  • Patent number: 9435085
    Abstract: Systems and methods for the slip forming of reinforced concrete composite structures for road and bridge construction, wherein each functionally discrete component of the composite has at least a portion of its reinforcement, in common with the reinforcement from an antecedent slip formed component of the composite. This system and method are, thus, suitable forming a composite having multiple functionally discrete components within an integrated/monolithic structure. The preferred system and method can sequentially form, in order, structurally discrete component parts for composite concrete road way structures having a road pad, (bridge) coping, traffic rail and barrier wall.

  • Patent number: 8956075
    Abstract: A slip-mold having a housing having (a) concrete hopper having (b) means for distribution of quick set concrete within said hopper, (c) a mold cavity, and (d) at least one tunnel, in communication with said mold cavity, and extending through said housing from the leading to the trailing end of said housing. The tunnel through the housing is of sufficient height and width, and positioned within said mold housing, to permit rebars, extending from an iron work array, to pass through said mold cavity without becoming embedded in concrete, concurrent with the formation of a slip formed concrete structure on a portion of said iron work array.
