Description
Technical field
The utility model relates to a kind of bonding strength test spindle, especially a kind of asphalt and aggregate bonding strength test ingot
Son.
Background technique
Bituminous pavement is the pavement structure as made of asphalt making, and asphalt is one kind by pitch sum aggregate
Expect the mixing material of composition, in addition to being influenced by pitch and the self character that gathers materials, adhesion strength between the two is also performance
Influence performance of asphalt mixture key factor.When the adhesion strength deficiency of asphalt and aggregate, in traffic loading and Lu Biao water
Under effect, asphalt membrane will fall off from surface of aggregate, cause bituminous pavement to generate the diseases such as loose, peeling, seriously affect pitch
The pavement performance and service life on road surface.
In the method that all multipair asphalt adhesions are evaluated, the bonding strength test of asphalt and aggregate can
Intuitively, the adhesion strength between asphalt and aggregate is quantitatively reacted, is had a clear superiority relative to other evaluation methods.Pitch and collection
The bonding strength test of material is that pitch is applied on spindle, then spindle is placed on to the smooth substrate surface that gathers materials, and is used
The devices such as drawing instrument apply pulling force to spindle, when the interface of sticking of asphalt and aggregate substrate is destroyed, and records destruction
Boundary strength value.
However, due to the test result of the test influenced by asphalt membrane thickness it is significant, when asphalt membrane is thicker, failure mechanics
It will be located in the middle part of asphalt membrane, and the contact surface of non-asphaltic membrane and the substrate that gathers materials, this just makes test result that can not accurately reflect pitch
With the practical adhesion strength to gather materials.Lead to such situation occur to be primarily due to existing asphalt and aggregate bonding strength test
Spindle is unable to control asphalt membrane thickness, causes test result validity poor.
Summary of the invention
The purpose of the utility model is to provide a kind of asphalt and aggregate bonding strength test spindles.The experimental rig is set
Rationally, structure is simple for meter, easily operated, can control in asphalt and aggregate bonding strength test asphalt membrane thickness,
Realize the test to asphalt membrane and the boundary strength for the substrate that gathers materials.
The technical solution of the utility model includes: a kind of asphalt and aggregate bonding strength test spindle, includes spindle seat, spindle
The top half of seat is cylindrical structure, and it further includes having spindle cap, in spindle cap that the outer wall of cylindrical structure, which is equipped with external screw thread,
Equipped with internal screw thread, the external screw thread of the internal screw thread and cylindrical structure matches.
Asphalt and aggregate bonding strength test spindle above-mentioned, the lower half portion of the spindle seat are arc-shaped structure.
Asphalt and aggregate bonding strength test spindle above-mentioned, height and the spindle cap height phase of the cylindrical structure
Together, cylindrical structure is equipped with scale.
Asphalt and aggregate bonding strength test spindle above-mentioned, the cylindrical structure are divided into upper and lower two parts, top
It is arranged with external screw thread, lower part is arranged with scale, and the zero graduation line of scale is since the lower end surface of cylindrical structure.
The utility model has the beneficial effects that compared with prior art, the utility model by plane on control spindle cap with
The depth of the formed groove of plane on spindle seat, can quickly read depth of groove by the scale value on spindle seat, will melt
Pitch afterwards pours in a groove, and pitch is slightly compressed to the substrate surface that gathers materials downwards, can start to test after pitch is cooling.
Drawing instrument in the arc-shaped pulling force component for being caught in drawing instrument of spindle seat bottom, will be opened when test to be tested.The present apparatus can
It realizes the bonding strength test for carrying out asphalt and aggregate under the conditions of different pitches film thickness, reaches Accurate Determining asphalt and aggregate
The purpose of the adhesion strength of asphalt and aggregate under the adhesion strength of interface, or design asphalt membrane thickness.Spindle design is tested to close
Reason, structure is simple, easily operated.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
The embodiments of the present invention: a kind of asphalt and aggregate bonding strength test spindle, as illustrated in the accompanying drawings from 1 to 3, including
There is 1 spindle seat 1, the top half of the spindle seat 1 is cylindrical structure 3, and the outer wall of cylindrical structure 3 is equipped with external screw thread 4,
Further include having 1 spindle cap 2, internal screw thread 5,4 phase of external screw thread of the internal screw thread 5 and cylindrical structure 3 are equipped in the spindle cap 2
Match.
In use, spindle seat 1 and spindle cap 2 are together by a threaded connection, when the top surface of cylindrical structure 3 is not from ingot
When the threaded hole of sub- cap 2 is back-outed, the threaded hole of spindle cap 2 just will form 1 groove structure, and it is recessed then to measure this by graduated scale
Pitch after fusing is then cast in the groove again, and pitch is slightly compressed to the substrate surface that gathers materials downwards by the depth of slot
On, it can start to test after pitch is cooling.The lower half portion of spindle seat 1 is caught in the pulling force component of drawing instrument when test, is opened
Opening drawing instrument can be tested.After test structure, the pitch in groove is removed, by rotary spindle seat 1 or spindle cap 2,
The depth of i.e. changeable groove, then repeats above-mentioned step.It is repeated multiple times, it can be realized in different different pitches film thickness
The bonding strength test that asphalt and aggregate are carried out under the conditions of degree, reaches the adhesion strength of Accurate Determining asphalt and aggregate interface,
Or design the purpose of the adhesion strength of asphalt and aggregate under asphalt membrane thickness.
The lower half portion of the spindle seat 1 is arc-shaped structure 6.The structure can be convenient the arc-shaped knot of spindle seat 1
Structure 6 is caught in the pulling force component of drawing instrument, and pulling force component is similar to 1 jaw structure that can move freely opening, gathering, when
Drawing instrument is opened, and can be caught in the arc-shaped structure 6 of spindle seat 1 wherein, and after drawing instrument collapses, pulling force component can jail
Firm ground blocks arc-shaped structure 6, so that spindle seat 1 link together with drawing instrument well.
The height of the cylindrical structure 3 is identical as 2 height of spindle cap, and cylindrical structure 3 is equipped with along its short transverse and carves
Degree 7.The setting is advantageous in that, since the height of cylindrical structure 3 and the height value of spindle cap 2 are fixed and invariable, works as ingot
When the bottom surface of sub- cap 2 is concordant with the bottom surface of cylindrical structure 3, the top surface of spindle cap 2 is just flat with the top surface of cylindrical structure 3
Together, at this point, spindle cap 2 just shelters from the scale 7 in cylindrical structure 3 completely, groove is filled and led up.And work as cylindrical structure
3 when not being fully screwed into the threaded hole of spindle cap 2, by read exposed outside in cylindrical structure 3 come scale 7, that is, may know that
The depth of groove that cylindrical structure 3 and spindle cap 2 are formed be it is how many, this goes to measure there is no need to reuse graduated scale.
The cylindrical structure 3 is divided to for upper and lower two parts, and top is arranged with external screw thread 4, and lower part is arranged with scale 7, is carved
The zero graduation line of degree 7 is since the lower end surface of cylindrical structure 3.The advantages of this arrangement are as follows reading the scale for exposing outside and
Value is the depth of groove.
