PROBLEM TO BE SOLVED: To provide a method for constructing a porous elastic pavement, by which frictional performance is imparted only to the required section of a paved-road surface and a cost can be reduced by preventing the dispersion of frictional performance while preventing the deterioration of performance. SOLUTION: An elastic paving layer 2 in which rubber chips 3 are bound by binders 4 is formed on a road bedrock 1 in a specified thickness, and the surface of the elastic paving layer 2 is finished. Aggregate 5 for a friction (dried sand is used in the working form but metal powder, a mineral matter, a short-fibrous material or the like can also be used) having a specified size is scattered quantitatively in an extent that a surface layer 2a is covered in the case of the uncured state of the binders 4 and aggregate 5 for the friction is fixed onto the surface layer 2a of the elastic paving layer 2 together with the curing of the binders 4.
