The upper surface layer is increased from both edges to the central part, An upper surface layer forming step S3 forming a surface layer; Road pavement is completed in the curing step S4 in which road paved roads are cured in a usual manner, and the road packed with the pavement composition of the loamy road is environment-friendly, has excellent durability and strength, and has no shrinkage property.

Generally, roads are packed with road pavement materials such as asphalt, cement concrete or elastic packing materials for roads, parks, promenades, and roads in apartment buildings. These asphalt or cement concrete have a relatively high strength and are easy to construct Recently, yellow clay packaging materials containing yellow clay have been developed.

Therefore, in the prior art disclosed for forming a pavement by using loess as a raw material with the object of providing an environmentally friendly functional package, Korean Patent No. 408594 discloses a loess road packaging material and a manufacturing method thereof, As a means for providing a road packaging material capable of retaining the loess color with high compression strength, a high purity loess powder which is uniformly and finely processed in the loess particles is mixed with the cement, and the cement and the optimum strength can be maintained And the addition of iron oxide, which is an inorganic pigment, in order to complement the graying of the yellow clay packaging material due to the increase in the amount of the cement admixture has been disclosed. In addition, Patent Publication No. 0924133 discloses that 15 to 50 wt% of loess powder, 10 to 40 wt% of lime powder, 20 to 50% by weight of water particles and 5 to 25% by weight of a water soluble soil solidifying agent to prepare an ocher mortar; Adding 10 to 30% by weight of the loess mortar to 70 to 90% by weight of the main material which is natural soil or marathon, And a wet non-beam step in which water is added to the dry bean-beam composition obtained in the dry bean-bead so that the slump value is 7 to 10 cm, and the mixture is stirred, is disclosed.

However, road pavement materials such as conventional asphalt, cement concrete, and elastic packaging materials can not absorb solar radiation and transfer to the atmosphere, thereby increasing the atmospheric temperature. In the case of parks and walkways, In particular, cement concrete pavement has high shrinkage and swelling power, so there is a disadvantage that shrinkage joint spacing is 2 ~ 3m as standard, expansion joint spacing is 30m as standard, and elastic packaging material is weak in durability There is a problem that it gets out quickly.

In addition, when the road is packed with a conventional ocher packing material, it is possible to radiate far-infrared rays to provide a number of beneficial effects to the human body. However, in order to give a weak point and a certain strength, There is a problem that the utility of the yellow clay is deteriorated by mixing a solidifying agent and various additives.

In order to solve such a problem in some loess compositions and loess pavement, solidifying agent components developed by a method of baking oyster shells and the like without using any cement are used, but their use is also poor in economic efficiency, , Acid resistance and the like, and cracks.

Therefore, road pavement containing loess is excellent in strength and durability of the pavement surface. In the process of penetration of moisture on the pavement surface during rainfall, water is absorbed directly to lower the road surface temperature, Providing a beautiful road packing method that does not emit harmful substances due to adsorption of harmful substances and does not emit harmful substances, prevents deterioration due to packing due to a large water content, and can express various colors and patterns as well as natural surfaces It can be said that it is required.

The present invention according to the present invention will first explain a pavement composition having no shrinkage property and a pavement pavement method using the pavement composition. First, the pavement composition will be explained first.

First, the calcined loess and the calcined clay are applied to the domestic calcined loess and the calcined clay, and the chemical composition of the calcined loess is shown in Table 1 below.

ingredient SiO ₂ Al ₂ O ₃ Fe ₂ O ₃ MgO CaO F content(%) 60.98 25.02 6.7 1.06 0.14 0.79 ingredient Na ₂ O K ₂ O P ₂ O ₅ MnO Rh ₂ O ₂ Other content(%) 0.84 3.17 0.1 0.12 0.36 0.72

On the other hand, the molecular structure of the calcined loess is a multi-layer structure which is a honeycomb structure type and provides a porous storage space, and has a function of controlling moisture and adsorbing pollutants in the space. The far-infrared emissivity of the loess is close to 90% In addition, the yellow loess contains a large amount of minerals necessary for the metabolism of the human body, and the properties of the loess are excellent in adsorption and biodegradability, It has been known that it emits anion in addition to the far-infrared radiation function, has an excellent deodorizing effect, and prevents the occurrence of fungi and harmful bacteria. Such a characteristic of the loess soil component is that it is packed And the far infrared rays are emitted from the road to provide benefits to the human body, The calcined yellow loess or calcined clay has a particle size of 0.02 to 2 mm in the calcined loess or calcined clay.

