PROBLEM TO BE SOLVED: To continuously perform two kinds of construction including formation of a projected rib and application of a road sign between the projecting ribs by one construction machine at a time to improve workability and reduce cost. SOLUTION: In this construction method for the road sign with the projected rib, the formation of the projected rib having a predetermined shape and road surface application sign between the projected ribs are performed in the same process using slit type application and rotary injection type application together. While forming the projected ribs having the predetermined shape sequentially at a predetermined interval on a road surface by the slit type application, injection and application are applied on the projected ribs and the road surface between the projected ribs by the rotary injection type application so as to have predetermined thickness and width in the same manner.
