Description

Permeable concrete, thin layer paving composition, and manufacturing method color concrete

The present invention provides a variety of colors and patterns, water-permeable ascon, water-permeable concrete and general concrete by spray coating method using water-soluble spray thin pavement composition, water-permeable asphalt concrete, spray-type stencil technique and color texture pattern and equipment using them. It relates to the strengthening of surface layers in civil engineering materials and to the provision of safer sidewalks and athletic leisure activities, with a variety of color patterns, color retention and slip resistance.

Existing colored pavement top coating methods (painting, non-slip pavement, ultra-thin cement laying, etc.) are generally consistent monochromatic high pressure spray coatings, or construction methods using brushes, rollers, straws, scrapers, etc. Only method is used. This construction method prevents gaps and gaps in drainage roads and permeable functional roads, creates monotonous shapes, shapes and colors, and creates simple roughness, resulting in a low sliding resistance coefficient. I have a problem. In addition, the visibility and texture of the frequently used parts and the parts that are not frequently used are causing a problem that is significantly different.

In addition, the drying time is too slow depending on the temperature after construction, which leads to civil complaints due to the prolonged time limit for work, and also has the problem of discoloration, detachment, peeling, cracking due to heterogeneity with base or surface material due to high shrinkage during drying. have. When such a problem occurs, it is difficult to reconstruct, and even if repainted or repackaged, heterogeneity due to color and texture appears.

In addition, the pavement method that mixes aggregate and resin together is applied to vehicles with frequent aggregates or coated surfaces, and is often destroyed without walking or weathering. As a result, only the resin layer remains, resulting in a slippery road. Is often formed. In general spray coating, the coating layer is thin and peels off in a short time, so that the paint remaining on the road can fill the pores of the road or flatten the road, which is more slippery than before construction, and also causes the permeable layer to be sealed early. In addition, the existing coating materials and construction methods do not form a drainable appearance in the rain, and due to the disadvantages of the resin layer, water film phenomenon and slippage cause the bicycle driver, pedestrian and sports leisure activities to cause very serious accidents. Seriously endangers safety.

In addition, excessive use of organic solvents during construction also implies problems that are not environmentally friendly, and due to the climate, the construction is too long due to the late drying, which causes many complaints and inconveniences in the construction of busy urban roads.

The present invention is a water-soluble and two-component eco-friendly solution to solve the problem of coating that reduces the porosity of the package (permeable concrete, permeable ascon, etc.), which is not very environmentally friendly and very slippery in rainy weather and has a permeability function.

In the present invention, the aggregate is used by mixing the coarse aggregate and the fine aggregate, it is possible to use a mixture of the filling material as needed. The fine aggregate means the aggregate that passes through the 2.5mm sieve and remains in the 0.08mm sieve, and natural sand, crushed sand, etc. are not used and are not limited, but the weight loss is repeated when the aggregate stability test (KS F 2507) is repeated five times. It is preferable to use 10% or less.

The coarse aggregate refers to the aggregate remaining in the 2.5mm sieve, preferably using 8 ~ 13mm size of crushed stone, slag or crushed gravel. Coarse aggregate is not limited, but the absorption rate by KS F 2503 is 3.5% or less, the wear loss by KS F 2508 is 40% or less, the safety test loss by KS F 2507 is 12 or less for sodium sulfate, ASTM D 4791 It is preferable to use the segregation content of which is 20% or less, and the coverage area by the film peeling test by KS F 2355 is 95% or more.

The content of the fiber reinforcement is preferably used 0.1 to 0.5 parts by weight based on 100 parts by weight of the aggregate. When used in excess of 0.5 parts by weight it is not preferable because the viscosity of the composition rises so rapidly that the laying operation is not easy.

In the present invention, the styrene resin is used to prevent the desorption phenomenon of the aggregate by chemically bonding the surface of the aggregate with asphalt and to increase the durability, and a recycled product of the styrene resin may be used. Recycling of the styrene resin may be performed using pellets obtained by melt extruding expanded polystyrene (EPS) or powder milled thereto. The product form is preferred because the powder form has a shorter dissolution time than flakes or pellets. The content is preferably 0.1 to 1.0 parts by weight, more preferably 0.2 to 0.5 parts by weight with respect to 100 parts by weight of the aggregate, and when the content exceeds the above range, the viscosity of the composition rises rapidly and the manufacturing cost increases. not.

In case of scattering on the surface of coating, the shape of particles to be sprayed falls on the surface of the coating as it is, so it is applied in three-dimensional form. Does not interfere with sex In addition, the visibility can be highlighted when looking at the surface coated by the three-dimensional shape. Unlike the general coating method, since the coated portion is applied to have a three-dimensional shape, even when viewed at an angle, the visibility is very excellent, and thus, when the road pavement can be highlighted by bicycle drivers and leisure activities people.

In addition, another example of the construction method
