PURPOSE:To prevent the slip of wheels, and also to improve the durability of lines by forming line-material filling recessed grooves at desirous places of a pavement surface, and by filling a line material in which aggregates, synthetic resins, and colorants are mixed. CONSTITUTION:Line-material filling recessed grooves 2 are formed at desirous places of a pavement surface 1. Then, as a synthetic resin having flexibility, a thermosetting epoxy resin is made a main component, and thereto an appropriate quantity of polyamide amine as a curing agent is added, and further appropriate quantities of aggregates and colorants are mixed for manufacturing a line material 3. And the line material 3 is filled into he inside of line-material filling recessed grooves 2, and the surface thereof is finished so as to be nearly flush with that of the pavement surface 1, so that desirous lines can be formed on the pavement surface 1. |
