Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The invention designs a quantification method for testing the segregation degree of asphalt mixture by utilizing the adhesiveness of asphalt cement at high temperature (130-170 ℃), the thickness of oil film coated on the surfaces of crushed stone and filler in the mixture, and the like.
As shown in fig. 1, the method for detecting the segregation degree of the asphalt mixture comprises the following steps:
sampling the asphalt mixture according to a quartering method to obtain a sample; wherein the mass of the sample is in the range of 1000-1500 g.
The asphalt mixture can be a fine-grain type, medium-grain type or coarse-grain type mixture, and the fine-grain type mixture can be AC-10 or AC-13 asphalt mixture; the medium particle type mixture can be, for example, an AC-16 and AC-20 asphalt mixture; the coarse-grained mixture may be, for example, an AC-25, AC-30 asphalt mixture. When a fine-grained mix is used, the mass of the sample may be 1000g; when a medium particle type mixture is used, the mass of the sample may be 1200g; when a coarse-grain mix is used, the mass of the sample may be 1500g.
In the embodiment of the invention, the AC-13 fine-grain mixture is adopted, and specifically, coarse aggregate, fine aggregate, mineral powder filler and asphalt are mixed at 130-170 ℃ and cooled to room temperature to prepare the asphalt.
Wherein the coarse aggregate is formed by combining a first-grain-size coarse aggregate, a second-grain-size coarse aggregate and a third-grain-size coarse aggregate.
The grain sizes of the first grain size coarse aggregate, the second grain size coarse aggregate and the third grain size coarse aggregate are 10-15 mm, 6-10 mm and 3-6 mm in sequence.
The mass percentage of the first grain size coarse aggregate, the second grain size coarse aggregate and the third grain size coarse aggregate is 15-25%, 17-30% and 13-25% in sequence.
The grain diameter of the fine aggregate is below 2.36mm, and the mass percentage of the fine aggregate is 26-36%.
The mass percentage of the mineral powder filler is 2-6%.
The mass percentage of the asphalt is 3.84-5.66%.
Sorting aggregate particles with the particle size of more than or equal to 4.75mm from the sample; note that during sorting, the action is gentle, avoiding the falling off of fine aggregates adhering to the aggregate particles.
Soaking coarse aggregate particles in trichloroethylene solution or kerosene for more than or equal to 30min, and properly stirring with a glass rod until asphalt is completely dissolved, wherein no asphalt is on the surface of the aggregate.
The aggregate is extracted and dried for 3 to 5 hours at the temperature of 105+/-5 ℃ and weighed and recorded as the mass m1.
And screening, drying and weighing the aggregate particles to obtain aggregate particles with the particle size of more than 2.36mm, and weighing the aggregate particles and marking the aggregate particles as mass m2.
The resolution L, l= ((m 1-m 2)/m 1) 100 is calculated.
Generally, the larger the segregation L value, the better the segregation resistance of the asphalt mixture.
However, the segregation degree L has an upper limit value, the maximum asphalt dosage of the mixture is measured according to the maximum asphalt dosage test method of the asphalt mixture, then the asphalt mixture is obtained by stirring the maximum asphalt dosage, and finally the segregation degree L obtained by the measurement method is the upper limit value.
The optimal oil-stone ratio of the asphalt mixture corresponds to the optimal segregation degree, and whether the oil-stone ratio of the asphalt mixture is within the optimal range value can be indirectly judged by detecting the segregation degree of the asphalt mixture. And for a certain asphalt mixture, the optimal oil-stone ratio of the asphalt mixture needs to be determined according to a mix proportion design method, and the corresponding segregation degree L is the optimal range value of the asphalt mixture within the fluctuation range (plus or minus 0.3%) of the optimal oil-stone ratio.
Hereinafter, a method for detecting the segregation degree of asphalt mixture according to the present invention will be described in detail by way of specific examples.
Example 1:
1. taking a stirred fine-grained asphalt mixture meeting the requirement of mixing temperature (130-170 ℃), dividing samples by a quarter method, diagonally taking two samples, and sampling 1000g of mass.
2. Placing the sample into a clean stainless steel square plate, spreading the mixture by a shovel to form a thin layer with separated aggregate and no overlapping, and cooling to room temperature.
3. Aggregate particles having a particle size above 4.75mm were sorted from the cooled samples.
4. Placing the sorted aggregate particles into a glass beaker, soaking for 30min with trichloroethylene, stirring with a glass rod to dissolve asphalt, and separating fine aggregate from the surface of the aggregate; then extracting, drying at 105 ℃ for 3 hours, weighing and marking the mass as m1.
5. The dried and weighed mixture is sieved by a square sieve with 2.36mm, and the broken stone remained on the sieve is weighed, and the mass is recorded as m2.
6. To ensure accuracy, the above test was performed in parallel twice, the degree of resolution was calculated, the degree of resolution was noted as L, the calculation formula l= ((m 1-m 2)/m 1) 100, and the result of the two calculations could not exceed 3% of the average.
In the invention, the segregation degree L represents asphalt adhered to coarse aggregates, fine aggregates below 2.36mm and mineral powder filler, and the segregation degree L accounts for the mass proportion of the total asphalt mixture.
Examples 2 to 3 used the same test method as example 1, except that the mass percentages of coarse aggregate, fine aggregate, mineral powder filler and asphalt in the asphalt mixture, the oil-stone ratio and the process parameters in each step were different. The parameters of each step in the detection methods of examples 1 to 3 are summarized in tables 1 to 2.
Table 1 summary of the respective constituent materials of the asphalt mixtures in examples 1 to 3
Table 2 summary of process parameters in the detection methods of examples 1 to 3
Meanwhile, the segregation degree L is calculated according to the detection method in the embodiments 1-3, the oilstone ratio in the embodiments 1-3 is calculated by adopting the conventional calculation method in industry, and the result is shown in Table 3 in detail.
TABLE 3 summary of results for the oil-to-stone ratios and segregation degree in examples 1 to 3
| Group of | Wheal ratio (%) | Degree of segregation L |
| Example 1 | 4.0 | 15.8 |
| Example 2 | 5.3 | 32.3 |
| Example 3 | 5.6 | 34 |
As can be seen from table 3, the segregation degree L is obtained by the detection method in the present invention, and whether the asphalt mixture has an oil-stone ratio within the optimum value range is indirectly judged by the segregation degree L. If the whetstone ratio of 5.3% in example 2 was found to be the optimum value, the corresponding degree of segregation L32.3 was the optimum degree of segregation, and the range value (27-34) of the corresponding degree of segregation L in the range of 5.0-5.6% of whetstone ratio was further obtained as the preferred degree of segregation (the preferred range value of 32.4, corresponding to the whetstone ratio of 5.0-5.6%).
It is also apparent from the combination of example 1 and example 3 that the whetstone ratio in example 1 is 4.0%, and the segregation degree L15.2 is detected to be lower than the value of the preferable segregation degree range, which means that the segregation degree L is lower and the asphalt content is lower; the oil-stone ratio in example 3 was 5.6%, and the segregation degree L34, which is the upper limit value of the segregation degree range value and above which the asphalt content in the mixture was higher, was detected.
The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
