Abstract
Description
At present, in Korea, we use asphalt concrete aggregate as aggregate for asphalt concrete pavement. However, due to the development of indiscreet stone aggregate due to the increase in the construction amount of new road construction and road maintenance in Korea, the depletion of domestic aggregate resources and environmental pollution problem It is a fact that it is emerging.
The use of soil in asphalt concrete pavement can reduce the amount of aggregate, which is the main material, and can be formed in nature friendly packaging. The present invention has been developed so that blocks can be manufactured in advance using natural and field-obtainable soil, and can be used for parks and walkways as well as on the roads of vehicles.
The development of the technology to use blocks for soil is already outdated. Most technologies, however, simply use a certain amount of soil and contain many resins as binders. That is, the cost of the binder is increased and the rigidity is inevitably unavailable on the road where the vehicle is traveling.
Therefore, in Korea, such block floors are installed in pedestrian areas such as parks and walkways rather than general roads.
Therefore, the soil block floors using the resin can not replace the asphalt concrete pavement, meaning that it is more meaningful to simply use the soil.
In the Korean Registration Practice [20-0180876], flooring using soil is disclosed.
Asphalt block flooring containing soil should be rutted and crack resistant to be used on roads and parking lots where vehicles are driven. For this purpose, the combination of the constituent components of the mixture is important.
However, the soil in the normal state is less able to bond with asphalt. So, we have developed a method to increase the bond strength with asphalt by removing soil moisture and preliminarily mixing with soil dried with emulsion.
Asphalt block is formed on the adhesive layer by forming a base layer on the base layer, forming a fiber layer on the base layer, forming an adhesive layer on the fiber layer, forming a soil- Forming a coating layer on the upper surface of the substrate, and forming a protective layer on the coating layer,

Wherein the adhesive layer is formed by adding styrene butadiene styrene to cutback asphalt or emulsified asphalt to improve the adhesion between the fibrous layer and the soil-asphalt block to enable the fibrous layer and the soil-asphalt block to behave integrally,
The soil-asphalt block is made of soil, aggregate, asphalt, emulsion, modifier and fiber,

Soil-asphalt block flooring, which can be easily obtained from nature or on the ground, can improve rutting and crack resistance and replace general asphalt concrete pavement.
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.
Asphalt block is formed on the adhesive layer by forming a base layer on the base layer, forming a fiber layer on the base layer, forming an adhesive layer on the fiber layer, forming a soil- A coating layer is formed on the upper part, and a protective layer is formed on the coating layer.
The fibrous layer is composed of any one of geotextile, geogrid, geomembrane, geonet, and geocomposite to improve cracking and rutting resistance of the soil-asphalt block.
The adhesive layer improves adhesion between the fibrous layer and the soil-asphalt block by using styrene-butadiene styrene added to cut-back asphalt or emulsified asphalt, so that the fibrous layer and the soil-asphalt block behave as one body.
Since the fibrous layer and the soil-asphalt block are separated from each other due to dissimilar materials, an adhesive layer is formed to prevent the separation.
The soil-asphalt block is made of soil, aggregate, asphalt, emulsion, modifier and fiber.
The soil is used in a mixed state of any one or two of mud, clay, loess, marathon, weathering soil, kaolin and clay soils which can be easily obtained according to the field, And then mixed.
Natural soils generally contain natural moisture, and if they are not removed, the bonding strength between the soil and the emulsion will weaken and eventually weaken the asphalt and bond strength.
The aggregate is divided into a 4.75 mm sieve and consists of a coarse aggregate remaining in a 4.75 mm sieve, a fine aggregate passing through a 4.75 mm sieve, a filler passing through a 0.15 mm sieve and remaining at 0.075 mm or passing through a 0.075 mm sieve.
The coarse aggregate has a maximum coarse aggregate size of 10 mm or 13 mm or 19 mm in a state where any one or two or more of granular materials, limestone, and waste aggregate due to industrial by-products are mixed.
The fine aggregate may be a mixture of one or more of sand, silica sand, and aggregate powder.
The filler may be a mixture of any one or more of aggregate powder, lime, cement, and carbon black.
The weight ratio of the soil to the aggregate is 0 to 200 parts by weight of the aggregate with respect to the soil 100.
In the weight ratio of soil to aggregate, 0 part by weight of the aggregate constitutes a block without any aggregate. Also, 200 parts by weight of the aggregate indicates that the aggregate is contained twice as much as the addition amount of the soil.
The asphalt is used in an admixture of any one or more of the following grades of penetration grade: 60 to 70 or 85 to 100, viscosity grade AC-5 or AC-10, and aged residual viscosity grade AR 2000 or AR 4000.
The emulsion is used in a mixed state of any one or two of an intermediate-type or cation-type intermediate-speed-type or full-speed-condensation-type emulsified asphalt and a medium-speed curing type or a slow-curing type cutback asphalt.
When the emulsified asphalt emulsion is used, a cationic system is used when the soil is charged with an anion, and an anionic system when the soil is charged with a cation.
The modifier may be a mixture of two or more of styrene butadiene styrene, styrene butadiene rubber, styrene isoprene styrene, ground rubber, polyethylene, polypropylene, ethyl vinyl acetate, polyvinyl chloride and polyolefin, Styrene isoprene styrene, and ground rubber, and any one of polyethylene, polypropylene, ethyl vinyl acetate, polyvinyl chloride, and polyolefin.
The fibers are added in a state in which one or more of glass fiber, mineral fiber and polypropylene fiber are mixed.
The addition amount of the tanning agent varies depending on the amount of soil used.
The soil and the emulsion are mixed in advance and prepared for 1 to 2 hours.
The asphalt and the modifier are prepared in advance, and the soil mixed with the emulsion, the asphalt mixed with the modifier, and the aggregate are heated and finally mixed with the unheated fiber to form a soil-asphalt block.
The soil-asphalt block is installed in the adhesive layer.
The coating layer is applied to the upper part of the soil-asphalt block by using the same material as that of the oil and filler used in the soil-asphalt block.
The protective layer is laid down so as to be embedded in the coating layer before the coating layer is cured. The protective layer is made of the same material as the fine aggregate used in the soil-asphalt block, which passes through a 4.75 mm sieve and remains in a 2.36 mm sieve Or as a mixture of two or more of the above-mentioned soil-asphalt blocks.
