The invention discloses an electric power circuit fault indicator which comprises an outer shell, a wire clamping part arranged on the upper portion of the outer shell, a control circuit part with a detecting and judging function, and an indication part with a fault indicating function. The outer shell comprises a left upright column and a right upright column, and the upper portion of a shell body is in a U shape. The wire clamping part comprises a spring and wire pressing plates in a J shape. The wire pressing plates are respectively connected with mounting holes of the left upright column and the right upright column of the outer shell, can rotate relative to the left upright column and the right upright column, and respectively clamp electric power wires in V-shaped grooves of the left upright column and the right upright column from the left side and the right side. The spring is used for connecting the wire pressing plates and bolts on the upright columns. When clamping wires are mounted, the spring is in a drawing state, the spring contracts after the wire pressing plates are triggered, and the wire pressing plates tightly press the electric power wires. The electric power circuit fault indicator can solve the problems that installation and disassembly are inconvenient, fault indication is not obvious, a malfunction rate is high, and a wire clamping device of an electric power circuit is easy to damage and rust and the like in the prior art.

The invention discloses a method for detecting the activation effect of an asphalt activator. The method comprises: extracting old asphalt in waste and old asphalt mixture, smearing the old asphalt on the sawtooth surfaces of cubes and cube supports respectively to obtain a smooth old asphalt surface, Apply an appropriate amount of activator between the old asphalt interfaces and combine the cube and the cube support to make the old asphalt interface in close contact, and the activator diffuses and fuses into the old asphalt for a certain period of time at the test temperature to obtain the activator test sample; use the cohesion tester to test The cohesive force of the test samples with different fusion times; the activation effect of the asphalt activator on the old asphalt is judged by the change of the cohesive force and the change of the interface morphology of the asphalt failure after the test. The invention provides a solution for the difficult observation of the activation process of the asphalt activator in the old asphalt at normal temperature and the difficulty in evaluating the activation effect.
