PROBLEM TO BE SOLVED: To enhance the durability of a pavement around a structure such as a supporting frame by improving adhesion between a pavement material and the structure such as the supporting frame. SOLUTION: The technique for preventing the peeling of the pavement around the structure such as the manhole cover supporting frame comprises a first step of installing a formwork 18 outside the structure 11 to be encircled with a space 19 being kept as required and filling a special pavement material 23 using thin aggregates into at least the surface layer, appearing on a road, of the space 19 between the structure 11 and the formwork 18 to construct a peeling preventing portion 24 and a second step of filling a general pavement material 26 around the peeling preventing portion 24 to construct a general road surface 27.
