Recently, usage bicycle is encouraged to reduce fuel consumption and air pollution. For this purpose, bike road constructions are actively performed. However, types of pavement used in bike roads have high construction cost and performance comparing the required capacity of bike roads. Thus, an economical pavement type for construction is necessary for the effective development. Roller compacted concrete pavement have good requirements, such as easy construction and low costs, high structural performance of hydration and internal communication aggregation on compaction for bicycle roads. However, the pool landscape surface and resistance to deicer damage cannot be applied to the construction of bicycle roads. Thus, for solving this problem used coating which may have effect of improving the landscape and environmental resistance. To examine this effect were evaluated performance of roller compacted concrete pavement on the coating.

Snow-melting system has been applied not only to roads for car traffic but also to pavement for the pedestrians safety reason in some of the developed countries such as USA and Canada based on countermeasures against Natural Disasters Act revised in 2000. Even though this system was introduced in korea in 2006 and has been partly applied to car traffic roads, there is few places that the system has been applied. Therefore, in this research a snow-melting system with a block-type to cover a pavement that efficiently transfers heat form heat rays to the top of a pavement and protects the heat rays. A quality check showed that compression and bending strength was improved approximately 5 times stronger and 7 to 10 times more absorption rate than the KS(Korea Industrial Standard) requirement. Moreover, only 10 minute was required to increase temperature above zero with a block-type snow-melting system whereas approximately 180 minute was spent with the existing system. This research is expected to contribute to environmental issues and reduce accidents on a slippery road.
