<p><P>PROBLEM TO BE SOLVED: To provide an elastic pavement which can be constructed stably with little change in viscosity due to temperature change. <P>SOLUTION: A method for forming an elastic paving body comprises a step of smoothing an elastic pavement material containing a thixotropy imparting agent, urethane prepolymer which has an isocyanate group at the terminal and which comprises a polarity solvent, and/or polyethylene glycol, a polyisocyanate compound and an active hydrogen-containing compound, and a dispersant including an amide compound with a melting point in the range of 50-145°C obtained by reaction between carboxylic acid and amine and/or polyether-ester type polyhydric carboxylic acid, on the pavement surface by using a comb-blade-like squeegee within the usable time of the elastic pavement material, a step of rolling a short- or middle-haired woven roller along the direction of work progress (woven roller rolling step), and a step of performing at least three times steps of rolling a mastic roller including a step of rolling the mastic roller at right-angle relative to the direction of travel of the woven roller and forming fine irregularity on the surface of the elastic paving body (first mastic roller rolling step). <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
