PURPOSE: An adhesive composition is provided to be able to store and transport in a solid form at room temperature, to improve workability, and to reduce the construction hour due to the short curing time after coating. CONSTITUTION: An adhesive composition for road markers(10) comprises 30 weight% of styrene block copolymer, 10 weight% of polyolefin, 10 weight% of butyl rubber, 20 weight% of tackifier, 5 weight% of plasticizer, 15 weight% of functional additive, and 10 weight% of bitumen to the total weight of the composition. The adhesive composition is in a semi-solid or liquid state at 120 deg. C or higher, and the solid state having elasticity under 120 deg. C. The functional additive is any one or a mixture of more than two selected from talc, clay, silicon dioxide(SiO2), or calcium carbonate(CaCO3). |
