On the other hand, the chemical foaming agent is used to improve the flexibility by generating fine bubbles. It contains the crystallized Hatrium Aluminum Silicate component which causes the hydration reaction. It penetrates about 20% of water and decomposes at 85 ~ 180 ℃ As a result, it is possible to improve the workability of the asphalt mixture and the aggregate coverage of the asphalt mixture even at a low temperature by inducing the foaming action on the asphalt by expanding the asphalt area.
That is, the asphalt modifying additive is used for the purpose of improving the quality of the asphalt and improving the workability. Especially, the moderate temperature additive improves the workability of the asphalt and improves the coverage of the aggregate at the middle temperature of 120 to 140 ° C.
On the other hand, PET (Polyethylene Phthalate) and PBT (Poly-Butylene-Terephthanate) have an advantage of excellent rigidity and heat resistance. Further, it has an advantage that it has a high melting point, a low water absorption rate and a low coefficient of linear expansion, and therefore is excellent in stability, excellent in impact resistance, and excellent in electrical properties and weather resistance.
However, there is a disadvantage that PET and PBT have a melting point of 220 ° C or higher and are difficult to use for an asphalt mixture below 180 ° C.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view of a method for producing an asphalt additive and an asphalt additive according to the present invention,
Fig. 2 is a view showing an application range of the asphalt additive.
The objects, particular advantages and novel features of the present invention will become more apparent from the following detailed description and examples taken in conjunction with the accompanying drawings. It should be noted that, in the present specification, the reference numerals are added to the constituent elements of the drawings, and the same constituent elements are assigned the same number as much as possible even if they are displayed on different drawings. Also, the terms first, second, etc. may be used to describe various components, but the components should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.
Hereinafter, the asphalt additive of the present invention, the method for producing the same, and the asphalt mixture and the method for producing the same will be described with reference to the accompanying drawings.
As shown in FIGS. 1 and 2, the mesophilic asphalt additive of the present invention is applied to a medium temperature asphalt mixture of 120 to 140, and can be applied to mesophilic, mesophilic modified, mesophilic, low-noise asphalt mixture and regenerated asphalt mixture.
The mesophilic asphalt additive of the present invention is produced by heating and mixing 50 to 150 parts by weight of any one material selected from among bronze asphalt and gilnonite to 220 to 300 ° C in 100 parts by weight of any one material selected from PET or PBT to prepare a base additive .
Asphalt additives for medium temperature are mainly composed of PET and PBT. They are melted at 100 ℃ and can not be ignited even at 300 ℃ so that they can be melted and used. Bron asphalt or natural asphalt ginsonite do.
PET and PBT are excellent in rigidity, heat resistance, and high melting temperature, and are excellent in resistance to plastic deformation after asphalt pavement and low in absorption coefficient and linear expansion coefficient, thereby improving the stability of the mixture.
In addition, the above-mentioned characteristics improve the weather resistance and impact resistance of the mixture, thereby enabling production of a mixture of excellent quality.
PET and PBT are melted at a high temperature. Therefore, in order to use the PET and PBT stably, bronze asphalt having high asphalt content or ginsonite as natural asphalt is used among asphalt having high ignition point.
When oil is mixed, there is a risk of fire due to a low ignition point, so there is a limit to use.
Therefore, it is very important to first melt any one of the materials of PET and PBT and the material of bronze asphalt and gilsonite, and then mix it with other additives.
As described above, the content of bronze asphalt and gilsonite is controlled within the range of 50 to 150 parts by weight. When the content is less than 50 parts by weight, the flowability is decreased. When the content is more than 150 parts by weight, It is difficult to maintain the target quality because the use amount of PET and PBT decreases.
As described above, although the melting temperature is lowered by mixing at the above mixing ratio, it is preferable to add process oil and rosin (rosin) because the viscosity is high and it is difficult to handle. .
The process oil serves to increase the viscosity. When the addition amount is less than 10 parts by weight, the viscosity change is not affected. When the amount is more than 100 parts by weight, the quality of the asphalt mixture can not be stabilized .
