TRAFFIC SIGN PAVING/CONSTRUCTING METHOD OF CONSTRUCTING TRAFFIC SIGN OBJECT FORMED AS LANE OR ON ROAD SIDE, AS NEW TRAFFIC SIGN PAVED LAYER BURIED IN ROAD PAVING SURFACE LAYER

摘要

PPROBLEM TO BE SOLVED: To provide a construction method of remarkably reducing the wear rate of a sign object indicating a lane and a road side, which eliminates a need of repainting work for new painting, reduces an amount of use of synthetic resin paint, and cuts a continuously increasing construction cost for a traffic sign. PSOLUTION: A traffic sign object is constructed as a traffic sign paving layer 12 having a depth equal to that of an asphalt paving surface layer portion 13. The traffic sign object paving layer 12 which is a portion different from the concrete and asphalt paving surface layer portion 13 is constructed as an independent sign object paving layer using a traffic sign paving material made by mixing a coarse aggregate and a fine aggregate used for road paving with highly viscous modified paint. The sign object paving layer is, therefore, not integral with a road surface when road improvement paving work is executed, so that the sign object paving layer is not peeled off together with the road surface as in a conventional case. This eliminates a need of sign repainting work, reduces an amount of use of a synthetic resin paint, and thus brings an extra advantageous effect of eliminating a need of paving work on the outside of an unworn road side.
