Abstract: A modular construction system that provides structures utilizable in the manufacture of bases for pavements, pavements, slopes, canals, walls, arches, and bridges. A flexible structure is obtained formed by the articulated and indissoluble union of a multiplicity of identical modular units that have articulated, unbreakable joints, although there are free spaces between the units, in such a way that when a weight is placed in any area of the flexible structure, a part of the load is immediately distributed to the adjacent areas, the structure thus resulting in a stress distribution system, being flexible, articulated, and indissoluble. The distribution of stresses occurs both in the horizontal and the vertical direction. Two or more structures can even be placed one on top of the other, duly articulated between each other, with a separating layer between each one of them, by means of latch pins such as to allow the structure to be flexible, functioning in a manner similar to how a single structure functions.

Abstract: A method and apparatus for constructing an articulating pavement comprising the placement in a first layer of a multiplicity of identically shaped foundation units on a subsurface. Each of the foundation units in the first layer is interlocked with adjacent foundation units in the first layer. Overlaid upon the first layer is a second layer of identical foundation units each of the foundation units in the second layer interlocked with adjacent units in the second layer. The units are shaped to create cavities between the first layer and second layer and between adjacent units in the first and second layers. Sufficient cement is then injected through orifices in the units to substantially fill the cavities. The cement is allowed to harden sufficiently to form latch pins which secure the units in an interlocked arrangement and articulatable in both the horizontal and vertical directions.