The aggregate was crushed aggregate suitable for KS F 2507, 2508. The aggregate particle size distribution passed through 90% to 100% in 13 mm sieve, 15% in 5 mm sieve, and 5% in 2.5 mm sieve .

As for the particle size distribution of zeolite, the zeolite passes through 90 to 100% of 10 mm sieve, passes 70 to 80% of 5 mm sieve, and almost remains in 0.08 mm sieve. The chemical composition of this zeolite is shown in the following table 2].

On the other hand, zeolites are collectively referred to as minerals which are aluminum silicate hydrates of alkali and alkaline earth metals. These zeolites are ion exchangeable. Since zeolites contain exchangeable cations in the crystal structure, they are freely exchanged with other cations. Due to its nature, zeolite can adsorb a large amount of water and selectively adsorbs unsaturated hydrocarbons or polar substances selectively by the action of cations capable of adsorbing other particulate matter in the crystal structure, and the removal efficiency of nitrogen and phosphorus There is an economical biological effect that effectively treats ammonia nitrogen while being high.

The Portland cement is a type 1 ordinary Portland cement. The chemical composition and mineral composition of Portland cement of the domestic company applied to the present invention are shown in [Table 5] and [Table 6], respectively.

On the other hand, Portland cement can be replaced by fly ash cement.

And alumina cement uses alumina cement containing 45 ~ 55% of alumina component. It mainly uses domestic company products with alumina content of 50% or more, and chemical composition and mineral composition of alumina cement Are shown in [Table 5] and [Table 6], respectively.

ingredient CA C ₂ AS CT C ₄ AF CA ₂ content(%) 72 20 5 3 -

On the other hand, alumina cement belongs to alumina limestone cement as alumina-rich cement, and as shown in Table 5 and Table 6, the composition range of alumina cement is quite wide, Since the curing agent of alumina cement does not release the alkali unlike the silicate cement, the anticorrosive protection power of the reinforcing bar can not be expected, so that it is applied to the road packaging not containing reinforcing bars, and it is eco-friendly.

The chemical composition for anhydrous gypsum is shown in Table 7.

ingredient CaO SO ₃ Fe Ti K Blain (cm ² / g) content(%) 36.05 62.21 2.96 0.36 1.0 5000

On the other hand, anhydrous gypsum is an orthorhombic mineral called gypsum, which is obtained by baking a calcium sulfate salt having no crystal number and a crystal gypsum at a high temperature of 500 ° C. or higher. In an appropriate combination with alumina cement, High strength and no shrinkage property.

In addition, the composition of the loess road roadway packaging material includes a admixture such as a water reducing agent (preferably using a high performance water reducing agent), a defoaming agent, a retarding agent and a separation preventing agent, and the characteristics and blending amount of each admixture (1 to 5 parts by weight of baked loess or calcined clay The amount of each admixture to be added) is shown in Table 8. [Table 8]

Admixture
characteristic usage
(Parts by weight based on 1 to 5 weight parts of calcined yellow loess or calcined clay) Water reducing agent Polycarboxylate 0.05 Defoamer Fatty acid 0.1 Retarder Tartaric acid 0.11 Separation inhibitor Starch 0.005

40 to 60 parts by weight of aggregate, 20 to 40 parts by weight of zeolite, 7 to 21 parts by weight of Portland cement or flyash cement, 3 to 7 parts by weight of alumina cement, 1 to 5 parts by weight of anhydrous gypsum or calcined clay, 3 to 7 parts by weight of a water reducing agent, 0.05 parts by weight of a water reducing agent, 0.1 parts by weight of a defoaming agent, 0.11 part by weight of a retarding agent and 0.005 parts by weight of a detackifying agent.

