The glass fiber composite reinforcing material according to claim 1, further comprising: a resin reinforcing material 3 in the form of a grain composed of a polypropylene resin.

The present invention relates to a composite reinforcing material using glass fiber, and an asphalt mixture using the same, and more particularly, to a glass fiber composite reinforcing material composed of a pellet shaped scrap reinforcing material in which glass fiber scrap is coated with an outer covering material such as an asphalt binder or polypropylene and a rod-shaped fiber reinforcing material in which a plurality of glass fiber bundles are coated with a resin material, and contributing to improvement of various performances by being mixed in a hot-mix asphalt mixture, an asphalt mixture using the same, and a manufacturing method thereof.

In order to extend the service life of asphalt pavement, various methods have been introduced until now, wherein a method using a chemical modifier and a method using a geogrid are representative methods. The method using the chemical modifier is a method in which viscosity of an asphalt binder increases by melting petroleum-based SBS or SBR polymer particles in the asphalt binder. And the method using the geogrid is a construction method in which geotextiles woven in the form of a grid are installed in places.

This method exhibits advantageous effects of increasing reflective cracking resistance performance from a lower layer and rut resistance and the like, but there are weak points such as a construction period is prolonged since a construction process is complex, construction costs increase, and also when the highest stress concentration or shear deformation occurs inside 3 to 5 cm of a surface layer from an upper surface, actions therefor cannot be taken.

Besides, when bicomponent conjugated fiber for a hot asphalt Korean Patent No. The present invention is for solving the above problems, and an object of the present invention is to provide a glass fiber composite reinforcing material which is composed of composition in which a pellet or particle shaped reinforcing material using glass fiber scrap having economical and outstanding physical properties is mixed with a rod-shaped fiber reinforcing material made in the form of a bundle by coating several strands of glass fiber with a resin material such as polypropylene, can be conveniently injected at a hot-mix asphalt plant by having a specific gravity similar to that of a natural aggregate, and can improve the performance of an asphalt mixture by preventing the phenomenon of fibers becoming entangled within a produced hot asphalt mixture; an asphalt mixture using the same; and a manufacturing method thereof.

For achieving the objects, a glass fiber composite reinforcing material according to the present invention includes a pellet-shaped scrap reinforcing material in which glass fiber scrap made by pulverizing a bulk of discarded glass fiber, which is a byproduct in the middle of manufacturing a roving glass fiber, is coated with an outer covering material; and a rod-shaped fiber reinforcing material in which a glass fiber bundle having a plurality of glass fiber strands is coated with a resin material.

According to an aspect of the present invention, a hot-mix asphalt mixture which is made by mixing the composite reinforcing material, an aggregate, and an asphalt binder is provided. According to another aspect of the present invention, as a method for manufacturing the hot-mix asphalt mixture, a method for manufacturing the hot-mix asphalt mixture including a step of mixing a composite reinforcing material with an aggregate and performing dry mixing for a set time; and a step of mixing a mixture of the composite reinforcing material and the aggregate with an asphalt binder heated to a predetermined temperature and performing wet mixing for a set time is provided.

It can be seen that a hot-mix asphalt mixture mixed with the composite reinforcing material of the present invention has effects of increasing interlocking force between aggregates according to uniform dispersion of glass fibers, increasing the toughness of a mixture according to a bridging effect between aggregates, and increasing viscosity of an asphalt binder by a polypropylene resin.

As a result, when a road construction is performed using the hot-mix asphalt mixture according to the present invention, there are advantageous effects of increasing structural durability performance by solving problems such as plastic deformation, fatigue cracking, pothole damage and the like in addition to economic efficiency by not using a stone powder when a hot asphalt is produced at a plant. Hereinafter, an exemplary embodiment of a glass fiber composite reinforcing material according to the present invention, an asphalt mixture using the same, and a manufacturing method thereof will be described in detail with reference to the accompanying drawings.

