-Roadway cracking pavement material-

Specifically, the pavement aggregate is configured to secure the physical strength of the pavement for bicycle road according to the present invention, the steelmaking slag is refined pig iron, commonly referred to as 'steelmaking slag' in the converter carbon, phosphorus and sulfur as impurities It is a material that is generated during the process of removing the material, somewhat less than the general aggregate material pavement, but has a strength similar to that of the configuration to realize the main strength of the crack-proof pavement 40 for the bicycle road.

At this time, the steelmaking slag, as mentioned above, somewhat less strength than the pavement aggregate, which is a construction material of the general silicon material, water is excellent on the surface of the crack-proof pavement 40 for the road construction completed by excellent permeability The effect of preventing accumulation can be realized.

In addition, the steelmaking slag according to the present invention may use the steelmaking slag itself discharged from the steelworks, or may use a steelmaking slag processed by chemically stabilized steelmaking slag by a predetermined method.

That is, when using the steel slag itself is discharged from the steel mill, it is preferable to have an average particle size of 80% or more in the 1.5mm sieve, and 100% in the 5mm sieve.

Specifically, if the average particle size of the steelmaking slag has a size of more than 5mm, the permeability of the construction of the crack-resistant pavement 40 for the finished road is improved, but the problem that the surface of the pavement is unevenly crushed steelmaking slag If less than 1.5mm, the voids generated between the steelmaking slag particles is dense, the strength of the construction of the crack-resistant pavement for road 40 completed is excellent, but there is a problem that the water permeability of the packaging material is insufficient, the present invention It is preferable to use steelmaking slag having an average particle size in the range of 1.5 to 5 mm.

In addition, when using a steelmaking slag processed by a certain method, it is preferable to use a PS ball (Precious slag ball) produced by a processing method generally known as slat atomizing technology (SAT).

That is, the SAT generally refers to a method of processing using a processing equipment known as a SAP (slag atomizing plant), and the particle size is relatively high by rapidly cooling the steelmaking slag of 1,300 ° C or higher and simultaneously applying a strong wind to the steelmaking slag. By crushing large steel slag, the steelmaking slag is a spherical PS ball having a chemically stable small particle size.

In addition, the present invention preferably uses the PS ball having an average particle size within the range of 1.5 ~ 5mm, which has the same reason as using the steelmaking slag discharged from the steelworks, specific description thereof Instead of the above description.

In addition, the steelmaking slag according to the present invention preferably has a composition ratio of 65 to 75% by weight of the total weight of the anti-cracks pavement 40 for bicycle roads, the general domestic waste melting slag or blast furnace slag 40% by weight or more in the road pavement When included as, the problem that the strength of the road pavement is insufficient due to foreign matter between the slag and other aggregates (silica, gravel or soil) occurs, the present invention is able to secure a certain strength through the following polyurethane binder , Road bike crack prevention packaging material 40 may include more than 65% by weight steelmaking slag.

That is, the crack prevention pavement material 40 for the bicycle road of the present invention may contain less than 65% by weight of steelmaking slag, but if the steelmaking slag is mixed at less than 65% by weight, there is a fear that the effect of improving water permeability by steelmaking slag is insignificant. If it exceeds 75% by weight, the composition of the steel slag is excessively excessive so that the strength of the construction of the crack-resistant pavement 40 for the completed roadway is weakened, so it is preferable to have a composition ratio of the above range ash.

In addition, the natural silica included in the paving aggregate is to reinforce the strength of the construction of the crack-resistant pavement 40 for the completed road, to prevent cracking, and to reduce the amount of drying shrinkage of the polyurethane binder generated by curing the polyurethane binder As a configuration, general road pavement natural silica may be used, and one having various particle sizes may be used according to the judgment of those skilled in the art, but it is more preferable to use one having a particle size similar to that of steelmaking slag.

In addition, the composition ratio of natural silica to the total weight of the bicycle road crack preventing pavement 40 is preferably 20 to 30% by weight, if the natural silica is included in less than 20% by weight, the construction of the crack prevention pavement for the road completed The problem of the strength improvement effect and the crack prevention effect of (40) and the decrease in the drying shrinkage amount of the polyurethane binder are insignificant, and when the weight exceeds 30% by weight, the expected effect is excellent, but the crack for the bicycle road Since the adhesive force of the prevention packaging material 40 is lowered or the mixing with other compositions of the crack prevention packaging material 40 for bicycle roads occurs smoothly, it is preferable to have a composition ratio within the above range.

In addition, the polyurethane binder of the present invention is to allow the steel slag and natural silica to be bonded to each other, and to prevent the crack road pavement 40 for a bicycle road to have a certain adhesive strength, adhesive strength, tensile strength, impact resistance, wear resistance and An effect excellent in physical properties such as durability can be obtained.

