[0028] The present invention will be further described in detail below with reference to the drawings and specific embodiments:
[0029] Such as figure 1 with figure 2 As shown, a separate asphalt mixture rutting test piece forming mold includes an upper separation groove 1, a lower separation groove 2, a heat insulation handle 3, a fixed shaft socket 4, a fixed shaft 5, a temperature sensor 6, a dynamic temperature display 7 , Anti-sticking coating 8, high temperature thermal insulation coating 9, sliding lock device 10. The sliding locking device 10 includes a locking groove 11, a sliding locking plug 12 and a locking hole 13. Among them, the upper separation groove and the lower separation groove are both a dustpan-like structure composed of three side plates and a bottom plate welded together, which can form an asphalt mixture rutting test piece forming mold with an upper opening after being connected. The upper separation groove 1 and the lower separation groove 2 are conn...