In order to test the characteristics of such a loess pavement composition, nine examples were made for the remaining combinations except for the admixture (water reducing agent, antifoaming agent, retarding agent, anti-segregation agent), and according to these examples, alumina cement and anhydrous gypsum The compression ratios and the expansion changes (length changes) were measured according to the compounding ratios. The blending ratios according to each of the nine examples are shown in [Table 9] and [Table 10]. For 100 parts by weight of the composition according to each example And 16 parts by weight of water to prepare a packaging material for experiments.

The compressive strength and the rate of change of length of the packaging material for experiment according to the above-mentioned nine examples were tested. First, the compressive strength of the packing material for the experiment was examined. The specimens prepared according to each example were 50 mm x 50 mm x The specimens were cured in a constant-temperature water bath after demineralization after 1 day's humidity curing. The compressive strength test was carried out for 1 day after the specimen was manufactured according to the KS standard (KS L 5105: 2007 compressive strength test method of hardened cement mortar) , 3 days, 7 days, and 28 days, and the compressive strength results according to each example are shown in Table 11 below.

division Compressive strength (MPa) 1 day 3 days 7 days 28th Example 1 29 crack crack crack Example 2 28 44 45 47 Example 3 28 36 39 45 Example 4 29 35 40 43 Example 5 27 34 34 42 Example 6 26 31 33 43 Example 7 24 29 31 40 Example 8 24 28 29 39 Example 9 21 27 32 39

As shown in Table 11, the compressive strength at the initial age was high when the anhydrous gypsum content was higher than the alumina cement content, and the highest was 29 MPa in the road packing material specimens according to Examples 1 and 4 . The compressive strength after 1 day was higher as the anhydrous gypsum ratio was increased. However, the test specimens according to Example 1 were excluded from the compressive strength test because the expansion crack occurred after 1 day of age.

Compressive strengths of 21 MPa or more, which is the quality standard for construction materials for bicycle roads and parking lots, were shown on the 1st day of the year in all formulation examples. Examples 2, 3, 4, 5, The experimental packings according to Examples 6, 7 and 7 showed excellent compressive strength of 40 MPa or more.

Next, in order to grasp the non-shrinkage characteristics, it is required to perform the expansion rate test in the KS standard. However, since the shrinkage characteristics are difficult to understand by the expansion rate test, The length change ratio was substituted for this, and the length of the test specimen was 25 mm x 20 mm as specified in KS L 5107 (Cement Autoclave Expansion Test Method) as the experimental road packing material according to the nine examples described in [Table 9] and [Table 10] The sample was cured at 25 ℃ × 285㎜ size for 1 day after demoulding the specimens and cured at constant temperature and humidity condition (temperature 20 ℃, humidity 65%) for 27 days. According to KS L 5107 The experiment was carried out at 6 hours, 9 hours, 12 hours, 24 hours at the ages and then once a day at the ages. The rate of change of length according to the embodiment in the standard condition (temperature 20 ° C., humidity 65% The results are shown in the following image [01].

[Image 01]

As shown in the above image [01], in the case of the example in which anhydrous gypsum is mixed with more than half of the alumina cement, although the phenomenon of gradual shrinkage after the expansion progresses in the early stage appears, It can be seen that the initial expansion can occur when the anhydrite content is higher than that of the alumina cement (at least 50%) under the standard conditions of the test.

In addition, [Image 01] shows that the rate of change of length varies greatly from 8 to 8 days in all formulations, but the change width decreases significantly after 8 days of age. This is due to the fact that etrinzite (anhydrous gypsum) And the shrinkage of shrinkage occurred mostly within 8 days of age.

The maximum length change rate of the packing material specimens for experimental use according to Example 1 in which the expansion cracks occurred at the 2nd day of the aging was about 0.1% in the compressive strength test specimens. In the case of the experimental packing material specimen according to Example 1, Cracking occurred in the cured compressive strength specimens. However, since expansion cracks did not occur in the specimens with varying lengths, it was expected that the amount of expansion during water curing would be larger. Therefore, in practice, the cement of portland cement, alumina cement, The packing material specimen for experiment according to Example 3 exhibits no shrinkage, that is, it shrinks after the initial expansion, so that the length becomes the origin I can confirm that I will return.

