Description

REPAIR MATERIAL FOR ASPHALTED ROAD AND METHOD OF ROAD REPAIR USING THEREOF}

The present invention relates to a road repairing material and a repair method using the same for repairing a broken part or a crack crack part of an asphalt road.

In general, automobile roads can be classified into asphalt pavement and concrete pavement, and asphalt used for asphalt pavement according to the present invention refers to residues when most of volatile oil evaporates among petroleum oil components. Mainly black or dark brown.

Asphalt is produced naturally and artificially from petroleum, and most of the asphalt currently used for pavement is petroleum asphalt. Asphalt has a high temperature and becomes a liquid state, and at low temperatures, it becomes very hard, and when paving roads, solid asphalt is heated and melted into a liquid state and aggregates such as crushed stone, sand, and stone Asphalt road is formed by mixing about 5 ~ 6% of liquid asphalt and applying it to the road and then compacting the road.

Asphalt pavement has a layered structure with a surface layer, a base layer, and an auxiliary base layer from the bottom, and among them, an asphalt mixture obtained by mixing asphalt and aggregate is used as a material constituting the surface layer of the asphalt pavement. % Is around.

Asphalt roads are partially damaged or cracked due to various factors such as lack of compaction, insufficient construction quality control when paving roads, and environmental impacts.

For example, if there is insufficient pavement cross section or unstable pavement or road surface, excessive surface spread by load of automobile, etc. causes fatigue failure phenomenon such as turtle, and if the drainage of road is not smooth, Repeated repeated expansion of the volume of water when it is frozen and shrinking of the volume of water due to seasonal changes causes the aggregates to be released from the pavement due to the decrease in aggregate strength.

As such, when a partial breakage or cracking of the pavement surface occurs, an unexpected shock is applied to the vehicle, causing a traffic accident.

Conventional methods for repairing concrete roads are usually to remove and remove broken or cracked surface layers and to fill the asphalt pavement, ie, asphalt and aggregate mixtures, and repack them in the form of compaction. The work is complicated and time consuming, such as heating process, and the hardening speed of the repacked part is slow, which blocks or restricts traffic for a long time, causing traffic jams, and resurfacing existing road surfaces. There is a problem that the durability is weak such that the repackaged portion is easily broken or detached due to the weak aggregation force of the boundary of the old material, and the maintenance cost is excessive.

The first object of the present invention devised to solve the above problems is to provide a repair material that can selectively fill a relatively narrow range of cracks, such as cracks, including partial breakage in a wide range of asphalt roads, By eliminating the heating process of asphalt and asphalt and using a fast epoxy mortar, which is a mixture of fast epoxy and silica sand, it is possible to reduce the time required for construction by accelerating the hardening speed of repairing materials and to have excellent cohesion with existing road pavement. It is to provide a water repellent for asphalt road to prevent water from seeping.

It is a second object of the present invention to provide a repair method using an asphalt road repair material to further improve the compressive strength and the adhesion strength of the road surface repaired using the repair material to further improve durability.

The present invention for achieving the first object, the surface aggregate of the asphalt is partially or intensively damaged by using the fast-hard epoxy mortar mixed epoxy and silica sand up to a volume ratio 1: 2 to 1: 4: Plastering will restore the surface. At this time, the pot life time of epoxy hard mortar mixed with epoxy and silica sand by volume ratio 1: 0, 1: 1, 1: 2, 1: 3, 1: 4, 1: 5 is 20 minutes, 60 minutes, 3 hours, 5 hours, 6 hours.

