Asphalt Pavement System A water-based pavement is a material filled with water-repellent and water-retaining functions in the pores of the baseline asphalt mixture. Examples of the repair agent include cement grout containing mineral powder having a repair function through continuous void formation, and cement grout containing an absorbent polymer having a repair function according to absorption. In addition, techniques have been studied to leave voids on the surface of the parent asphalt mixture to maintain noise reduction or drainage performance. These asphalt pavement conservative pavements are constructed in the same way as semi-deformed pavements in which cement grout is filled into an open-bed asphalt mixture.

Anti-skid packaging composition according to a preferred embodiment of the present invention is 10 to 50% by weight of polytrimethylene terephthalate (PTT) resin, 8 to 35% by weight of methyl methacrylate (methylmethacrylate; MMA) resin, filler 5 to 40 wt%, 3-25 wt% titanium oxide, 0.5-10 wt% anti-separation agent, 0.1-10 wt% dibutyltin dilaurate (DBTDL) catalyst and 0.1-10 wt% curing agent Can be. In addition, the anti-slip packaging composition according to a preferred embodiment of the present invention may further comprise 0.5 to 10% by weight of the colored pigment or white pigment.

In the anti-slip packaging composition according to a preferred embodiment of the present invention, a polytrimethylene terephthalate (PTT) resin may be used as a binder. Polytrimethylene terephthalate (PTT) resin is a polymer compound having an ester bond -CO-O- in its molecule as a main base, and is generally a compound made by condensation polymerization of a dihydric alcohol or a dihydric carboxylic acid. For example, polytrimethylene terephthalate (PTT) is a lower grade of terephthalic acid, such as terephthalic acid (TPA) or terephthalic acid dimethyl (DMT), as well as chemically similar polyethylene terephthalate (PET) or polybutylene terephthalate (PBT). Alcohol diester and trimethylene glycol (TMG) can be obtained by polymerizing in a molten state using a small amount of an organic titanium compound as a catalyst. The polytrimethylene terephthalate (PTT) has excellent properties such as mechanical properties, chemical resistance, elasticity, electrical properties and heat resistance.

Scheme 1 below is a reaction scheme showing an example of forming polytrimethylene terephthalate (PTT) by polymerizing terephthalic acid (TPA) and propanediol.

The content of the polytrimethylene terephthalate (PTT) resin is preferably about 10 to 50% by weight. If the content of the polytrimethylene terephthalate (PTT) resin is less than 10% by weight, brittleness may occur. If the content is more than 50% by weight, the ductility may be too large to cause deformation such as a rolling phenomenon.

The methyl methacrylate (MMA) resin has excellent weather resistance, which is resistant to weather and climate, such as sunlight, thereby suppressing corrosion due to external environmental changes (weather and climate change) and at the same time as a package. It penetrates and integrates to improve adhesion strength and toughness, and to improve colorability by pigments. Methyl methacrylate (MMA) resin is a colorless transparent liquid, which is prepared by oxidizing tert-butyl alcohol (TBA) prepared from C4 oil in a gaseous state to prepare methacrylic acid, followed by esterification with methanol. Can be prepared. Methyl methacrylate (MMA) resin is used in many fields because of its excellent transparency, weather resistance and colorability. Polymeric materials have different properties depending on the molecular weight, but methyl methacrylate (MMA) resins are hard and flexible, and syndiotactic structures that show a continuous regularity of the polymer chain structure when radically polymerized at low temperature It shows the characteristic that the ratio of increases. Generally, acrylic resins have a high coefficient of thermal expansion, but methyl methacrylate (MMA) resins have a very high stability. Methyl methacrylate (MMA) resins are known to have the formula CH ₂ = C (CH ₃ ) CO ₂ CH ₃ . The properties of such methyl methacrylate (MMA) resin are shown in Table 1 below.

