) is placed across a prepared road bed (88), and concrete (90) is poured over the assembly (10). The spacer (18) creates the necessary joint without the need for subsequent sawing of the concrete (90).