The present invention for achieving the second object, the surface aggregate of the asphalt is partially or intensively damaged by using the fast-hard epoxy mortar mixed epoxy and silica sand in a volume ratio of 1: 2 to 1: 4 on the surface of the fall off Plastering will restore the surface. At this time, the compressive strength of the fast-hard epoxy mortar in which epoxy and silica sand were mixed at a volume ratio of 1: 1, 1: 2, 1: 4, and 1: 5 was 40.9, 29, 20, and 10.4 kg / mm 2. In addition, the adhesion strength of the fast-hard epoxy mortar obtained by mixing epoxy and silica sand up to 1: 2, 1: 3, 1: 4, 1: 5 by volume is 2.05, 1.5, 1.25, 0.8 kg / mm2.

Asphalt road repairing material according to the present invention, by combining the silica sand contained in the repairing material and fast-epoxy epoxy is added to the compressive strength and adhesion of the characteristics of the epoxy, as well as the cohesion of the repairing material itself as well as the cohesion with the existing pavement In addition, since epoxy is the best waterproofing material, epoxy mortar is filled in the dropped part between the crushed stone and the crushed stone in the asphalt road even if the water penetrated into the repaired package is expanded or shrunk according to the seasonal change. Restoration of the original form has the advantage of improving the durability of the repair pavement and the existing asphalt road.

In addition, the fast-hardening epoxy contained in the repair material is quickly cured after pavement repair pavement, and the process of heating the asphalt is excluded, so that the repair construction time can be shortened, thereby minimizing the vehicle movement time limit.

In addition, according to the road repair method according to the present invention, not only water does not penetrate into the pavement by the epoxy waterproofing agent applied on the pavement, but also the surface compressive strength and adhesion strength increases, so durability is improved. Maintenance costs are reduced, resulting in lower social costs.

The present invention may be modified in various ways and may have various embodiments. Hereinafter, the present invention will be described in detail with reference to exemplary structures of the present invention. However, this is not intended to limit the present invention only to the illustrated form, and the spirit and scope of the present invention should be understood to include ordinary changes, equivalents, and substitutes of the illustrated forms.

Asphalt road repairing material according to the present invention is a repairing material for repairing broken parts in the form of crushed and concentrated form out of the partial crushed stone on the entire surface of the road.

First, as a repair material for repairing a broken part of an asphalt road, epoxy mortar made of fast-hard epoxy and silica sand is used.

Fill the damaged or cracked portion of the road by using the repair material to form a repair pavement, and to form a waterproof layer on the entire surface including the existing road and the repair pavement.

Here, the particle diameter of the silica sand forming the repair material is 20 to 100 mesh and the mixing ratio of epoxy and silica sand can be calculated by the test conditions.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 is a cross-sectional view showing a damaged portion repair form partially dropped from the entire surface of the asphalt road according to the present invention.

As shown in FIG. 1, the existing pavement 10 refers to a general asphalt road layer, and the damaged part 10a is partially broken over a relatively wide range of the existing pavement 10, and thus, the photo of FIG. It refers to the part that became shy together.

If the aggregate of the existing package (10) is partially detached and the breakage portion (10a) is formed, when the vehicle passes, the dynamic load is applied to the bottom of the breakage portion (10a), so that the impact is applied to the crushed stone alone. In addition, if the depression is applied to the vehicle, the vehicle may be damaged and the vehicle may fall or overturn in the severe case. Therefore, the repair package 20 may be filled by filling the damaged part repairing material 20a in the damaged part 10a. It is formed so that the breakage portion (10a) is the same height as the road surface of the existing package (10), so as not to further pie.

As a repair material for this, a fast epoxy mortar mixed with a fast epoxy and silica sand is used, and the material is kneaded by mixing with a drum mixer or a drill.

Silica sand is used in the fast curing epoxy mortar 20 to 100 mesh, the fast curing epoxy is 4-nonylphenol (4-nonylphenol) 5% by weight, aminoethylpiperazine (Aminoethylpiperazine) 11-19% by weight, Fast curing epoxy with 12% by weight of Fatty Acid Polyamide and 64 ~ 72% by weight of bis-polymer. It is recommended to mix epoxy and silica sand by volume ratio of 1: 2 ~ 1: 4. desirable.