Molecular formula C ₅ H ₈ O ₂ Molar mass 100.12 g / mol Appearance Colorless liquid Density 0.94 g / cm 3 Melting point -48 ℃ (225K) Boiling point 101 ° C (225K) Solubility in water 1.5 g / 100 ml (25 ° C) Viscosity 0.6 cP at 20 ℃

The content of the methyl methacrylate (MMA) resin is preferably about 8 to 35% by weight. If the content of the methyl methacrylate (MMA) resin is less than 8% by weight is not good workability, if the content is more than 35% by weight the viscosity is small, the workability is good but the curing time is long and the strength may be weakened.

The anti-slip packaging composition of the present invention may be incorporated with filler in order to improve the heat insulation and improve durability while reducing the heat of hydration. Hollow silica powder may be used as the filler, and calcium carbonate (CaCO ₃ ), blast furnace slag, fly ash, or a mixture thereof may also be used. Hollow silica powder is a fine granular material having a hollow inside. In particular, the inorganic hollow silica powder used as the filler in the preferred embodiment of the present invention enhances the strength, increases the resistance to freeze-thawing, increases the chemical resistance to sulfuric acid, hydrochloric acid or organic acid, as well as heat of hydration. Reducing, improving hydrothermal and durability, and having an effective characteristic for the production of concrete with high strength and high durability. Such a filler not only improves the durability of the package but also improves the load resistance, and thus, the hollow silica powder can be used to form a package that can sufficiently withstand the load and impact of a large vehicle. Hollow silica powder may be of various particle diameters, but in the preferred embodiment of the present invention, hollow silica powder having an average particle diameter of 0.1 μm or less is used. If hollow silica powder having a small particle diameter is used as described above, the heat reflectivity of the package is excellent. The hollow silica powder having an average particle diameter of 0.1 μm or less may be 90% or more in spherical shape to further improve the heat reflectivity of the package to which the anti-slip packaging composition is applied, and to form a package having excellent thermal insulation.

It is preferable that the said filler mixes 5-40 weight% with respect to an anti-slip packaging composition. When the content of the filler is less than 5% by weight, the thermal insulation effect and impact strength is low, and when the content is greater than 40% by weight, the workability and strength may be lowered without much improvement.

The titanium dioxide (TiO ₂ ) is an oxide of titanium, usually referring to titanium oxide (IV), a chemical formula of TiO ₂ , a stable rutile type at high temperature, a steep at low temperature, and a brookite stable at medium temperature. It is divided into and is used for acid-resistant, alkali-resistant paint, white pigment with strong hiding power, and the like. Titanium oxide (TiO ₂ ) is added in order to improve visibility and improve stain resistance, acid resistance or alkali resistance due to excellent light reflectivity in the infrared region. The content of the titanium oxide is preferably about 3 to 25% by weight. If the content of titanium oxide is less than 3% by weight, it is difficult to expect a satisfactory level of infrared reflection effect, and if the content exceeds 25% by weight, workability and strength may be reduced.

In addition, it may further include a colored pigment to give the color as desired by the consumer. The colored pigment is for imparting visibility or identification function, and various conventional pigments can be used, and inorganic pigments are particularly preferable. The inorganic pigment may include red iron oxide, yellow iron oxide, chromium oxide (Cr ₂ O ₃ ), purple iron oxide, black iron oxide, carbon black, or the like.

