Abstract
The utility model discloses a preparation device of a sample for an asphalt film salt corrosion test. The preparation device comprises an oven and at least one sample holding container, wherein a rotating rack driven by a motor is mounted in the oven; and each sample holding container is placed on the rotating rack. Salt water is added to an asphalt film that is formed in the preparation device uniformly to simulate actual changes of asphalt of an asphalt mixture in properties in a salt corrosion environment. With the adoption of the preparation device, salt corrosion effects on the properties of the asphalt in the asphalt mixture can be simulated scientifically, and an effective method is provided for researching the properties of the asphalt mixture in the salt corrosion environment.
Description
Technical field
The utility model relates to the preparation facilities that a kind of asphalt film salt corrosion test is used sample.
Background technology
At present, along with being on the increase of coastal highway facilities and bridge spanning the sea, the works such as coastal asphalt highway and bridge spanning the sea bridge asphalt pavement stand the erosion in the naval air environment for a long time.Be rich in Na in the naval air environment
+, Cl
-, Mg
2+, SO
4 2-, Ca
2+Plasma, the physical and chemical performance of bituminous concrete and pavement performance can produce a series of variations in the saline environment of humidity, affect the usability on coastal road surface.And less about the correlation technique research of performance of asphalt mixture under the salt erosion environment both at home and abroad, the Special Equipment that does not also have asphalt film salt corrosion test to use.
Summary of the invention
For remedying the deficiencies in the prior art, the purpose of this utility model is to provide the preparation facilities of a kind of asphalt film salt corrosion test with sample.
For realizing above-mentioned technical assignment, the utility model is taked following technical solution:
A kind of asphalt film salt corrosion test is characterized in that with the preparation facilities of sample, comprises baking oven and at least one sample container, is equipped with in the described baking oven by motor-driven turret, and described each sample container is positioned on the turret.
Described turret is provided with at least one sample container putting hole.
But adopt the analog salt erosion effect of device science of the present utility model on the impact of asphalt medium pitch performance, for the performance of asphalt mixture under the research salt erosion environment provides effective means.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of sample container.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.
Embodiment
With reference to figure 1 and Fig. 2, according to the technical solution of the utility model, the asphalt film salt corrosion test of this embodiment comprises baking oven 1 and eight Sheng sample bottles 4 with device, be equipped with in the described baking oven 1 by motor-driven turret 2, described turret 2 is provided with eight sample container putting holes 3, and the Sheng sample bottle 4 that sample is housed during test is positioned in each sample container putting hole 3.
Baking oven 1 in the embodiment device has double wall, foot is heating element, electric heating system is controlled by thermostat, can keep temperature is 160 ℃ ± 1 ℃, its inside dimension is high 381mm, wide 483mm, dark 445mm, the heat-resisting windowpane of pair of lamina is arranged on the oven door, and it is wide to be 330mm, high 220mm, can observe the oven interior test situation by this window.Baking oven should be adjusted to horizontality during work.Turret 2 is the vertical toroidal frame of 305mm, and it is comprised of two identical disks, has eight to be used for placing glass and to contain the circular hole (diameter is 65mm) of sample bottle 4 on each disk.Turret 2 is connected with motor by the axle of diameter 19mm, and the speed with 15r/min during work is rotated.Contain sample bottle 4 and made by pyroceram, high 139mm ± 1.5mm, external diameter are 64mm, and wall thickness is 2.4mm ± 0.3mm, and mouth diameters is 42mm ± 1.5mm.
Adopt device of the present utility model to make asphalt film salt corrosion test as follows with the step of sample:
(1) with gasoline or triclene clean respectively contain sample bottle 4 after, placing temperature is 105 ℃ ± 5 ℃ baking oven 1 oven dry, and in exsiccator after the cooling numbering claim its quality (m
0), accurately to 1mg.
(2) respectively in the Sheng sample bottle 4 of 8 known quality implantation quality be the pitch sample of 35g ± 0.5g, then put into and take by weighing quality (m after exsiccator is cooled to room temperature
1), accurately to 1mg.
(3) with baking oven 1 adjusting level, and be no less than 3h 160 ℃ ± 1 ℃ lower preheating, make the abundant homogeneous heating of air in the case.Regulate temperature controller, after each was contained sample bottle 4 and packs on the turret 2, the temperature of baking oven should reach 160 ℃ ± 1 ℃ with interior at 10min.
(4) under 160 ℃ ± 1 ℃, turret 2 makes a bottle wall be stained with pitch with 15r/min speed rotation 10min.
(5) the Sheng sample bottle 4 that the bottle wall is stained with pitch takes out from baking oven 1, is cooled to normal temperature in exsiccator, then to wherein respectively topped up with water (contrast test) or salt solusion, 20 ℃ of environment lower seals one month.
(6) water or salt solusion of each being contained in sample bottle 4 are outwelled, and will contain the sample bottle be dried to constant weight in exsiccator.
(7) the Sheng sample bottle 4 of drying is put back in the baking oven, then heating 10-15min pours out, and carries out the asphalt performance test and detects.
Claims (2)
1. an asphalt film salt corrosion test is with the preparation facilities of sample, it is characterized in that, comprise baking oven (1) and at least one sample container (4), be equipped with in the described baking oven (1) by motor-driven turret (2), described each sample container (4) is positioned on the turret (2).
2. asphalt film salt corrosion test as claimed in claim 1 is characterized in that with the preparation facilities of sample, and described turret (2) is provided with at least one sample container putting hole (3).