2 is a cross-sectional view showing a damaged portion repaired form of the asphalt road according to the present invention while partially recessed.

If the damaged part 10a is formed in the form of the aggregate of the existing package 10 partially, the vehicle is impacted by the damaged part 10a during the passage of the vehicle, so that the vehicle is conducted when the vehicle is damaged or pitted. Alternatively, since the damaged portion 10a is filled with the damaged portion repair material 20a to form the repair package 20, the damaged portion 10a is formed by the repair package 20. Repair it in advance so that it is the same height as the road surface, so that the hole does not proceed to the defect.

The repairing material for this purpose uses a fast epoxy mortar mixed with a fast epoxy and silica sand as described above, wherein the silica sand is 20 to 100 mesh, the fast epoxy is the main component 4-nonylphenol (4 -Fast epoxy with 5% by weight of nonylphenol, 11-19% by weight of aminoethylpiperazine, 12% by weight of Fatty Acid Polyamide, and 64-72% by weight of bis-polymer. Epoxy and silica sand can be mixed in a volume ratio of 1: 2 to 1: 4.

3 is a cross-sectional view showing a repair portion of the crack of the asphalt road according to the present invention.

If damage occurs to the aggregate of the existing package 10 and a crack 10b is formed, such as a crack, the crack part is damaged due to a dynamic load applied to the crack 10b during vehicle traffic. Continued widening damage or severe development as shown in Figure 2. Therefore, the cracks 10b should be filled with the crack repairing material 20b to form the repair package 20 to repair the height of the cracks 10b to the same height as the road surface of the existing package 10.

As a repair material for this, the fast-hard epoxy mortar which mixed the above-mentioned fast-hard epoxy and silica sand is used.

As shown in FIGS. 1 to 3, when the repair package 20 is formed in each of the damaged part 10a and the crack part 10b using the epoxy mortar, the repair package 20 is excellent because the adhesion strength of the filled epoxy mortar is excellent. To prevent water from seeping into the filled part.

Coating waterproofing agent is a colorless and odorless liquid that exists as a sticky jelly like rubber when water evaporates. Examples include Chem Crete's YUFIX CCC1000 (model name), Fosroc's Sibex 031 (model name) and Padico's waterproof agent. Can be. Of course, the present invention is not limited to these materials and can be applied by selecting a waterproofing agent that exhibits the same or equivalent properties as the illustrated waterproofing agent. However, the existing waterproofing agent is only to prevent water from entering the surface, and is not the concept of restoring the damaged surface due to the dropping of the aggregate. Thus, the existing waterproofing agent has a compressive strength, adhesion strength and waterproofness while restoring the surface. There was no concept of payback.

The compounding ratio of the quick-drying epoxy mortar material which is the said water-retaining material is mixed in 20-33 volume% of quick-drying epoxy, and 80-67 volume% of silica sand of 20-100 mesh.

The blending ratio exemplified herein is an optimal numerical range in consideration of pot life, curing drying time, compressive strength, and adhesive strength of the repairing material, as in the following test example. In this case, the present invention provides fast-hardening epoxy and silica sand without heating and melting asphalt. Since the use of the mixed fast-hard epoxy mortar is the subject matter, when the repair material is prepared by applying the fast-hard epoxy and silica sand exemplified above, it should be understood that it falls within the scope of the present invention even if it is outside the range of the above-described illustrated numerical value. do.

As shown in FIGS. 1 to 3, when the fast curing epoxy mortar in which the fast curing epoxy and the silica sand are mixed to fill the breaking portions 10a and 10b is filled in the breaking portions 10a and 10b, the fast curing epoxy mortar is fast. Since it is cured in the pot life and completely cured and dried within 8 hours, it can be installed in the form of partial maintenance or total maintenance by controlling the traffic flow partly. At this time, the curing drying time depends on the temperature, so the actual asphalt floor is heated by sunlight and hardened and dried in a shorter time, so that the vehicle can pass quickly. In summer, the road can be used within two hours.

