Abstract
The invention belongs to the field of equipment for road engineering test and in particular relates to a device and a method for testing the low-temperature flowing property of cold filling asphalt. In the prior art, a device capable of integrating operations of stirring and heating is absent in the process of preparing the cold filling asphalt in a lab. Generally a most primitive iron pan is adopted for heating, and the stirring is performed by using an iron rod. According to the mode, the heating temperature is difficultly controlled, and the temperature is easily extremely high, so that the asphalt is aged. A motor is arranged on a mixing tank; a mixing shaft is arranged in the mixing tank; one end of the mixing shaft is connected with the motor; a heating device and mixing blades are arranged on the mixing shaft. Therefore, the operation of the simultaneously stirring and heating can be performed in a test, so that an additive and the asphalt fully react, and a real test result can be obtained through the prepared cold filling asphalt. Meanwhile, the asphalt aging caused by non-uniform heating is avoided. The device is simple in structure and suitable for being used in large-area popularization and application.
Description
Technical field
The invention belongs to road engineering lab-size equipment field, be specifically related to a kind of asphalt cold repairing low temperature flowability test unit and test method thereof.
Background technology
At low temperature season, due to the temperature sensitivity of asphalt material, pitch viscosity sharply declines, and compound is difficult to construction, after repairing reluctantly, is also difficult to connect well with former road surface, and repair efficiency is often poor.Cold repairing asphalt mixture but just can address this problem.But when laboratory configuration asphalt cold repairing, lack the device that stirs and heat one.Conventionally be all to adopt the most original iron pan heating, iron staff stirs.This mode is wayward heating-up temperature not only, and easily makes excess Temperature, makes ageing of asphalt.Thereby the result to experiment exerts an influence.
Summary of the invention
The object of the invention is to overcome the shortcoming existing in above-mentioned prior art, a kind of asphalt cold repairing low temperature flowability test unit and test method thereof are provided, there is stirring and heating one, be easy to control heating-up temperature, avoid ageing of asphalt.
For achieving the above object, the present invention by the following technical solutions: comprising: stirred pot and the motor being located thereon, be provided with shaft, and one end of shaft connects motor in described stirred pot;
On described shaft, be provided with heating arrangement and stirring vane.
The tank body of described stirred pot is provided with interlayer, and inner tank wall material is carbon steel.
Described heating arrangement is heater strip.
Described heater strip power is 500w.
Described shaft is hollow steel tube, and in steel pipe, is provided with one end connection heater strip, and the other end connects the electric wire of motor.
Described stirred pot top is provided with for preventing the stirring cover of asphalt overflowing.
A test method for asphalt cold repairing low temperature flowability test unit, is characterized in that, comprises the following steps:
1) pitch is poured in stirred pot, opened heating arrangement switch, heat; After heating, actuating motor rotates stirring vane;
2) after stirring evenly, add adjuvant, then proceed to stir;
3) after having stirred, pitch is poured out, finally obtained required asphalt cold repairing.
The present invention has following beneficial effect: the prior art of comparing, and a kind of asphalt cold repairing low temperature flowability test unit is by the motor arranging on stirred pot, and the shaft wherein arranging, and one end of shaft connects motor; On shaft, be provided with heating arrangement and stirring vane.Thereby while making to test, can heat while stirring, adjuvant and pitch are fully reacted, homogeneous heating, makes the asphalt cold repairing of configuration can access comparatively real test findings, avoids because the uneven ageing of asphalt causing of heating simultaneously.This installation cost is cheap, easy to operate, and stirring is abundant, thereby has improved the quality of asphalt cold repairing.
Further, because the tank body of stirred pot is provided with interlayer, thereby can keep the mobility of pitch, other preparations when being convenient to test.
Further, because heating arrangement is heater strip, and because heater strip power is not high, thereby can prevent better that asphalt temperature is too high, and generation is aging.
A test method for asphalt cold repairing low temperature flowability test unit, owing to heating when stirring, thereby can make asphalt heating even, and then effectively prevent that asphalt high-temperature is aging, thereby can obtain experimental data accurately.
Accompanying drawing explanation
Fig. 1 is: the structural representation of asphalt cold repairing low temperature flowability test unit.
In figure: 1: stirred pot; 2: stirring vane; 3: heater strip; 4: shaft; 5: stir cover; 6: motor.
Embodiment
Below in conjunction with accompanying drawing, be described in further detail.
Referring to Fig. 1, the present invention includes: tank body is provided with interlayer, and inner tank wall the material stirred pot 1 that is carbon steel and the motor 6 being located thereon, in described stirred pot 1, be provided with shaft 4, and one end of shaft 4 connects motor 6; Heating arrangement and stirring vane 2 that the heater strip 3 that is provided with 500w on shaft 4 is.Shaft 4 is hollow steel tube, and in steel pipe, is provided with one end connection heater strip 3, and the other end connects the electric wire of motor 6.Stirred pot 1 top is provided with for preventing the stirring cover 5 of asphalt overflowing.
Test method, comprises the following steps:
1) by the inner wiped clean of stirred pot 1, open heater strip 3 switches, carry out preheating and check heater strip 3 whether working properly, whether if heater strip 3 is working properly, then it is working properly to open motor 6 check motor 6;
2) pitch is poured in stirred pot 1, opened heater strip 3 switches, heat; After heating, open motor 6 and stir;
3) after pitch stirs evenly, add pre-configured adjuvant, then proceed to stir;
4) after having stirred, pitch is poured out, residual asphalt is cleaned with gasoline, and uses rag wiped clean, and whole test operation finishes.
In this shelf jar, can heat, asphalt cold repairing can be fully mobile, and asphalt cold repairing and thinning agent or adjuvant can fully be reacted.This installation cost is cheap, easy to operate, and stirring is abundant, thereby has improved the quality of asphalt cold repairing.
Described adjuvant is asphalt modifier.
