Abstract: In this study, the mechanical properties representing by tensile strength and elongation at break for the as-received steel reinforced rubber expansion joints were measured. Shore A hardness test was also measured. The tensile specimens were prepared according to ASTM D 4014. The results showed that steel plate reinforced rubber plays a significant role in stopping the crack initiating that occurred due to the continuous applied tensile load. The maximum tensile strength was reached of 16.73 MPa with a 456 % elongation at break and a shore A hardness value of 61.5 that gives the joints a superior durability and the required displacements of 330 mm in the bridge decks they are used to.
