ABSTRACT:
A highway coupling apparatus includes an expansion joint template, a plurality of rods, and a plurality of pipes. The template is positioned between longitudinal forms of a highway lane, creating two sections. After positioning the reinforcement bar in each section, the rods are extended through the expansion joint template and movably coupled to the pipes located in the second section. The highway coupling apparatus also includes a movement joint to couple adjacent lanes of the highway. The movement joint includes a plurality of eye bolts, L-bolts, movement joint templates, and a movement joint form. The eye bolts and L-bolts partially extend from the respective first and second lanes into the movement joint templates and are coupled. The movement joint templates are coupled to the movement joint form and prevent concrete from entering the eye bolt eyes during fabrication. After concrete is poured into the lanes and allowed to set, the expansion joint template and movement joint form are removed, resulting in an expansion groove and a movement joint groove. The grooves extend the entire depth of the highway and are filled with pitch to allow relative movement of the highway sections and lanes.
