Generally, bicycle roads are constructed in various ways depending on the ground condition and surrounding conditions of the area where the roads are installed, but the surface layer constituting the road surface is generally packed with asphalt concrete or cement concrete.

For example, after foundation is laid, crushed stone aggregate or concrete is laid to form a base layer, and then asphalt concrete or cement concrete is laid on top of it to cure the surface layer. Then, the coloring was applied to the surface layer by spraying the colored epoxy on the surface layer, thereby carrying out the construction of the bicycle road packaging material.

One of the other typical construction methods is collared concrete, which has the advantage of low cost of construction. However, there is a high risk of fractures, bruises and abrasions when bicycle operators and pedestrians fall due to insufficient elasticity, And cracks are generated due to the lack of adhesion between the aggregate particles of the permeable concrete and the peeling phenomenon occurs easily due to cracking or peeling. As a result, the permeable concrete is finally destroyed, and in the winter, cracks or swelling There is a problem that the inherent functions of the bicycle road and the pedestrian road are lost.

In addition, a lot of techniques have appeared for the packaging materials used in the construction of bicycle roads. For example, in Published Patent Application No. 2002-72499, 70 to 80 parts by weight of fine aggregate or silica sand and 10 to 30 parts by weight of pulverized waste tire rubber chips Discloses a water-permeable elastic packaging material composed of a top elastic layer composed mainly of a waste urethane color rubber chip on a lower support layer as a main component in order to improve water permeability of a bicycle road, There is a problem that the environment is contaminated by a rubber chip which has been lost, and a large cost is required for maintenance and the like.

Recently, researches are being actively carried out to give various functions to bicycle roads. Korean Patent No. 10-0933733 (Jan. 21, 2010) discloses a non-slip flooring for a bicycle road and a method of construction thereof. The anti-slip flooring for bicycle roads is advantageous in durability, water resistance and slip resistance, but has a low resistance to salt and alkali, and has poor adhesion to asphalt concrete pavement and cement concrete pavement.
