The invention discloses a copper mould for testing a flowing value of pavement seam filling adhesive. The copper mould comprises a first portion and a second portion which are clamped with each other, each portion comprises a vertical strip, a narrow transverse strip and a wide transverse strip are arranged on the inner side of each vertical strip at intervals, a first step is arranged on the inner side of each vertical strip and is matched with the narrow transverse strip of the other portion, a closed groove is also arranged on the inner side of each vertical strip and is matched with the wide transverse strip of the other portion, and a second step is arranged at an end of the outer side of each vertical strip. The invention further discloses a tin plate used with the copper mould and a method for testing the flowing value of the pavement seam filling adhesive by the aid of the copper mould and the tin plate. The copper mould comprises the two portions, and accordingly a test piece is not easy to damage when the copper mould is taken off. By the method, the measurement speed of a vernier caliper can be increased, measurement precision of the vernier caliper can be improved, and adverse effects due to the fact that an inner plane of an existing baking oven is not horizontal enough are eliminated.
