This study proposes to use a roller compacted concrete technique for a bike road construction with advantages of its environment-friendliness. Roller compacted concrete, a durable paving material that can carry heavy traffic loads, has been developed as a fast, economical construction method. This study aims to find an optimum mix proportions and application method for field construction. Experimental programs included laboratory tests and field constructions for mechanical performance, durability and ride-ability under difference compaction rates. Based on the observations from compressive strength tests, it is recommended that the mixes for the low cementitious materials-based roller compacted concrete pavement have the cementitious binder content greater than 250kgf/m3. In order to provide appropriate workability the water content should be at least greater than 120kgf/m3 when the binder content is greater than 250kgf/m3. When the compaction method suggested herein is applied it is strongly recommended that the low cement based roller compacted concrete pavement has its compaction ratio greater than 93%. The proposed method could provide sufficient surface roughness profile and skid resistance but was weak to de-icing chemicals.
