Abstract
The utility model relates to a special test mold for a segregation experiment of modified asphalt. The test mold comprises two wide plates with grooves, narrow plates, square plates with grooves, and a test mold support, wherein the test mold support comprises an upper separator plate and a lower bottom plate; the separator plate is provided with a plurality of constraint holes having the same size with the square plates; the bottom plate is provided with a plurality of grooves at corresponding positions; and the wide plates, the narrow plates and the square plates are inserted into rectangular groove containers through the grooves. The test mold solves the problem of waste of sample-containing bottles when the segregation experiment of the modified asphalt is finished, and provides a sample-accommodating device that can be used continuously.
Description
Technical field
The utility model relates to the special-purpose die trial of a kind of modified bitumen isolation test, is used for modified bitumen cementitious matter isolation test, belongs to the asphalt material testing equipment.
Background technology
Be widely used in polymer modified asphalt highway construction at home and abroad.But the density between polymkeric substance and pitch, viscosity, molecular weight, polarity and solubility parameter etc. differ greatly, and, from the thermodynamics analysis, are inconsistent between them.Polymkeric substance usually spontaneously condenses and emanates in matrix pitch.Therefore, the storage stability of polymer modified asphalt be in scientific research and actual production in the key issue that must solve.
At present isolation test is mainly adopted in the evaluation of modified bitumen storage stability.What China's " highway engineering pitch and Asphalt Mixture Experiment rules " (JTJ052-2000) and ASTM (ASTM D5976 and D5892) adopts is that modified bitumen is put into die trial, place a period of time under hot conditions after, (have be divided into upper, middle, and lower part) sampling respectively from die trial top and bottom, the difference of measuring its softening point is estimated the segregation degree of polymer modified asphalt.China's standard (JTJ036-98) regulation up and down softening point difference is specification product less than 2.5 ℃.The test procedure of regulation and stipulation is as follows:
(1) die trial can be selected aluminum pipe or glass tube, one section opening;
(2) weighing 50 gram pitch samples, the closing any opening end;
(3) die trial quiet 48 ± 1h of putting in 163 ± 5 ℃ of baking ovens;
(4) take out die trial from baking oven, put into the standing 4h of refrigerator of domestic refrigerator;
(5), if aluminum pipe is placed on aluminum pipe on solid flat board, be cut to three sections of decile once with the aluminum pipe that cutter will fill sample; , if glass tube, break glass into pieces gently with hand hammer, clean pitch sample is cut to three sections of decile.Beaker is put into respectively in top and bottom, will heat until sample can be fully mobile in standing 163 ± 5 ℃ of baking ovens of beaker;
(6) epimere and lower end sample are placed on same softening point tester and carry out simultaneously softening point measurement.No matter be that aluminum pipe or glass tube all cause serious waste, the die trial of using in each test all is in for waste and can not carries out the secondary utilization, does not meet the theory of present conservation-minded society.
The utility model content
The utility model provides a kind of modified bitumen isolation test special-purpose die trial for above-mentioned problems of the prior art, has solved after the modified bitumen isolation test finishes the problem of containing the waste of sample bottle, and the Sheng sample equipment of sustainable use is provided.
Realize the technical scheme that above purpose needs:
The special-purpose die trial of a kind of modified bitumen isolation test, comprise two wide plates with groove 1, narrow boards 2, be with reeded square plate 3 and die trial support 4, described die trial support 4 comprises that upper strata dividing plate 5 and lower floor's base plate 6 form, the constrained port identical with square plate 3 sizes arranged on dividing plate 5, on base plate 6, relevant position is fluted, wide plate 1 becomes cuboid container with narrow boards 2, square plate 3 by the groove interpolation, and the number of described constrained port and groove is a plurality of, can hold a plurality of cuboid container.
The preferred version of the special-purpose die trial of a kind of described modified bitumen isolation test, described die trial material used is metal material or the Inorganic Non-metallic Materials that do not react with pitch, described metal material is the common metal materials such as stainless steel, copper, iron, the material of described Inorganic Non-metallic Materials for not reacting with pitch, preferably glass.
Beneficial effect:
Can dismantle cleaning after the special-purpose die trial of modified bitumen isolation test described in the utility model is used, and can reuse, solve the present situation of the disposable utilization of the modified bitumen special-purpose die trial of segregation, the Sheng sample equipment of sustainable use is provided.
Description of drawings
Fig. 1 is the structural representation of the special-purpose die trial of modified bitumen isolation test described in the utility model.
Wherein: 1. wide plate 2. narrow boards 3. square plate 4. die trial support 5. dividing plate 6. base plates
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The assembling die trial, be placed in a square plate 3 in the groove on the base plate 6 of die trial support 4, and two wide plates 1 and two narrow boards 2 are assembled into rectangular parallelepiped, and the constrained port by die trial support 4 embeds in the groove of square-shaped metal plate 3.Described die trial is that stainless steel is made.
Pitch sample after heating is poured in die trial, pouring is to slightly exceeding die trial, at room temperature cooling 30min, to 60min, scrapes pitch unnecessary in die trial with scraper, presses another piece square plate 3 upper, and fixing whole die trial, then carry out follow-up test according to code requirement, when needs pitch is tested, only need the square plate at top 3 is opened, along groove, wide plate 1 and narrow boards 2 are removed, just can be taken out complete pitch sample.
It should be noted that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