Referring to FIG. The scrap reinforcing material 1 has a pellet or aggregate shape in a predetermined size by the glass fiber scrap being coated with an asphalt binder or a polypropylene resin. The glass fiber scrap is made in the form of fine powder by pulverizing, with a ball miller, the loss generated by cutting glass fiber strands in a process for producing glass fiber.

Although some of the glass fiber scraps are recycled, most are an industrial byproduct to be discarded. In the case of a particle size distribution of the glass fiber scrap, it is preferable that glass fiber scrap having a particle size distribution residual proportion in which a content of glass fiber which is maintained in the form of fiber having a thickness of 0. For this reason, in the present invention, a method in which glass fiber scrap is produced in a pellet or aggregate shape by being coated with an asphalt binder or polypropylene at room temperature, and then is mixed to an asphalt mixture has been suggested.

As a result, an amount of effective asphalt coated with an aggregate is caused to increase, and thus an advantage of preventing a pothole is provided. However, when glass fiber scrap is coated by mixing with an asphalt binder, manufacturing may become difficult due to manual asphalt binder coating, kneading compaction and the like.

To overcome this problem, as described above, glass fiber scrap may be manufactured in advance by being coated with polypropylene. That is, in the case of a general mix design of a hot-mix asphalt mixture, it has been prescribed that 20 to 30 kg of a stone powder per 1, kg of the weight of a mixture is used, and in the case of a glass fiber scrap reinforcing material 1 being substituted, there are advantages of being capable of producing a hot-mix asphalt mixture in a plant without an additional stone powder management and injecting process and being economical.

Meanwhile, the fiber reinforcing material 2 is produced using an extrusion molding machine as illustrated in FIG. It is preferable that the fiber reinforcing material 2 have a circular rod shape, but various shapes such as oval, polygon or the like may be formed.

It is preferable that an amount of glass fiber and polypropylene have a weight ratio of to 1. Such grains of a resin reinforcing material 3 composed of a polypropylene resin play an additive role when a final hot asphalt mixture is produced in a plant, thereby improving mixing workability of a mixture and viscosity of an asphalt binder referring to FIG. The glass fiber composite reinforcing material of the present invention composed as above works to improve performance of a mixture by being mixed in a hot-mix asphalt mixture.

A method for manufacturing the hot-mix asphalt mixture by mixing the glass fiber composite reinforcing material of the present invention in asphalt is as follows. First, a scrap reinforcing material 1 and a fiber reinforcing material 2 are mixed with an aggregate, and then dry mixing is performed for a set time about 30 seconds.

Through a dry mixing step of aggregate and reinforcing materials which have a similar specific gravity, the scrap reinforcing material 1 , the fiber reinforcing material 2 , and the aggregate are uniformly dispersed. As described above, when a hot-mix asphalt mixture is manufactured by mixing the glass fiber composite reinforcing material of the present invention with an aggregate and asphalt binder, an effect of glass fiber being uniformly dispersed in an asphalt mixture may be obtained because entanglement between glass fibers is prevented, and an economical effect may be also obtained because a hot-mix asphalt mixture may be manufactured without the use of a stone powder filler.

It was confirmed that a hot-mix asphalt mixture in which a glass fiber composite reinforcing material of the present invention Exemplary Embodiment 1 was mixed has effects of increasing interlocking force between aggregates according to uniform dispersion of glass fibers, increasing the toughness of a mixture according to a bridging effect between aggregates, and increasing viscosity of an asphalt binder by a polypropylene resin.

As a result, when road construction is performed using the hot-mix asphalt mixture according to the present invention, there are advantageous effects of increasing structural durability by solving problems such as plastic deformation, fatigue cracking, pothole damage and the like, and of economic efficiency by not using a stone powder when a hot asphalt is produced in a plant.

The hot-mix asphalt mixture in which the glass fiber composite reinforcing material according to the present invention is mixed is useable for a surface layer or a base layer of new asphalt road pavement, and also is useable as a material for an overlay layer when existing asphalt road pavement or plain concrete road pavement is repaired.