At this time, the polyurethane binder of the present invention can be used in the pre-production by a general manufacturing method, in consideration of the mixing of the packaging aggregate according to the curing time and degree of curing of the polyurethane binder having a curing time of about 12 hours, It is preferable to mix and use a polyol and an isocyanate resin in an appropriate composition ratio at the time of construction before mixing with a packaging aggregate.

Specifically, the polyol (polyhydroxy compound) may be used any one or more of those having generally known functional groups and hydroxyl groups, more preferably 2 to 6 average functional groups and the average of 20 to 1000 mgKOH / g It is preferable to have a hydroxyl group.

At this time, the functional group is a common atomic group that causes the chemical properties of the polyol, and by shortening the chain length (chain length) between the functional groups by using an average number of functional groups of 2 to 6, the crosslinking density of the polyurethane binder increases. By doing so, there is an effect that the prepared polyurethane binder has an excellent strength.

In addition, the hydroxyl group is an addition polymerization reaction with an isocyanate group (-NC = O) of an isocyanate resin, and an average hydroxyl group is used with an isocyanate resin using an average hydroxyl group having 20 to 1000 mgKOH / g. It is desirable to increase the crosslinking density so that the finished polyurethane binder has excellent strength.

In connection with the above, the polyol according to the present invention may be used in general, but as described above, a polyether polyol, a polyester polyol or a polyester polyol having an average functional group of 2 to 6 and an average hydroxyl group of 20 to 1000 mgKOH / g. It is preferable to use any one or more of them.

In addition, the isocyanate resin reacts with the polyol of the resin mixture resin to form a urethane bond, in which an active hydroxyl group (-OH) of the polyol and an isocyanate group (-NC = O) of the isocyanate resin are added. Addition Polymerization Reaction

At this time, the isocyanate resin may be a general isocyanate resin, but dimethyldi isocyanate, methylene diphenyl diisocyanate, hexamethylene diisocyanate, aromatic polyisocyanate, 2,4- or 2,6-toluene diisocyanate (TDI), 4 MDI derivatives made of, 4'-diphenylmethane diisocyanate (MDI) or 4,4-diphenylmethane diisocyanate; It is preferable to use any one or more of the crude MDI composed of a dimer or trimer of the MDI derivative to smoothly generate carbon dioxide so that the polyurethane binder can have a predetermined adhesive force and a predetermined elastic force at the same time. .

In addition, the composition ratio between the polyol and the isocyanate resin may have an appropriate composition ratio according to the judgment of those skilled in the art, but it is preferable to have 100 to 120 parts by weight of the isocyanate resin with respect to 100 parts by weight of the polyol.

At this time, it will be apparent that the polyurethane binder of the present invention may further include a certain amount of a physical auxiliary agent such as a catalyst, a foam, a crosslinking agent, or a flame retardant according to the judgment of those skilled in the art.

In addition, the polyurethane binder of the present invention having the configuration as described above preferably has a composition ratio of 3 to 5% by weight relative to the total weight of the anti-cracks pavement 40 for the bicycle road, the composition ratio of the polyurethane binder is 3 weight If less than%, the composition of the polyurethane binder to the packaging aggregates is insignificant, resulting in a problem that the bonding strength between the packaging aggregate particles and the adhesion to the following geogrid 30 and the foundation ground 10 falls, and exceeds 5% by weight Too much mixing amount of the polyurethane binder to the paving aggregates may cause insufficient strength of the crack-proof pavement 40 for the construction road, or the water permeability may be reduced due to the reduction of voids formed by the paving aggregate particles. In order to generate | occur | produce, it is preferable to have a composition ratio within the said range.

In addition, the pigment is configured to improve the aesthetics of the bicycle road or to distinguish the bicycle road from the sidewalk or the roadway by making the completed bicycle road have a certain color, and the road is generally used. All packaging inorganic pigments are available, and those of appropriate color can be selected and used according to the judgment of those skilled in the art.

At this time, the composition ratio of the pigment to the total weight of the bike road crack preventing pavement 40 is preferably 0.1 to 1% by weight, if the composition ratio is less than 0.1% by weight, the composition ratio is insignificant to prevent the bike road cracks The problem that the color imparting effect of the pavement material 40 becomes weak, and when it exceeds 1% by weight, the composition ratio is excessive to reduce the compositional ratio of the paving aggregate or polyurethane binder, the construction of the crack-proof pavement for the road completed Since the problem of the intensity | strength of 40) arises, it is preferable to have a composition ratio within the said range.