In addition, the anti-slip packaging composition according to a preferred embodiment of the present invention may use cellulose (Cellulose) as a layer separation inhibitor to suppress the separation of pigments or fillers, starch, polyvinyl alcohol (polyvinyl alcohol) in addition to the layer separation inhibitor PVA), polyacrylamide or a mixture thereof may be used. The cellulose is a polysaccharide which occupies most of the wood part as a main component of the cell wall of higher plants and is also called fibrin. The chemical formula is (C ₆ H ₁₀ O ₅ ) _n , and is one of the most organic compounds present in nature. It forms the basic structure of plant cell wall, accounts for more than 30% of all plant material, and is the main component of plant cell membrane and wood. Its chemical structure is that D-glucose is polymerized by β-1 and 4 bonds in a large number, and is connected in a chain form. It is a odorless white solid and insoluble in water. Cellulose is the largest molecular weight among polysaccharides and its molecular weight reaches tens of thousands to hundreds of thousands in its natural state. It is insoluble in water, ethanol, ether, etc., but is very resistant to alkali, but hydrolyzed in acid or copper ammonia solution to form glucose. A large amount of cellobiose is produced as a compound just before decomposition into glucose. In addition, as a result of various organic and physicochemical studies, cellulose molecules are believed to be polymers formed by dehydrogenation of many glucoses and binding into cellobiose forms. Such a bond is called β-1, 4-glucoside bond. A large number of cellulose molecules form a fiber. The minimum unit is a micelle, which is 0.05 nm in diameter and 0.6 nm or more in length. X-ray analysis revealed that micelles had a crystal structure. The connecting portion of the micelle and the micelle is an amorphous region. This crystalline region and the amorphous region determine the strength, elasticity, dyeability, and hygroscopicity of the fiber. Removing moisture from cellulose makes the amorphous region crystalline and increases its elasticity and strength. When it is immersed in water or alkali, the liquid penetrates into the amorphous region and swells.

The content of the layer separation inhibitor is preferably about 0.5 to 10% by weight. If the content of the anti-layer separation agent is less than 0.5% by weight layer separation may occur, if the content exceeds 10% by weight may increase the viscosity and workability may be reduced.

In the anti-slip packaging composition according to a preferred embodiment of the present invention, dibutyltin dilaurate is used as a catalyst, and isophorone diisocyanate is used as a curing agent.

The dibutyltin dilaurate (DBTDL) is an organometallic compound used as a curing accelerator of polytrimethylene terephthalate (PTT) resin or methyl methacrylate (MMA) resin. In general, dibutyltin dilaurate is a complex metal compound based polyurethane (PU) reaction and a hardening accelerator, and is superior to other metals in terms of safety to the human body, excellent catalytic ability and thermal stability, especially The reaction rate of urethane resins, esters, etc. is increased.

The content of dibutyltin dilaurate is preferably in the range of 0.1 to 10% by weight. When the content of dibutyltin dilaurate is less than 0.1% by weight, the reaction rate is lowered and the curing time is slow. When the content is more than 10% by weight, the curing time is faster and the workability is lowered.

The curing agent isophorone diisocyanate (IPDI) is a cycloaliphatic diisocyanate monomer that is useful in the manufacture of chemicals, reactive intermediates, and polymers. Used when making Polymer products made using isophorone diisocyanate (IPDI) exhibit high flexibility with excellent mechanical strength. In addition, while maintaining excellent wear resistance, water resistance, and gloss and physical properties over time, there is a property to produce an optically transparent polyurethane (PU) when used with a suitable polyol (Polyol). The chemical formula of isophorone diisocyanate (IPDI) is C ₁₂ H ₁₈ N ₂ O ₂ . The content of isophorone diisocyanate (IPDI) is preferably in the range of 0.1 to 10% by weight. If the content of isophorone diisocyanate is less than 0.1% by weight, the reaction rate is lowered and the curing time is slow. If the content is more than 10% by weight, the curing time is faster and the workability is lowered.

Ceramic aggregate has a characteristic that the specific surface area is 8 times or more and the porosity is 7 times or more than the steel slag which is a general anti-slip material. As the ceramic aggregate, it is preferable to use a substance having a particle diameter of 2 to 4 mm. As the ceramic aggregate, garnet aggregate, elvan aggregate and the like can be used. The use of a ceramic aggregate having a large attachment cross section has an advantage in that the adhesion is increased, thereby reducing the fall of the vehicle due to friction of the vehicle tire. The spraying amount of the ceramic aggregate is preferably sprayed 600g to 2,000g per m 2. If it exceeds 2,000g, the heat shielding effect is lowered because it can cover the entire area of the anti-slip packaging composition, and if it is less than 600g, the friction force with the vehicle tire is lowered.
