DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite material for pavement, and more particularly to a composite material for pavement having elasticity and water permeability by effectively using waste rubber and plastics, and a method for producing the same. is there.

[0002]

2. Description of the Related Art As a pavement composite material having elasticity and water permeability, rubber and plastic chips are used as an aggregate, and an upper layer material obtained by compression molding using a thermosetting urethane resin as a binder, and solidified molded water-permeable concrete. A material in which a lower layer material made of an epoxy resin is bonded with an epoxy adhesive is known.

[0003]

However, in such a conventional pavement composite material, since the upper layer material and the lower layer material are each bonded after solidification and molding, a sufficient adhesive force is exerted between the lower layer material bonding surface having many irregularities. However, there was a drawback that peeling was not easily obtained and peeling was easy.

Therefore, there is a method in which an adhesive is poured into the uneven surface of the lower layer material to improve the adhesive force by the anchoring effect. However, this requires a large amount of adhesive and requires a large amount of adhesive between the upper layer material and the lower layer material. There is a disadvantage that an adhesive layer is formed, and as a result, water permeability is lost even though the adhesive strength is improved.

The present invention has been made in order to solve such a drawback, that is, an upper layer material made of rubber or plastic chips as an aggregate and a lower layer material made of permeable concrete can be used without impairing water permeability. TECHNICAL FIELD The present invention relates to a composite material for glazing having elasticity and water permeability adhered to a material and a method for producing the same.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a sectional view showing a process of manufacturing a pavement composite material having an elastic surface layer according to the present invention, and FIG. FIG. 3 is a perspective view of the paving composite material that has been removed from the mold.

First, the manufacturing method will be described with reference to FIG. 1. An adhesive (3) having a viscosity of not less than 50 centipoise and not more than 100 centipoise is applied to a bonding surface with a roll coater or the like, and a solidified and molded permeable concrete block (1).

As described above, the particle size of the rubber or plastic chip used as the aggregate of the upper layer material is set at 1.0 mm.
By setting it to at least 10.0 mm or less, the mixing ratio between the aggregate and the thermosetting resin is 50 to 90% by weight and 5 to 90% by weight, respectively.

Further, the viscosity of the adhesive applied to the bonding surface of the lower layer material is set to 50 to 100 centipoise, and the mixture of the upper layer material is poured on the adhesive and heated and compressed, so that the adhesive strength and the appropriate strength can be obtained even if it is thin. It is possible to form an adhesive layer having a suitable water-permeable gap. In the experiment, it was found that the adhesive strength was reduced when the viscosity of the adhesive was 50 centipoise or less, and the adhesive strength was increased when the viscosity was 100 centipoise or more, but the adhesive layer was formed and the water permeability was lost.

In the following, a more specific example will be described. The adhesive surface of the lower layer material (1) of a solidified and molded permeable concrete block using quarry grains having a particle size of 5 mm to 10 mm as an aggregate has a viscosity of 50 centipoise.