In addition, the present invention, in order to improve the elastic force against the pressing force by the bicycle wheel that can be applied to the surface of the crack-proof pavement for road construction 40 completed, in place of natural silica of the aggregate, ethylene propylene rubber (EPDM, ethylene Propylene diene monomer) may be configured to include 20 to 30% by weight.

That is, ethylene propylene rubber is known as a material having excellent ozone resistance, weather resistance, aging resistance, heat resistance, cold resistance, and chemical resistance, and in the present invention, the impact resistance is improved by improving the elastic force by the excellent elongation of ethylene propylene rubber, The effect of absorbing the impact of the bicycle wheels traveling on the road can be obtained, whereby the effect of further improving the riding comfort of the cyclist can be obtained.

In addition, the ethylene propylene rubber is to ensure the elasticity and semi-elasticity of the surface of the pavement material properly when the anti-crack pavement 40 for the bicycle road according to the present invention is used as a bicycle and pedestrian combined road, the smooth running of the bicycle Of course, it is effective to ensure comfortable walking of pedestrians.

In addition, the composition ratio of ethylene propylene rubber with respect to the total weight of the anti-cracks pavement 40 for bicycle roads is composed of 20 to 30% by weight, the same as the composition ratio of natural silica with respect to the total weight of the anti-cracks pavement 40 for bicycle roads. It is possible to use a mixture of natural silica and ethylene propylene rubber in an appropriate composition ratio in the composition ratio according to the judgment of those skilled in the art.

In addition, the present invention is a pavement aggregate consisting of a mixture of steelmaking slag and natural silica (or ethylene propylene rubber), with respect to the total weight of the crack prevention pavement material 40 for bicycle roads, any of rust salt, squale site or soda fluorite It is possible to further comprise one to three percent by weight of one or more aggregates.

At this time, the rust salt, squalesite or soda fluorite is a mineral containing the silicic acid as a main component, has an effect of increasing the strength of the crack-proof pavement 40 for a bicycle road according to the present invention.

In addition, aggregates such as rust salt, squalesite or soda fluorite, which are further included in the pavement aggregate, may be obvious to use those having an average particle size similar to or smaller than that of the pavement aggregate included in the anti-cracks pavement 40 for bicycle roads. Aggregate of this size is introduced into the pores between the particles and the particles of the packaging aggregate to fill the pores and at the same time to realize the effect of allowing water to penetrate into the smaller pores formed between the aggregate particles.

In addition, the chlorite has a SiO 인 which is a basic structural unit of the silicate mineral, and the tetrahedral bonding method has a radiated tetrahedral shape in which two Si-O tetrahedra are connected to share one silicon ion. In addition, it is a green silicate mineral crystallized by monoclinic system, which is a highly developed columnar crystal, and minerals with metamorphic rock or granite undergo hydrothermal alteration and are produced as a product, resulting in glass or local gloss.

The rust salt stone according to the present invention has a physical property that is constantly broken into a flat surface form, densifying other compositions of the pavement aggregate than the general silicate mineral, and the water absorbed by the anti-cracks pavement 40 for bicycle roads is flat. It can be quickly moved through the base to be discharged to the ground (10) exhibits the effect of increasing the resistance to damage, such as long-term durability and freeze thaw and salt.

In aggregate, scolecite is a silicate and aluminate tetrahedron (such as nitrolite, a hydrated sodium aluminum silicate mineral belonging to a group of zeolites). It has a molecular structure consisting of chains bonded to the triangular vertices of), and has a fibrous form because the horizontal bonds between the chains are relatively poor, improving the permeability as the rust salt, and for road use By densifying the hydrate of the crack-proof packaging material 40 exhibits the effect of increasing the resistance to damage, such as long-term durability and freeze-thawing and salt.

In addition, the soda fluorite of the aggregate is a kind of fluorite mineral similar to the characteristics of squalesite and at the same time is a tetragonal silicate mineral. In addition, since the soda fluorite has an elongated row-shaped columnar or needle-shaped crystal form, the water permeability is improved like the rust salt, and like the squalesite, the hydrate of the anti-cracks pavement 40 for bicycle roads is precisely The long-term durability and resistance to damage, such as freezing and thawing, and salts are exerted.

In connection with the above, the aggregate according to the present invention is preferably further included in a composition ratio of 1 to 3% by weight relative to the total weight of the anti-crack pavement 40 for the bicycle road. At this time, when the aggregate is contained in less than 1 part by weight, it is difficult to improve the permeability and durability due to the aggregate and the resistance to damage such as freeze-thawing and salt damage is insignificant, and when included in excess of 3% by weight, Although the same effect improvement is excellent but the problem of inferior economy arises, it is preferable to have a composition ratio within the said range.
