Description

Technical Field The present invention relates to a waterproof ascon additive, a waterproof ascon additive, a waterproof ascon additive, a waterproof ascon additive, a waterproof ascon additive, a manufacturing method thereof,

The present invention is applied to damp-proof asphalt pavement and road-pavement thin-layer pavement which are used for cement concrete, steel plate, waterproofing of bridges, aged concrete pavement, A waterproof asphalt additive, a method for producing the waterproof asphalt additive, a method for producing the waterproof asphalt, and a method for manufacturing a waterproof asphalt.

As a method of waterproofing conventional bridges, composite waterproofing method mixed with water permeation waterproofing method, coating film waterproofing method, coating film waterproofing and sheet waterproofing, and Gus Ascon packaging method were mainly used.

The penetration waterproofing method is a method of applying permeable waterproofing agent mainly using epoxy and urethane to concrete bridges. It is a method of spraying permeable waterproofing agent on the cement concrete and penetrating permeable waterproofing agent to the surface to cut off moisture.

However, when the permeation waterproofing method is applied, when the concrete is wet, permeability of the permeable waterproofing agent deteriorates and the performance is not exhibited. Moreover, when the concrete is cracked, the waterproofing property is lowered. Particularly, when the road surface is cut to repair the waterproof layer, there is a problem that the package must be dried because it is cut while spraying water.

The coating waterproofing method is mainly applied to cement concrete bridges.

Such a waterproof coating method is a method in which a primer is sprayed on an upper part of a concrete and then a coating layer is formed by using a coating layer of an MMA system or a waterproofing agent of an asphalt system. In a sheet waterproofing method, It is a public law.

The composite type waterproofing method is developed in such a manner that a sheet waterproofing method is applied to a coating layer and a coating layer formed by using an asphalt-based waterproofing agent is covered with vinyl and an ascon is packed thereon.

However, when the moisture is present in the concrete pavement, the coating film waterproofing method is not only caused by moisture or steam but also causes defects. In addition, the soft paint film is pierced by the high temperature asphalt mixture when the asphalt is packed, And the like.

 In order to solve this problem, it is possible to pack goos asphalt on a steel plate deck or a concrete bridge with a primer layer. However, when natural asphalt or modified goose asphalt is used as goose asphalt, expensive construction cost is required , There is a disadvantage that it is difficult to control the traffic during the construction of the city center as well as the construction is difficult, and there is also a problem that the Gus Ascon is cracked when applied to a shaking bridge due to rigidity.

 In addition, there is a problem that it is necessary to use a cooker (heating mixer) as a production facility.

 Gus Ascon is a fluidized ascon, and when it is packed using it, it is packed in the state that there is no void from the packaging.

Therefore, when the road surface is wet or moisture is present, the road surface is covered with moisture by the use of the Gus Ascon. When the Gus Ascon is installed, moisture may be discharged from the entrance to the exterior, After the completion, residual moisture will not escape from the process of laying the ascon in the upper part, or in the course of compaction.

As a result, the moisture that can not escape is pushed to one side, resulting in the occurrence of parts phenomenon. In addition, when the pore is removed, a hole through which the storm can penetrate may act as a cause of the pothole, It is possible to shorten.

The problems common to the conventional waterproof layer are summarized as follows.

First, when the road surface (upper part of the cement concrete pavement) is dry, that is, when there is moisture on the road surface, the penetration water repellent is not absorbed by the road surface. In case of the coating waterproofing agent, adhesion failure occurs. The adhesive is not adhered and lifting occurs. In addition, when the ascon is installed, the component phenomenon occurs due to the heat, which may cause defects.

Second, the waterproofing method using permeable waterproofing agent, film-type waterproofing agent and goosascon is too complex to be used for waterproofing the roads in the city, traffic control time (2 ~ 5 days when applied as prescribed: spraying with penetrating waterproofing agent or primer spraying It takes a long time to control the vehicle traffic during the curing time. It takes a lot of social expenses. In order to prevent this, it is often the case that the traffic control is canceled immediately.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as adhering to the prior art already known to those skilled in the art.

2 is a view showing a road surface heater used in the present invention.

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, a waterproof asphalt additive, a waterproof ascon, and a waterproof ascon construction method using the same according to the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the waterproof ascon construction method of the present invention includes a road surface heating process, a primer spraying process, and a waterproof asbestos packaging process.

The preparatory process can be preceded by the preparation of the road surface heating process, which is the process of removing the run-out of cement concrete or removing foreign matter. In the case of the steel plate, it may be a process of removing the rust or removing the paint for protecting the steel, and in the case of repairing the road, the process of cutting the road surface may be included.

The road surface heating process is a process to remove the moisture by heating the road surface of cement concrete, asphalt concrete and steel plate, and to improve the adhesion force. The road surface is heated for 60 seconds or longer by electric coil, And heating the temperature to 50 to 150 ° C.

When applying the primer described below, spraying silica sand, or spraying the texcoat in the state of heating the road surface, moisture and the like rapidly evaporate due to heat, so that the lower surface layer can be stabilized within a short period of time.

If the road surface is heated to less than 50 캜, it is difficult to remove the moisture from the road surface. If the road surface temperature exceeds 150 캜, the road surface may be damaged.

When the primer is sprayed in a range of 0.2 to 2.0 kg per m 2, the adhesion of the primer to the upper member is lowered, and when the primer is sprayed less than 0.2 kg / m 2, , The primer spraying amount should be adjusted within a range of 0.2 to 2.0 kg per m < 2 > since excessive spraying may cause cracking of the primer.

The primer spraying process may be divided into a first primer spraying process and a second primer spraying process as needed.

As the primer, one or more of epoxy, urethane, acrylic resin and asphalt primer corresponding to the thermoplastic resin can be selected and used.