Figure 4 is a block diagram showing step by step repair process of asphalt road according to the present invention.

As described above with reference to Figures 1 to 3, the road repair method according to the present invention, the damaged part repairing material 20a or cracks in the damaged part 10a or the cracked part 10b generated in the existing pavement 10. The first step (S1) of filling the quick-drying epoxy mortar, which is the secondary repair material (20b) to form a repair package 20, the second step (S2) of plastering the repair package 20, and It proceeds to the third step (S3) to cure the repair package 20.

The fast-hard epoxy mortar for the repair package 20 is mixed using a drum mixer or a drill mixer in the field and rubbed on the floor as if using a trowel or rubber trowel. At this time, only one application of plastering to complete the work and the damaged surface repair material (20a) over the existing package 10 can be made flat surface in a very innovative and simple way that only the fine aggregate portion is filled without forming a coating layer. This is a new way to avoid partial pit pie repairs by performing a partial fine surface repair.

If the repair package 20 is cured after a certain time can be used immediately.

On the other hand, the repair package 20 is made of fast-hard epoxy and silica sand bar, epoxy helps the adhesion of the silica sand and the silica sand, and because it does not form a volume itself, the surface of the repair package 20 is made of silica sand Because of the friction, the friction is so large that it is not slippery at all. It is preferable to mix 20 to 33% by volume of epoxy resins and 80 to 67% by volume of silica sand, but the present invention is not limited to the blending ratio, and the blending ratio may be adjusted by road characteristics. .

[Example]

To prepare fast epoxy mortar, first, a mixture of 20% by volume of epoxy and 80% by volume of silica sand having a particle size of 20 to 100 mesh, and 25% by volume of epoxy epoxy and a silica sand having a particle size of 20 to 100 mesh, 75 A mixture of volume%, fast volume epoxy 33 volume% and silica sand 67 volume% of particle size 20-100 mesh were prepared and mixed in proportions, respectively, 50, 50, A 50 mm block (hereinafter, abbreviated as 'maintenance block') was molded and cured.

In addition, the asphalt used in the actual road was peeled off and the material was applied on its surface to harden.

As a comparative material, as shown to form a general asphalt road layer, 95% by weight of aggregate composed of a mixture of crushed stone and sand and 5% by weight of hot melt liquid asphalt were used to cross the actual asphalt road material of FIG. The specimens for compressive strength of FIG. 6 were prepared by cutting into blocks of 50, 50, and 50 mm in length and height (hereinafter, abbreviated as "comparator blocks").

The pot life, curing drying time, compressive strength, adhesion strength and water absorption rate of the repair material block and the comparative material block were tested by specific test equipment and conditions by the test method of each item. Derived. In this case, as shown in FIG. 7, specimens for compressive strength of fast-hard epoxy mortar were prepared for each composition ratio.

8 is a view showing the test of the adhesive strength after peeling off the asphalt road actually used to apply the fast epoxy mortar, the asphalt broken asphalt showing that the asphalt and the fast epoxy mortar does not fall even if the asphalt is broken. Show the Psalms.

(1) Compressive strength analysis

The compressive strength of the repair material block according to the present invention is 40.9, 29, 20, 10.4 N / mm2 at a volume ratio of fast-hardening epoxy: silica sand at 1: 1, 1: 2, 1: 4, and 1: 5, respectively. The compressive strength of the block (Sample 3-1 in Table 3) is 14.6 N / mm 2, whereby the repairing material according to the present invention is suitable for a section of 1: 2 to 1: 4, which has a higher compressive strength than conventional asphalt blocks. As a result, it was found that a fast hard epoxy: silica sand sand volume ratio of 1: 2 to 1: 4 is suitable for actual road application.

