Zusammenfassung:The invention discloses an electromagnetic self-healing self-collecting fixture for an asphalt mixture test piece after splitting. The fixture comprises a middle frame, rectangular through grooves areformed in the top and bottom ends of the middle frame, and upper box clamps are connected with the left and right sides of the top end of the middle frame through top end torsional springs; lower boxclamps corresponding to the upper box clamps are connected with the left and right sides of the bottom end of the middle frame through bottom end torsional springs; triggering rod through grooves areformed in the upper box clamps, and triggering rod rolling-out grooves are formed in the lower box clamps. By arranging the upper box clamps, the lower box clamps and triggering rods, broken blocks of a test piece can be automatically collected by the fixture, mass loss of an asphalt mixture is reduced when the test piece is broken and collected again, and the integrity and reduction degree of the test piece are higher; it
