In addition, since a reinforcement contact unit projected out by pressing of the sidewalk block has a black asphalt color as well as the reinforcement layer, various additives are added in an upper masonry joint of the reinforcement contact unit to change the color of the masonry joint and add a reflection function to the masonry joint, so aesthetic effect is provided.

Description

A Sidewalk block installation method using a reinforcement layer,

The present invention relates to an installation method for installing a sidewalk block, in which a reinforcing layer is formed using conventional asphalt paving technology and equipment, and a sidewalk block is press-fitted into a reinforcing layer so that a sidewalk block can be firmly positioned, The color of the joint portion is changed by adding various additives to the eye portion of the line formed in the eye portion, or the aesthetic effect of the joint portion is increased by reflecting the light.

Generally, when installing a sidewalk block, a sand layer is formed at the bottom of the sidewalk block. However, when supporting the sidewalk block with only the sand layer, the position of the sidewalk block is not stable due to the flow of sand. In other words, when the joint is tightened through the joint part with the adjacent block, or when the joint part is made solid, the degree of the joint is weakened, but the sidewalk block moves together with the movement of the sand. Therefore, a pedestal is formed at the lower part of the sidewalk block to secure the sidewalk block, and the adjacent sidewalk block can be coupled through the fastening protrusion and the fastening groove between adjacent blocks. A method of combining adjoining sidewalk blocks using a coupling assistant tool is also presented. However, this approach requires additional cost and effort.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals refer to the like elements throughout.

Generally, when installing a sidewalk block, a sand layer is formed at the bottom of the sidewalk block. However, when supporting the sidewalk block with only the sand layer, the position of the sidewalk block is not stable due to the flow of sand. In other words, when the joint is tightened through the joint part with the adjacent block, or when the joint part is made solid, the degree of the joint is weakened, but the sidewalk block moves together with the movement of the sand. Therefore, a pedestal is formed at the lower part of the sidewalk block to secure the sidewalk block, and the adjacent sidewalk block can be joined by forming the fastening protrusion and the fastening groove between adjacent blocks. A method of combining adjoining sidewalk blocks using a coupling assistant tool is also presented. In other words, when the fastening protrusion and the fastening groove are formed in the block, an additional mold is required in addition to a general block mold, and additional effort is required at the time of construction. In addition, when using a pedestal or an auxiliary tool, it is obvious that additional effort is required in addition to the block manufacture.

The present invention can be said to be to securely fix the position of the sidewalk block by a relatively simple method, without any further effort mentioned above. That is, by using the general asphalt pavement technique and equipment, the position of the sidewalk block is set and its position is not changed as the asphalt reinforcement layer is cured.

The rubber modifying admixtures are effective in resistance to plastic deformation in asphalt pavement at high temperatures and plastid modifying admixtures can improve crack resistance in asphalt pavement at low temperature and room temperature, have. The modifying admixture may be used in the form of a liquid and a powder. When the modifying admixture is a liquid, it is wet-mixed with petroleum asphalt. When the modifying admixture is a powder, the modifying admixture is dry mixed with the aggregate. Or may be mixed with 100 parts by weight of the aggregate without adding a part of the aggregate.

The filler mixture may be prepared by mixing at least one of water-resistant lime and carbon black to reduce brittleness to oxidation hardening, and optionally mixing plant filler materials such as wood chips, sawdust, May also be used. The filler mixture may be mixed by dry mixing to be mixed with the aggregate, the filler mixture may be mixed with the aggregate portion, or a certain proportion may be added to 100 parts by weight of the aggregate without replacing a portion of the aggregate.
