1. An expansion joint assembly comprising:

  • a pair of separate, adjacent, spaced apart concrete slabs having an elongated expansion joint therebetween;

    a pair of elongated load transfer bars each integrally formed and presenting a pair of opposed ends and a leg section extending from each end, one of said leg sections of each bar being embedded in one of said concrete sections in material consisting essentially of concrete, with the other leg section of the bar being embedded in the other of said concrete sections in material consisting essentially of concrete,said bars being oriented obliquely relative to said joint to cooperatively present a general X-configuration of bars bridging said joint, with the opposed leg sections of each bar being embedded in respective slabs,said load transfer bars being unconnected to each other throughout the obliquely oriented lengths thereof so that tensile and compressive loading is separately carried by each of the load transfer bars.
