When comparing the results of the test data shown in [Table 1] and [Table 2], first, the conventional Example 1 is made of a rubber chip as the main component is excellent in elasticity, but adaptability to bending or expansion and expansion according to temperature changes The resistance to the fall, the specific gravity is smaller than the water (1) there is a fear that the adhesion to the crusher layer due to the buoyancy when submerged. In addition, as shown in the results of the virtual experiment data in [Table 2], it can be seen that the water permeability is significantly decreased due to the pore blockage caused by the soil inflow over time.

Conventional Example 2 is composed of rubber chips and fine aggregates, which is resistant to warpage, but has a structure in which rubber chips are tightly wrapped around fine aggregates. Deviation may occur, and as the result of the virtual experiment data shown in [Table 2], it can be seen that the water permeability is significantly decreased due to the pore blockage due to the soil inflow over time.

In the elastic packaging material of the present invention, instead of the fine aggregates used in the conventional example 2, coarse crushed stone and fine aggregates were bonded to the rubber chip in an irregular shape, thereby increasing the resistance to warpage of the packaging material and increasing the resistance to stretching. In addition, the present invention shows 1.7 times higher water permeability than the conventional example 1 and the conventional example 2, as can be seen from the results of the experimental data of the above [Table 1] and [Table 2]. This includes a small perforated tube to prevent pore clogging due to conventional fine dust or soil inflow, thereby increasing the permeability.

As seen from the results of the above experiment, the present invention can ensure high water permeability and can improve the workability. This is due to the fact that the small perforated pipes act as connectors between the packaging materials to maximize the utilization of the voids.