(2) Attachment strength analysis

The adhesive strength of the repairing material block according to the present invention is 2.05, 1.5, 1.25, 0.8 N / mm2 at a volume ratio of fast-hardening epoxy: silica sand at 1: 2, 1: 3, 1: 4, 1: 5, and concrete flooring Since the reference bond strength of the 0.8 N / ㎡ or more, through this it can be seen that the repair material according to the present invention is suitable for the section of 1: 2 ~ 1: 4 having a larger bond strength than the existing road asphalt block, Results showed that the fast-hardening epoxy: silicasand volume ratio of 1: 2 to 1: 4 is suitable for road applications.

(3) Analysis of pot life and curing drying time

The pot life of the repair material block according to the present invention is 0.33, 1, 3, 5, 6 hours at a volume ratio of fast-hardening epoxy: silica sand at 1: 0, 1: 2, 1: 3, 1: 4, and 1: 5, respectively. The hardening drying time of the repair material block according to the present invention is 7, 7, 8, 10 at a volume ratio of fast-hardening epoxy: silica sand at 1: 0, 1: 2, 1: 3, 1: 4, 1: 5, respectively. , 12 hours.

 Therefore, the first hardening time is 1 to 5 hours and the hardening drying time in which the curing is completely completed and dried is suitable for selecting a section of 7 to 10 hours. Results showed that silica sand volume ratios of 1: 2 to 1: 4 are suitable.

The curing and drying time of epoxy is very decisively affected by the temperature. Actually, the curing is carried out under the condition that asphalt is heated, so the curing and drying time is much faster in this section. In summer, it hardens to dry within 2 hours.

(4) Absorption Rate Analysis

Sample 3-1 untreated with asphalt removed on the road, and Sample 3-2 with a non-treated sample soaked in a water repellent solution, and Sample 4-1 with a non-treated sample heated and dried. After heat-drying the untreated sample, samples 4-2 prepared by immersing in a water repellent solution were prepared. After soaking each sample in water, the water absorption was determined by calculating the change in weight before and after in 100 minutes. Sample 3-1, Sample 3-2, and Sample 4-1. The water absorption of Sample 4-2 is 1.38, 1.44, 0.09, 0.14. The absorption rates of the original samples 3-1 and 3-2 or the samples dried after heating and the samples 4-1 and 4-2 showed almost similar values, but the absorption rates of the heat-dried samples were less than the original absorption rates. Can be.

As a result of analysis, the original samples, Samples 3-1 and 3-2, were used on the road and were immediately removed and measured for absorption. However, considering that the water absorption rate of the urethane waterproofing material is about 2%, the asphalt pavement itself can be said to be quite excellent waterproofing performance.

On the other hand, the samples 4-1 and 4-2 measured in the dry state after heating a sample hold | maintain the absorption rate 0.1%. This is because the open pores are all melted and connected to each other during the heating process, so there is no space for water to penetrate.

In total analysis, the water-repellent solution was treated to improve the waterproofing performance, but the water absorption rate was lower than that of ordinary asphalt pavement or urethane waterproofing materials. Heat-drying is a 24 hour heat-drying at 60 ° C. to measure the absorption rate, but since it does not actually reach 60 ° C., the absorption rate in the 0.1% range is a fairly good absorption rate.

In conclusion, it is understood that the defects of asphalt are physically aggregated or cracked and the asphalt surface is dropped, and the wetness of water has relatively little effect.

 Therefore, if you grab the aggregate on the surface that is physically falling off from the surroundings, the surface will not get wet even if the aggregate does not fall off and gets wet, so that it can be used for a long time without defects. It was.

As described above, some exemplary embodiments of the present invention have been described by way of example, but the present invention is not limited to the above-described specific embodiments, and changes in some components of the embodiments, such as mixing, etc. Various modifications can be made by those skilled in the art without departing from the gist of the present invention, and such modifications can be separately understood from the technical spirit and the prospect of the present invention.
