Construction method of lane marker for intelligent transportation system compatible road

摘要

PROBLEM TO BE SOLVED: To increase construction speed, to simply control accuracy in construction, to realize the construction method of a lane marker at a low cost and to obtain the optimum construction method as the construction works at a long distance when magnetic nails as the lane marker are projected from a road surface or buried without projection. SOLUTION: Magnetic nails 2 are disposed onto a beltlike sheet 3 made of a synthetic resin at proper intervals, a road surface 1 is cut in a grooved shape, and the beltlike sheet 3 made of the synthetic resin is laid in the groove. Or the upper section of the sheet 3 is filled with a protective material 5 as required. The beltlike sheet 3 is laid and paved in the case of a new road. Or a precast material in which couplers for inserting the magnetic nails are buried at proper intervals is disposed on the road surface or on a roadbed before pavement, and the insides of the couplers are filled with the magnetic nails 2.
