To prevent scattering of coarse aggregate of the pavement surface by setting each viscosity of epoxy resin main agent and a hardening agent to a specified value or less, and spraying two-liquid epoxy resin composition having a specified value of working life or less on the drainable pavement surface by a collision mixing type spray method (RIM).
A two-liquid epoxy resin composition which is formed of an epoxy resin main agent and a hardening agent, each viscosity of which is 10 poise or less and working life of which is 30 min. or elss is sprayed on a drainable pavement surface by a collision mixing type (RIM) spray method. The two-liquid epoxy resin composition is preferably such that as an index for hardening speed, the working life at a working temperature is 30 min. or less, and the hardening to touch time at 25°C is 3 hours or less. Thus, a top coat layer formed by hardening of epoxy resin is formed on the drainable pavement surface, work efficiency is good, and scattering of coarse aggregate on the pavement surface can be prevented.
