Material is concerned and studies, and compared with conventional pitch concrete, pouring asphalt concrete mobility is big, paves and requires height, applies
Work workability is particularly important, so special measuring instrument is needed to go to evaluate its construction workability.Document shows, Britain, day
Size, weight, the evaluation index of fluidity measuring instrument used in the area such as sheet, Taiwan are different, and operating flexibility is poor.
With reference to external pouring asphalt mixing in existing " highway steel box girder bridge floor paving technique of design and construction guide "
Expect fluidity test method, hand-made pouring asphalt mixture fluidity tester, and with the instrument test pouring type
The fluidity of asphalt.And the test bucket used in this method is iron open containers, the construction in opposing open space
Scene, heat dissipation is very fast, cannot accurately test the fluidity in its short time, and test result relative error is larger；Temperature is surveyed
Examination needs to be used alone mercurial thermometer or how much plug-in type thermometer measures for a long time, and process is cumbersome, and time-consuming, efficiency
It is low, poor accuracy；It is manually super to make, under hot environment, there is security risk；Artificial reading, relative error are also big.Therefore it needs
The basis of pouring asphalt mixture slump test as defined in " highway steel box girder bridge floor paving technique of design and construction guide "
On, a kind of novel pouring asphalt mixture fluidity tester is researched and developed, to adapt to laboratory and construction site construction quality
It needs.

Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further details in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, specific embodiment described in the utility model is a kind of novel pouring asphalt mixture flowing
Test device, including container 1, container cover 2, gravity drop hammer 3, display system, supplementary structure 4 and switch 5 are spent, the container cover 2 can
Enclosing cover is located on container 1, and the gravity drop hammer 3 is fixed on container 1 by supplementary structure 4, and the bottom of the gravity drop hammer 3 enters
In container 1, the supplementary structure 4 is connected with displacement sensor 6, and temperature sensor 7, the container 1 are fixed in the container 1
On be provided with display system and switch 5, institute's displacement sensors 6 and temperature sensor 7 are connected to display system.
In order to preferably test change in displacement, the supplementary structure 4 includes bracket 401, truss 402 and spiral button 403, institute
It states bracket 401 and is vertically set on 1 top edge of container, the bracket 401 is vertically connected with truss 402 by spiral button 403, described
Truss 402 is fixedly connected with gravity drop hammer 3.The display system includes displacement display 8 and temperature indicator 9.Displacement sensor
It is fixed on bracket by nut, is capable of the falling head of sensitive induction gravity drop hammer, and be transmitted on displacement display, it can
Different time temperature is read simply, conveniently to improve work efficiency.
In order to keep container closure more preferable, the container cover 2 is circle, and the container 1 is cylindrical body, and container cover 2 is close