When the primer spraying process is completed, a silica sand spraying process may be performed as needed.

The silica sand spraying process may be performed simultaneously with the primer spraying process, or may be sprayed together in each process when the primer spraying process is performed twice.

The silica sand improves the adhesion of the texcoat sprayed in the texcoat spraying process described later, and prevents the texcoat from being pushed by the heat generated when the waterproof ascone is installed.

Use silkworms of 3, 4, 5, 6, 4 or 8 for spraying in the range of 1 ~ 10kg per ㎡.

When the silica sand is sprayed less than 1 kg / m 2, the silica sand spraying effect can not be expected. If the silica sand is sprayed in an amount exceeding 10 kg / m 2, the adhesion force is lowered.

The sand is spread evenly with broilers and the like, but it may be sprayed by the operator by hand if a small amount is required for the repair.

When the silica sand application process is completed, the process of spraying the texcoat is carried out as needed.

Teccoat chooses any one of cutback asphalt, emulsified asphalt and rubber emulsified asphalt to spray in the range of 0.3 to 1.2 kg per ㎡.

When the tack coat is sprayed at less than 0.3 kg / m 2, the tack coat spraying effect can not be expected. When the tack coat is sprayed in excess of 1.2 kg / m 2, It is preferable to control the temperature within the range.

When the Teccoat spraying process is completed, the waterproof asbestos packaging process is carried out.

The waterproof layer is completed when the waterproof ascon is installed on the upper part and the roller is made up, and the ascon, the modified ascon, and the SMA package are performed on the waterproof ascon to make the packaging more stable.

The waterproof ascon is manufactured to have a porosity of 2% or less, a continuous porosity of 0%, and a permeability coefficient of 1 x 10 ^-7 cm / sec or less.

This waterproof ascon is manufactured by mixing coarse aggregate, fine aggregate, asphalt, filler and waterproof ascon additive. The maximum size of coarse aggregate is 19, 13, 10, and 5 mm. AP-5 and AP-3 are used for asphalt for road pavement, and CaCo3, cement, and lime are used for asphalt.

40 to 77 parts by weight of coarse aggregate and fine aggregate are used, 3 to 8 parts by weight of filler is used, 6 to 10 parts by weight of asphalt is used, and 1 to 5 parts by weight of waterproof additive is used.

Meanwhile, the waterproof ascon additive includes the first additive and the second additive, and the process of manufacturing the first additive is as follows.

As a base additive, use at least two of silica, rubber powder (pulverized waste tire, urethane, EPDM) and calcium carbonate of 30mesh (0.67mm) or less and heat it at 80 ~ 150 ℃.

1 to 3 parts by weight of aged SBS is added to 100 parts by weight of the base additive. To aged SBS, 10 to 100 parts by weight of process oil (aroma, paraffin, naphtha type) is added to 100 parts by weight of SBS, do.

1 to 5 parts by weight of aged SBS and bronze asphalt is added and the base additive is first coated and then 1 to 10 parts by weight of calcium carbonate, cement and slaked lime of 100 meshes or less (0.15 mm) is selected, By carrying out the coating, a first additive is prepared.

The aged SBS is used as a secondary additive, and the aged SBS is prepared in the same manner as the aged SBS used in the preparation of the first additive.

The waterproof ascon additive is prepared by naturally cooling or forced cooling the temperature of the first additive to 30 ° C or less, adding 3 to 20 parts by weight of a second additive (aged SBS) to 100 parts by weight of the base additive used in the production of the first additive, ≪ / RTI >

In producing aged SBS used in the first additive, the reason for absorbing the process oil is that the SBS is well dissolved to coat the base additive such as silica, and the addition of less than 1 part by weight of aged SBS to 100 parts by weight of the base additive If the coating function is not realized and the aged SBS is added in an amount exceeding 3 parts by weight, the particles are difficult to use due to their adhesion.

The reason for using the bronze asphalt is to improve the mixing property with the asphalt used in the waterproof ascon, and when it is added less than 1 part by weight of bronze asphalt, the use effect can not be expected. When the addition amount of more than 5 parts by weight Since the aggregate particles may adhere, the amount of the bronze asphalt is preferably in the range of 1 to 5 parts by weight.

The aged SBS used as the secondary additive is added in an amount of 3 to 20 parts by weight based on 100 parts by weight of the base additive. This is used as an asphalt modifier to increase the adhesion, and the asphalt PG grade is 70-22, 76-22, The PG grade of the modified asphalt is modified to be less than 70-22, and when it is added in an amount exceeding 20 parts by weight, the PG grade of the modified asphalt becomes 82 -22, resulting in an excessive quality. Therefore, it is preferable to add them within the above-mentioned range.

On the other hand, the aggregate is heated in the dryer, the asphalt is heated in the tank, the filler and the waterproof additive are added to the room temperature, and the waterproof ascon is produced at a high temperature of 160 to 220 ° C.

The finished waterproof ascon is installed after the process of spraying the tecco, and the waterproof ascon packaging process is completed by the roller compaction.

The waterproof ascon can be packed on top of aged conventional packaging, and is also applicable for thin layer packaging where the porosity is adjusted to 2 to 4% by adjusting the particle size.

Waterproof ascon can be applied to bridge cement concrete top, road cement concrete top, asphalt concrete top, bridge top steel sheet top.

When the waterproof asbestos packaging process is completed, the above-mentioned tekcoat may be sprayed once more if necessary, and the surface asbestos packaging process may be further carried out if necessary.

The top layer asbestos packing process can be carried out by wrapping the waterproof ascon, then packing the additional waterproof ascon in order to maximize the effect of general ascon, modified ascon, SMA ascon, low noise asphalt, recycled ascon or waterproof ascon. have.
