specific Embodiment approach 1
[0050] The asphalt mortar forming device of this embodiment, such as figure 1 As shown, its composition includes a guide rod 1, a test mold 3 and a base 4, one end of the test mold 3 is opposite to a guide rod 1, the other end is matched with the base 4, and the guide rod 1, the test mold 3 and the base 4 coaxial settings; where,
[0051] The guide rod 1 includes a hand-held block 24, a connecting rod 25 and a compacting head 26. The hand-held block 24 and the compacting head 26 are respectively coaxially connected to both ends of the connecting rod 25 to form an integrated structure, and the connecting rod 25 Outer wall sliding set solid hammer 2;
[0052] The interior of the trial mold 3 has a hollow compaction cavity 28 , two ends of the compaction cavity 28 are respectively communicated with the clamping grooves 27 , and the compaction cavity 28 and the two clamping grooves 27 are coaxially arranged.
specific Embodiment approach 2
[0053] The difference from the first embodiment is that, in the asphalt mortar molding device of this embodiment, the hand-held block 24, the connecting rod 25 and the compaction head 26 are all cylindrical and are made of metal materials; 6mm, 12mm, and the heights are 200mm, 355.5mm, and 20mm, respectively; wherein, the length of the connecting rod (25) is 374.5mm.
specific Embodiment approach 3
[0054] Different from the first or second embodiment, in the asphalt mortar molding device of this embodiment, the clamping groove 27 and the compaction cavity 28 of the trial die 3 are both cylindrical cavities; the inner diameter of the clamping groove 27 is 16 mm, and the depth is 16 mm. is 2 mm, the inner diameter of the compaction cavity 28 is 12 mm, and the depth is 56 mm; and the trial mold 3 is made of metal material.
