Description

Road paving method using stone {Method of paving road using stone}

The present invention relates to a road paving method, and more particularly, to a method for paving a road using stone.

In general, asphalt concrete or cement concrete is mainly used as a road pavement material in order to withstand the repetitive load of vehicles traveling on the road.

Such asphalt concrete pavement or cement concrete pavement is economical when used for pavement of long roads, but there is a problem in that it remains damaged or worn out over time, leaving only a part in a dirty state. There is a limit to providing this.

Conventional asphalt concrete pavement has been repaired using the overlaying method with a thickness of 5 cm, but because of the disadvantage that the road is high, recently switched to the method of resurfacing after cutting. However, in the case of re-packing after cutting in this way, enormous asphalt concrete waste is generated, causing environmental problems. In addition, the maintenance of the pavement road is inevitable to block the traffic for a long time, thus causing trouble in the vehicle communication.

In addition, in the case of general stone pavement, it is mainly used for sidewalk roads and low-speed vehicle traffic roads of less than 30km / h, and various problems such as ground subsidence and stone breakage due to repeated loads during vehicle traffic occur. It was not suitable for traffic roads of more than h.

Therefore, especially in the traffic passages where major public offices and buildings in the city where many domestic and international events are held, as well as cultural assets attracting a lot of tourists, it is possible to prevent the heat island phenomenon of the city and to maintain the color and texture of the road more continuously. There is an urgent need for a pavement method of a traffic road that can be more robust, easier to maintain, and easier to maintain.

An object of the present invention is to provide a road paving method for paving the road surface of the road through which the vehicle passes using stone.

Road paving method using a stone according to an embodiment of the present invention comprises the steps of forming a base (base) on the road surface to be a road, disposing a wire mesh (Wire mesh) on the base, a dry beam including a mixed material on the base Forming and forming a first cement mortar layer, laying cement paste on the first cement mortar layer, preparing a plurality of hexahedral shaped stone roughly processed side, joint joint Placing the stones on the first cement mortar layer at regular intervals so as to form a pressure; and after the first cement mortar layer is cured, filling and curing a wet second cement mortar including a admixture on the joints. It includes.

Here, the stone is in the range of 100 to 1000 mm in width, 100 to 1000 mm in width, 50 to 500 mm in height, and the joint may have a width of 5 to 20 mm.

In addition, the admixture may include a non-contraction roughening admixture.

In addition, the first cement mortar and the second cement mortar, the volume ratio of cement, sand and the admixture may be 1: 1: 0.05 to 1: 1: 0.15, respectively.

In addition, the height of the base layer may be 100 to 200 mm, and the height of the first cement mortar layer may be 40 to 60 mm.

According to the road paving method using the stone according to the present invention,

First, it is possible to install a high-strength hexahedral shaped stone roughly processed by high-strength cement mortar, it is much more robust than conventional concrete pavement, ascon pavement.

Second, in order to secure sufficient strength, as shown by the test results, the strength of the cement mortar can be sufficiently secured by mixing the non-shrink high strength admixture.

Third, even if a part of the traffic road subsides, it is very advantageous for maintenance because it is possible to easily repair the fault by replacing only the stone of the necessary part.

Fourth, because of the use of stone can provide a road with a variety of colors and textures and a beautiful appearance than the conventional roads such as concrete pavement, asphalt concrete pavement.

Fifth, since it is possible to prevent the heat island phenomenon in the city compared to the Ascon pavement, there is an effect that can provide an environment-friendly vehicle traffic road.

Hereinafter, a road pavement method using stone according to an embodiment of the present invention will be described. 1 is a flowchart showing a road paving method using a stone according to an embodiment of the present invention, Figure 2 is a perspective view showing a stone according to an embodiment of the present invention, Figure 3 is paved by a road paving method using a stone of the present invention Joint perspective surface cross-sectional view of the old road, Figure 4 is a cross-sectional perspective view of the joint after the pavement of the road paved by the road paving method using the stone of the present invention.

1 to 4, the road paving method using the stone according to the embodiment of the present invention includes the step S10 to step S70.

First, in step S10, the base layer 100 is formed on the road surface to be a road. In general, the in-phase prevention layer 110 is installed on the road surface, the auxiliary base layer 120 is installed thereon, and the base layer 100 is installed on the auxiliary base layer 120 again.

Base layer 100 refers to a layer installed to withstand the forces transmitted from the surface layer, that is, for the purpose of structural support. The height h3 of the base layer 100 is approximately 100 to 200 mm and includes gravel, sand, and the like. Here, the surface layer means a layer on which the stone 400 to be described later is disposed.

The anti-frostbite layer 110 is used to protect the road pavement from freezing. As the non-freezing material such as gravel or sand is used, the separation phenomenon due to freezing does not occur, and the height h1 is about 200 mm. Auxiliary base layer 120 is located in the middle of the surface layer and the road surface together with the base layer 100 serves to distribute the traffic load transmitted through the surface layer and the base layer 100 to the road surface and the height (h2) is approximately 300 mm It is constructed to such a degree.

On the other hand, the road pavement method of the present invention can be used not only for the pavement to be installed from the base layer 100, but also to remove the asphalt concrete on the road surface constructed by the existing asphalt concrete method, etc. Can be. Even in this case, since the ground layer 100 is removed when the asphalt concrete is removed, the construction method is similar.

