PROBLEM TO BE SOLVED: To provide a road coating method which improves the adhesion of a coated surface in addition to allowing good miscibility of a main agent and a hardening agent.SOLUTION: A method for coating a road surface with a coating material composition including a main agent comprised of a polyol resin and an amine having multiple amino groups and a hardening agent comprised of an isocyanate having multiple isocyanate groups; where, the polyol resin has an SP value of 10-13, and the isocyanate has an SP value of 10-13. The method comprises mixing the main agent and the hardening agent to a main agent (A) and hardening agent (B) volume ratio (A:B) that is within a range of 1.00:1.05 to 1.00:0.95, and then coating the road with the obtained mixture.SELECTED DRAWING: Figure 1 【課題】主剤と硬化剤の混合性が良好になると共に被塗装面との密着性も向上できる道路の塗装方法を提供する。【解決手段】ポリオール樹脂及びアミノ基を複数有するアミンを含む主剤とイソシアネート基を複数有するイソシアネートを含む硬化剤とを含む塗料組成物で道路を塗装する方法であって、前記ポリオール樹脂は、ＳＰ値が１０〜１３であり、前記イソシアネートは、ＳＰ値が１０〜１３であり、前記主剤と前記硬化剤は、主剤（Ａ）と硬化剤（Ｂ）の体積比（Ａ：Ｂ）が１．００：１．０５〜１．００：０．９５の範囲内で混合され、得られた混合物によって道路の塗装が行われることを特徴とする方法である。【選択図】図１