When rosin is used in an amount of less than 10 parts by weight, it is difficult to expect an effect of use. When the amount of rosin is more than 100 parts by weight, it becomes brittle due to high stiffness. Therefore, Should be used.
Hereinafter, the plant type and the melting type in the new asphalt mixture will be described first, and the plant type and the melting type in the reclaimed asphalt mixture will be described later.
For the plant input type, the high-temperature additive used in the new asphalt mixture is applied only to the modified asphalt mixture having a PG grade of 70-22, 76-22, 82-22, since the PG grade of the asphalt itself is 64-22 .
The high temperature additive used in this new asphalt mixture is prepared by mixing crushed waste tire (CRM), which can act as a modifier, with 100 parts by weight of the base additive.
Since the crushed waste tire has a critical temperature of 250 DEG C or higher, there is an advantage that it can be stably coated by heating. The pulverized waste tire is used within a particle size range of 0.074 to 2 mm, and is used by heating within a range of about 120 to 180 ° C.
The amount of the ground additive to be coated is 100 parts by weight of the base additive, and 300 to 1000 parts by weight of the pulverized waste tire powder is heated.
When the amount of the heated pulverized waste tire powder is less than 300 parts by weight, the amount of the base additive to be used is excessively large, so that the pulverized waste tire powder particles adhere to each other, resulting in a decrease in productivity. If the heated pulverized waste tire powder exceeds 1000 parts by weight, The use amount of the base additive is low, which makes the use inconvenient.
In the plant type, the moderate temperature additives used in the new asphalt mixture are applied to PG grades 64-22, 70-22, 76-22, 82-22. In the high temperature additive used for the new asphalt mixture described above, .
The warming agent may be selected from PE WAX, SASOBIT WAX and rosin, and the amount thereof is adjusted within the range of 10 to 100 parts by weight.
When the thermosetting agent is added in an amount of less than 10 parts by weight, the effect of thermosetting is deteriorated. When the thermosetting agent is added in an amount exceeding 100 parts by weight, the amount of the base additive is decreased.
If the melt type is used (the melt type is applied only to the PG grade 64-22), one or more of PE WAX, SASOBIT WAX, and rosin, which are the thickening agents, may be selected without using pulverized waste tire as a base additive 10 to 100 parts by weight, and 30 to 200 parts by weight of process oil are added to the mixture.
When the process oil is added in an amount of less than 30 parts by weight, workability is deteriorated. When it exceeds 200 parts by weight, PG grade 64-22 can not be satisfied.
The additive used in regenerated asphalt can be used for 120 to 180 ° C asphalt mixture for both high temperature and medium temperature, and can be used in both plant type and melting type. PG grades 64-22, 70-22, 76-22 .
The additives used for the regenerated asphalt (high temperature and medium temperature) are prepared by adding 100 to 1000 parts by weight of process oil, which is a softener, to the additive used in the above-mentioned new asphalt mixture.
When the process oil is used in an amount of less than 100 parts by weight, the recycled aggregate can not be softened. When the process oil is used in an amount exceeding 1000 parts by weight, the PG grade 64 is not satisfied, thereby causing plastic deformation during asphalt pavement.
As the adhesive, any one of PE WAX, SASOBIT WAX and rosin is selected and used while controlling the amount of the adhesive in the range of 10 to 100 parts by weight. If the amount of the pressure-sensitive adhesive is less than 10 parts by weight, the effect of using the pressure-sensitive adhesive is hardly expected. If the amount is more than 100 parts by weight, the rigidity is excessively increased and the effect of the process oil is deteriorated.
On the other hand, SBS, LDPE, HDPE, etc. can be added for the workability and the PG grade control, without discriminating between the new asphalt, regenerated asphalt, high temperature and low temperature.
The asphalt mixture using the asphalt additive of the present invention and the method for producing the same are manufactured by mixing predetermined aggregate, filler and asphalt on the basis of the above-described asphalt additive and the production method thereof. The description of Examples 1 to 4 will be omitted.
