Abstract
Three-dimensional aggregate reinforcement systems and methods thereof stiffen aggregate layers, such as those used for pavement construction. The system may include a substantially planar grid connected to a plurality of projections that extend into a third out-of-plane dimension. The system may be a self-projecting three-dimensional aggregate reinforcement system including a substantially planar grid which is generally two-dimensional before use, and which project into the third out-of-plane dimension after compaction with aggregate. The system may also be a self-projecting three-dimensional aggregate reinforcement system including a substantially planar grid with a plurality of first and second movable portions, where the second movable portions are more flexible than the first portion and may extend vertically and laterally upon addition of aggregate. Further, a method may include positioning a three-dimensional aggregate reinforcement system on the ground, adding aggregate to the aggregate reinforcement system, and compacting the aggregate.
