Vegetation Substrate with Lava Sand and Random Turf Fibers

The patent changes the physical and chemical parameters of the sand component by using lava sand instead of conventional quartz sand. The lava sand has specific grain size distribution (0-3mm), porous structure, and surface properties that enhance both turf surface stability and root zone anchoring. This parameter change resolves the contradiction by creating a substrate that simultaneously provides surface stabilization and root zone reinforcement without fiber damage during maintenance.

The patent creates a composite material system combining organic matter (topsoil and/or peat) with lava sand and artificial turf fibers. This composite paving material integrates multiple components with complementary functions: the organic matter provides nutrient and water retention, the lava sand provides structural stability and drainage, and the fibers provide tensile strength. The composite structure enables both turf surface stabilization and root zone stabilization simultaneously.

The patent changes the physical parameters of the sand component from conventional quartz sand to lava sand with specific properties: grain size 0-3mm, porous structure, and rough surface texture. These parameter changes enhance the anchoring resistance for roots while maintaining workability. The lava sand's surface characteristics provide better mechanical interlocking with roots and fibers compared to smooth quartz sand.

The patent utilizes the porous structure of lava sand to enhance root anchoring. The pores and cavities in the lava sand particles create mechanical interlocking points that increase resistance to root pull-out. This porous material property resolves the contradiction by providing superior anchoring strength while the particle size and shape maintain ease of mixing and transport.

The patent applies asymmetry by distributing artificial turf fibers randomly rather than in uniform vertical orientation. This random distribution creates asymmetric fiber arrangements that provide multi-directional support for root growth and stabilization. The asymmetric layout enhances root system stabilization by providing anchoring points in various orientations, while the lava sand matrix protects fibers from damage during maintenance operations.

The patent transitions from one-dimensional vertical fiber arrangement to three-dimensional random distribution within the paving material matrix. This dimensional change allows fibers to be embedded throughout the volume of the organic matter and sand mixture, providing stabilization in multiple directions and planes. The lava sand provides a protective matrix that secures fibers in this three-dimensional arrangement, preventing damage during maintenance.