Particularly, when the hot-mix asphalt mixture is used for overlay repair in plain concrete road pavement in which transverse joints are formed, effects of reducing noise, roughness, easiness of maintenance and repair, economic efficiency and the like, all of which are advantages of general asphalt road pavement, may be expected, and also there is an effect of preventing reflective cracking mainly occurring at transverse joints in the concrete road pavement according to an increase in toughness of a mixture and viscosity of a polypropylene resin modified binder by the addition of glass.

Effects of a glass fiber composite reinforcing material of the present invention will be described in detail as follows. It was confirmed that there are effects of improving wet mixing workability by polypropylene PP of a scrap reinforcing material 1 and a fiber reinforcing material 2 , and of increasing viscosity of an asphalt binder. Thermoplastic polypropylene PP is composed of only carbon and hydrogen, and exhibits characteristics in which a specific gravity is 0.

A change in rheological properties of an existing asphalt binder Comparative Example 1 and the asphalt binder of Exemplary Embodiment 1 which is added with a scrap reinforcing material 1 and a fiber reinforcing material 2 , which are coated with polypropylene, was observed using a dynamic shear rheometer.

Through a test result of dynamic shear properties illustrated in FIG. Also, for confirming a property of increase in indirect tensile strength in Comparative Examples 1, 2, 3, and Exemplary Embodiment 1, a relative comparison of a completely dried sample and a sample subjected to a freezing and thawing process was performed.

A freezing and thawing process is performed in order to evaluate resistance performance of a mixture used at a construction site with respect to changes in outdoor temperature and moisture. In the case of indirect tensile strength of a completely dried sample referring to FIG. A reinforcement effect in Exemplary Embodiment 1 in which glass fiber is added is 2. In the case of indirect tensile strength of a specimen subjected to a freezing and thawing process referring to FIG. It can be indirectly seen that when the specimen of Exemplary Embodiment 1 reinforced by glass fiber and glass fiber scrap is subjected to a freezing and thawing process repeatedly, the specimen is still very effective.

Maximum indirect tensile strength is calculated while targeting a dried sample and a specimen subjected to a freezing and thawing process, and as a result, when the specimen of Exemplary Embodiment 1 exhibits maximum effects, a particle size of an aggregate may seem coarse grade and open grade. It is judged that a bridging effect is well exhibited by positioning glass fiber and scrap in pores of a coarse graded and open graded aggregate inside a specimen.

Therefore, the use of a glass fiber and scrap substituted mixture Exemplary Embodiment 1 is expected to exhibit greater effects particularly in mixtures such as a coarse graded mixture, stone mastic asphalt SMA , a drainage mixture, and open grade friction course, rather than in a dense graded mixture. The present invention has been described in detail with reference to an exemplary embodiment. However, it will be understood by those skilled in the art that various substitutions, additions, and changes may be made within a range without departing from the above-described technological spirit, and the changed exemplary embodiment is also included in the scope of the present invention defined by the appended claims.

DOI : Background: Additive Manufacturing AM enables the accurate fabrication of designed parts in a short time without the need for specific molds and tools. Although polymers are the most widely used raw materials for AM, the products printed by them are inherently weak, unable to sustain large tension or bending stresses. A need for the manufacturing of fiber reinforced composites, especially continuous fiber as reinforcement, has attracted great attention in recent years.

In one embodiment, the metal-coated sheet material is impregnated with a resin. According to embodiments of the invention, a metal is applied to one or two sides of the fabric or veil by a physical vapor deposition coating process. Materials used in the fabrication of component parts in the aerospace industry must have certain characteristics to protect the parts from damage or hazards caused by common environmental occurrences. If lightning strikes a wing component of an aircraft during flight, the event has the potential of causing a dangerous surge current in addition to causing serious physical damage of the component itself. The surge current is particularly concerning because it may eventually come into contact with a fuel reservoir causing an explosion to occur. As a result of an actual fatal plane crash caused by a lightning strike, the Federal Aviation Administration FAA implemented a system to categorize various zones for commercial aircraft based on probability and severity of being struck by lightning. Thus, it is crucial that such component parts are manufactured to have characteristics which, among other characteristics, prevent or alleviate damage caused by lightning strikes.
