Abstract
The utility model relates to a kind of mould of vibration moulding bitumen mixture specimen.Described mould comprises rotating shaft and class semicylindrical body A and class semicylindrical body B; Described class semicylindrical body A one end is provided with annulus A, and the other end is with the first contiguous block and groove; Described class semicylindrical body B one end is provided with annulus B, and the other end is with the second contiguous block and projection; Described rotating shaft is connected class semicylindrical body A and class semicylindrical body B by the annulus A be enclosed within outside it with annulus B; The surface of contact of described first contiguous block and the second contiguous block fits, and is connected with U-shaped clamping element outside both; Described U-shaped clamping element rear end is connected with the groove on the first contiguous block by bolt, and its front end is connected with the projection on the second contiguous block by rivet.Compared with prior art, the utility model, in the process of getting test specimen, only need be turned on U-shaped clamping element, can take out test specimen by axis of rotation, uses simple, decreases the labor capacity of compaction test personnel, improve test efficiency.
Description
Technical field
The utility model belongs to Load materials testing equipment technical field, specifically, relates to a kind of mould of vibration moulding bitumen mixture specimen.
Background technology
Asphalt is the general name of the compound mixed and stirred by mineral aggregate and asphaltic binder, and it is widely used in field of road.Current indoor generally adopt the shaping bitumen mixture specimen of Marshall compaction method, scene generally adopts vibroll and pneumatic-tired rollers to roll asphalt, and different compacting modes directly affects asphalt mineral aggregate particle arrangement mode, and then affect performance of asphalt mixture.There are some researches prove, marshal piece engineering properties and on-the-spot core engineering properties correlativity poor.So there is research to point out at present, test specimen vibration formation method is compared with the actual consolidation effect of marshall compaction closer to road surface, and the actual pavement asphalt mixture compactingproperties in energy simulate working-yard, improves Asphalt Mixture Performance.
The both sides of the mould of current asphalt surface vibration compactor all use bolt to carry out connecting mold, after each compaction test completes, during the demoulding, testing crew needs all turning on the bolt of both sides, the workload of experimenter can be increased so undoubtedly, reduce test efficiency.
Summary of the invention
For solving the problems of the technologies described above, the utility model provide a kind of easy to use, be easy to operate, the mould of vibration moulding bitumen mixture specimen that test efficiency is high.
The mould of a kind of vibration moulding bitumen mixture specimen described in the utility model, described mould comprises rotating shaft 1 and class semicylindrical body A2 and class semicylindrical body B3; Described class semicylindrical body A2 one end is provided with annulus A4, and the other end is with the first contiguous block 5 and groove 6; Described class semicylindrical body B3 one end is provided with annulus B7, and the other end is with the second contiguous block 8 and protruding 9; Described rotating shaft 1 is connected class semicylindrical body A2 and class semicylindrical body B3 by the annulus A4 be enclosed within outside it with annulus B7; The surface of contact of described first contiguous block 5 and the second contiguous block 8 fits, and is connected with U-shaped clamping element 10 outside both; Described U-shaped clamping element 10 rear end is connected with the groove 6 on the first contiguous block 5 by bolt 11, and its front end is connected with the projection 9 on the second contiguous block 8 by rivet 12.
The mould of a kind of vibration moulding bitumen mixture specimen described in the utility model, the internal diameter of described class semicylindrical body A2 and class semicylindrical body B3 is 120mm, and external diameter is 140mm.
The mould of a kind of vibration moulding bitumen mixture specimen described in the utility model, described U-shaped clamping element 10 has two, lays respectively at 1/3 and 2/3 place of mold height.
The mold use step of vibration moulding bitumen mixture specimen described in the utility model: 1) the perpendicular wall place of two class semicylindrical body in its side is fitted tightly, in mould, load the asphalt needed for test, the bolt on two U-shaped clamping elements is screwed in the groove on the first contiguous block; 2) test by the specification of vibrating compacting test method; 3) after off-test, the bolt on U-shaped clamping element is back-outed from the groove the first contiguous block, allow mould rotate around the axis, take out test specimen, for test is prepared next time.
Compared with prior art, the mould of vibration moulding bitumen mixture specimen described in the utility model, in the process of getting test specimen, only need be turned on U-shaped clamping element, can take out test specimen by axis of rotation.Therefore, this mould uses simple, decreases the labor capacity of compaction test personnel, improves test efficiency.