In operation S20, a lattice-shaped wire mesh 200 is disposed on the base layer 100. The wire mesh 200 serves to prevent shrinkage cracks from occurring due to evaporation of water while the cement mortar layer 300 to be described below is cured.

In step S30 is formed by laying the first non-beam beam cement cement layer 300 including the admixture on the base layer 100 on which the wire mesh 200 is disposed. Cement mortar layer 300 includes cement, sand, admixtures. Before forming the cement mortar layer 300, it is common to make vertical horizontal alignment in advance to install the stone 400 to be described later.

Here, as the admixture, non-shrink crude admixture is used, and the volume ratio of the cement, the sand and the admixture of the first cement mortar is 1: 1: 0.05 to 1: 1: 0.15, for example, 1: 1: 0.1 Used. At this time, the height h4 of the first cement mortar layer 300 is 40 to 60 mm, for example, 50 mm. Thus, the first cement mortar layer 300 is further included in the non-contraction concrete admixture can be bonded between the stone 400 and the stone 400 to be described later with a stronger strength.

The quality test results of the first cement mortar are as follows.

(Cement: sand: water: volume ratio of admixture = 100: 100: 50: 10, non-shrink high strength admixture is using JET- # 1000, test institute: test and measurement)

Serial number Exam, Inspection Event Test and inspection method unit Test result One Inflatable-7 days KS F 2562: 2004 % 0.026 2 Inflatable-28 days KS F 2562: 2004 % 0.028 3 Compressive strength-3 days KS F 2562: 2004 MPa 34.3 4 Compressive strength-7 days KS F 2562: 2004 MPa 45.5 5 Compressive Strength-28 days KS F 2562: 2004 MPa 56.9

That is, it can be seen that the first cement mortar has almost no shrinkage, and the 28-day compressive strength is 56.9 MPa, which is very solid.

Step S40 is a step of installing a cement paste (or bleeding water) in which cement and water are mixed on the first cement mortar layer 300 to make the first cement mortar viscous.

In step S50, a plurality of hexahedral shaped stones 400 are processed. Various materials may be used as the stone 400. For example, natural granite, such as Goheungseok and Sulfurite, may be used, and compressive strength of about 50 MPa or more, absorption of less than about 5%, and apparent specific gravity of about 2.5 to 2.8 g / cm 2 are used.

The stone 400 is processed by a smooth surface and various surface finishing methods after the pavement exposed to the road after the pavement, so that noise does not occur even when passing through the car, etc., providing a unique texture and durability of the stone beautiful and sturdy road surface It can be provided. The division and surface smoothing of the stone 400 is performed by various stone processing apparatuses and methods. For example, it can be performed by heat processing, burn processing, fine finishing, smoothing, black bean processing, polishing processing, etc. by a burner.

In addition, referring to Figure 2, the hexahedral side of the stone 400 is processed into an uneven surface, tapered toward the inner side with respect to the upper surface, that is, the cement mortar is easy to the side of the stone 400 by inclining inward Soak in.

Such a stone 400 is used in the range of 100 to 1000 mm in width W, 100 to 1000 mm in length L, and 50 to 500 mm in height H. When the width W or length L of the stone 400 is less than 100 mm, it is difficult to process the stone 400 by a machine, and may cause difficulty in the road paving work. On the contrary, if it exceeds 1000 mm, the size of the stone 400 is also too large and the weight is greatly increased, which may cause a difficulty in the pavement work of the road.

Next, in step S60 it is arranged to apply the pressure to the stones 400 on the first cement mortar layer 300 at regular intervals so that the joint (J) is formed (see Fig. 3). When the stone 400 is disposed on the first cement mortar layer 300, the worker wears boots and plant them one by one according to the vertical horizontal line, but taps the first cement by using a horn hammer or a rubber hammer. It is disposed so as to be partially locked to the mortar layer 300.

Step S70 is a step of filling and curing the wet second cement mortar 500 including the admixture in the joints J after the first cement mortar layer 300 is cured (see FIG. 4). In this case, the admixture includes a non-contraction roughening admixture, and the second cement mortar 500 may have a volume ratio of cement, sand, and admixture of 1: 1: 0.05 to 1: 1: 0.15, for example, 1: 1: 0.1.

After paving the road by the above procedure, road test pavement was carried out in the roadway part of the site to allow passenger cars and large trucks to run through a sufficient curing period (28 days) (maximum traveling speed 60km / h). In other words, 15ton dump truck was loaded with earth and sand (9㎥) to reciprocate, and it was tested while continuously using water truck to check the fallout of filling material during the rainy season. This was confirmed.

Thus, the present invention, unlike the pedestrian road or low-speed vehicle traffic road, since the natural stone (400) of high-strength granite material is added to the construction surface by the construction method of the existing asphalt concrete, etc. It is possible to provide, even if a portion of the traffic road subsidence is easy to maintain simply by replacing the faulty stone 400 without expensive equipment and expert personnel help maintenance is advantageous. In addition, the middle of the vehicle traffic road in the middle of the city has a great effect to provide a consistently beautiful appearance without deterioration, such as rags, can prevent the heat island phenomenon of the city can provide a more environmentally friendly vehicle traffic road.
