The present invention relates to a water-permeable asphalt color pavement with improved visibility as well as anti-slip properties, a manufacturing method thereof, and a method for constructing a water-permeable asphalt color paving material on roads such as roadways and bicycles using the same.

Asphalt is a residue after evaporation of most of the volatile oil components of petroleum, and maintains a highly viscous liquid or semi-solid state at high temperatures, but hardens at temperatures below room temperature.

In addition, asphalt is widely applied to building materials such as road pavement materials and waterproofing materials because it has rich plasticity, waterproofness, electrical insulation, adhesiveness, and chemical stability.

Recently, interest in road pavement that emphasizes functions such as drainage and sound absorption is increasing. In particular, color asphalt pavement with functions such as road identification, clarification of landscape and lanes, and vehicle induction according to the expansion of bus-only lanes, etc. This is getting attention. That is, in case of rain, the road pavement for road safety and environmental preservation by improving the visibility by preventing water splashing by increasing drainage on the road during rain, and reducing traffic noise is strongly socially required.

As described above, various methods for improving the low noise and drainage of the road are being devised for the stability of the pavement. Looking at the contents of patent applications as part of this method, the maximum diameter of 19 mm or less in Korean Patent Application Laid-Open No. 1999-0085214 In an asphalt mixture composed by mixing 65 to 89% of the weight ratio of coarse aggregate of 4.75 mm, 2 to 7% by weight of fine particles having a diameter of 0.075 mm or less, and 9 to 28% by weight of fine aggregate having a diameter of 0.075 to 4.75 mm, fibrous After adding 0.5 to 0.7% of the additive in weight ratio and 5 to 7% in the weight ratio of the conventional asphalt as a binder to the mixture, a drainage asphalt mixture containing vegetable fibers configured to have a porosity of 15% or more has been disclosed. However, in the case of pavement using the above-mentioned drainage asphalt mixture, the drainage function of the roadway is deteriorated due to a decrease in the porosity of the surface layer. , there was a problem that safety was not sufficiently secured due to the water film phenomenon occurring during high-speed driving, skid resistance, and diffuse reflection of the road surface.

In addition, the existing asphalt color pavement material has a large loss due to external force and is weak in weather resistance, so it has to be repaired frequently, resulting in a large amount of waste generated.

At this time, if the amount of the strength enhancer used is less than 3 parts by weight, the effect of increasing the binding force between the packaging material compositions due to its use may be insufficient, and thus the strength enhancing effect may not be effective. Therefore, it is recommended to use it within the above range.

At this time, if the amount of retroreflective material used is less than 5 parts by weight, the effect of improving the visibility of the installed color asphalt may be insignificant, and if the amount of retroreflective material used exceeds 15 parts by weight, it is excessive use and rather the mechanical properties of the installed color asphalt will be lowered. Therefore, it is recommended to use it within the above range.

Next, in the composition of the color packaging material, the anti-slip agent increases the surface friction of the color packaging material, secures the quick-drying property of the color packaging material, and prevents the formation of a film by water on the surface of the packaging material due to rainwater.