Therefore, it is difficult to secure a sufficient working time without addition of a retarding agent because of the blending characteristics. Therefore, in order to secure more than 60 minutes of KS standard, a retarding agent is added to all formulations, In addition, in order to improve the properties of the road pavement material, admixtures such as a water reducing agent (preferably using a high-performance water reducing agent), an antifoaming agent, and an anti-segregation agent are further included.

For reference, the reason that the higher the alumina cement ratio is, the later the termination occurs, the hydration reaction of the alumina cement is made by the following reaction formula.

3CA + 12H ₂ O → (CAH ₁₀ , C ₂ AH ₈ , C ₄ AH ₁₃ ) → C ₃ AH ₆ + 4Al (OH) ₃

In the above equation, CaO is needed more than Al ₂ O _{3 for the} initial hydrate, so the content of anhydrous gypsum (CaSO ₄ ) decreases as the ratio of alumina cement increases. Therefore, the supply of CaO is decreased and the reaction of alumina cement is relatively active It is considered that the termination is delayed.

Such a loess road pavement composition is applied to a walkway, a walkway, a bicycle road, a village road, a parking lot, etc., and a road pavement method using the loess road pavement composition will be described with reference to the flow chart of FIG. 1 and the cross- First, the step of arranging the installation site and the auxiliary layer forming step (S1) is a step of arranging the pavement for road pavement and forming an auxiliary base layer by a usual method and compiling the pavement according to the design specification of the road pavement. After the arrangement and vowing, the barrier block 10 is installed on the side of the road, and an auxiliary layer 20 according to the design specifications (typically 150 to 200 mm in thickness) is laid on the road surface.

For the reference, the auxiliary layer 20 supports and disperses the load from the surface layer and transfers it to the hearth. As the material of the auxiliary layer 20, it is appropriately applied to the specification with the film preform, cobbles, slag or the like.

Subsequently, in the lower surface layer forming step (S2), a road surface packaging material in which water is mixed with the above-mentioned yellow laver pavement composition is placed on the auxiliary substrate layer (20) to form a lower surface layer (30) Water is mixed and agitated in the packaging composition to pour the road pavement material having a slump value of about 8 into the auxiliary pavement layer 20. The road pavement material is laid to a thickness of 50 to 150 mm according to the construction design to flatten the surface.

Next, in the upper surface layer forming step (S3), a road surface packaging material in which water is mixed with the above-described yellow clay pavement composition is placed on the formed lower surface layer 30 to form an upper surface layer 40 in the shape of an upper part of the road The road pavement material having a slump value of about 8 is poured into the lower surface layer 30. The road pavement material is laid with a thickness of 50 to 100 mm according to the construction design, Like a general road structure, a gentle inclination of about 1 to 3 degrees is formed at both edges of the road, and the upper surface layer 40 is formed so as to be raised from both edges to the central part and convex at the center, Let the water fall into the edge.

Finally, the curing step S4 is a step of curing the road-packed road in a usual manner. When moisture evaporation is blocked by covering the upper part of the upper surface layer 40 with water vapor barrier film and curing for 24 hours, the road pavement is completed .

The road completed by the road pavement method is environmentally friendly, has excellent durability and strength, and has no shrink property due to the loess road pavement composition.

In other words, it is possible to adsorb moisture control function and contaminants in the porous spaces of the calcined loess and zeolite contained in the packaging composition of the loess soil used in the road pavement, while securing the permeability coefficient and releasing the far- , It is beneficial to the human body. It utilizes plasticized loess and zeolite to increase the adsorption power of unsaturated hydrocarbons, polar substances and other harmful substances, and improves the durability of the packaging material by preventing the deterioration of the packaging material by increasing the water effect of the road packaging material. It provides a pavement of ocher or various colors and harmonizes with nature and provides quick-setting, high-strength, shrink-proof roadway packaging.
