DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] See also Figure 1 , which shows a flow chart of an emulsified asphalt storage stability analysis method of the present application.

[0014] like Figure 1 As shown, the storage stability analysis method of emulsified asphalt specifically includes the following steps: Step S101, obtaining a first layer average particle diameter of a first layer of emulsified asphalt and a second layer average particle diameter of a second layer of emulsified asphalt in each storage tank, wherein the first layer of emulsified asphalt and the second layer of emulsified asphalt constitute all emulsified asphalt in the storage tank.

[0015] In this step, a laser particle size analyzer is used to obtain a first particle size distribution curve of the first layer of emulsified asphalt in a storage tank and a second particle size distribution curve of the second layer of emulsified asphalt; and the first layer average particle diameter of the first layer of emulsified asphalt in a storage tank and the second layer average particle diameter of the second layer of emulsified asphalt in a storage tank are determined according to the first particle size distribution curve and the second particle size distribution curve. In this way, the first layer average particle diameter of the first layer of emulsified asphalt and the second layer average particle diameter of the second layer of emulsified asphalt in each storage tank can be obtained.

[0016] Step S102, determining whether a first diameter difference between a first layer average particle diameter of a first layer of emulsified asphalt and a second layer average particle diameter of a second layer of emulsified asphalt is greater than a preset threshold, wherein the first layer of emulsified asphalt and the second layer of emulsified asphalt constitute all the emulsified asphalt in a storage tank.

[0017] As the storage time increases, emulsified asphalt with large particle size will settle and stratify. If the particle size of the emulsified asphalt in the storage tank is simply measured and the storage stability of the emulsified asphalt is directly determined based on the measurement results, it will be impossible to accurately determine the true stability of the emulsified asphalt due to the sedimentation and stratification. In particular, for a certain type of emulsified asphalt with a relatively long storage time, it is impossible to grasp its remaining storage time.

[0018] In this step, by judging whether the first diameter difference between a first layer average particle diameter of a first layer of emulsified asphalt and a second layer average particle diameter of a second layer of emulsified asphalt is greater than a preset threshold, the storage time of the emulsified asphalt can be grasped. For example, the sedimentation and stratification phenomenon of the emulsified asphalt with a longer storage time is more obvious, so the difference between the first layer average particle diameter and the second layer average particle diameter will be larger. Specifically, the first layer of emulsified asphalt is the upper layer of the storage tank, and the second layer of emulsified asphalt is the lower layer of the storage tank.

[0019] In a specific embodiment, after determining whether a first diameter difference between a first layer average particle diameter of a first layer of emulsified asphalt and a second layer average particle diameter of a second layer of emulsified asphalt is greater than a preset threshold, if it is not greater than the preset threshold, the second layer average particle diameter and the first layer average particle diameter are averaged to obtain a first target average particle diameter; the first target average particle diameter is input into the stability analysis model, and the stability analysis model outputs a stability result corresponding to the first target average particle diameter, i.e., the first target stability result of emulsified asphalt in a storage tank.

[0020] In this embodiment, if the difference between the average particle diameter of a first layer and the average particle diameter of a second layer is not greater than a preset threshold, it means that the emulsified asphalt in the storage tank may have just been stored or has been stored for a short time, and its sedimentation and stratification phenomenon is not obvious. Then, the average particle diameters of the two layers can be directly averaged, and the average value can be input into the preset stability analysis model to obtain the corresponding stability result, which can be directly used as the true stability result of the emulsified asphalt in the storage tank. The efficiency of the emulsified asphalt stability determination can be improved while ensuring the authenticity of the stability result as much as possible.

[0021] It should be noted that the stability analysis model can be obtained by inputting the control relationship between the average particle size and the storage stability into a neural network for training, or by fitting the average particle size and the storage stability to obtain a fitting curve equation.

[0022] For example, for the emulsified asphalt model GF AH-70, the fitting equation is Y=0.2476x 2 -0.3336, where x is the average particle size and Y is the storage stability. For another example, for the emulsified asphalt model TH AH-70, the fitting equation is Y=0.3025x 2 -0.4583. When the average particle sizes of GF AH-70 emulsified asphalt and TH AH-70 emulsified asphalt are less than 2.32 μm and 2.20 μm respectively, the emulsified asphalt meets the national standard for qualified products for 1 day storage stability.

[0023] Step S103, if the first diameter difference is greater than a preset threshold, a target first layer average particle diameter is selected from other first layer average particle diameters according to a preset selection strategy, wherein the other first layer average particle diameter is the first layer average particle diameter of the first layer of emulsified asphalt in other storage tanks.

[0024] In this step, other first-layer average particle diameters of the first layer of emulsified asphalt in other storage tanks within the same ambient temperature range are obtained; among the other first-layer average particle diameters, the first-layer average particle diameter with the largest difference from a certain first-layer average particle diameter is selected as the target first-layer average particle diameter.

[0025] In this embodiment, the larger the difference, the larger the interval between the storage time of the emulsified asphalt corresponding to the target first-layer average particle diameter and the storage time of the emulsified asphalt corresponding to the current first-layer average particle diameter. At this time, the emulsified asphalt corresponding to the target first-layer average particle diameter may be the most evenly mixed. Therefore, by obtaining the target first-layer average particle diameter with the largest difference from the current first-layer average particle diameter, the emulsified asphalt in the storage tank that has just been stored can be obtained in each storage tank as much as possible. In this way, on the premise of obtaining a relatively evenly mixed emulsified asphalt, the accuracy of the subsequent stability analysis of the emulsified asphalt in the current storage tank can be improved.

[0026] Because the increase in asphalt temperature reduces the viscosity of asphalt molecules, the emulsified asphalt with large particle size is easier to flow under the action of external force (for example, gravity), so the selected conditions need to be set within the same ambient temperature range.

[0027] Step S104, subtracting the target second layer average particle diameter corresponding to the target first layer average particle diameter from the second layer average particle diameter to obtain a second diameter difference, and determining whether the second diameter difference is greater than a preset threshold.

[0028] In a specific embodiment, after determining whether the second diameter difference is greater than a preset threshold, if the second diameter difference is not greater than the preset threshold, the second layer average particle diameter and the target second layer average particle diameter are averaged to obtain a second target average particle diameter; the second target average particle diameter is input into a stability analysis model, and the stability analysis model outputs a stability result corresponding to the second target average particle diameter, that is, the first target stability result of emulsified asphalt in a storage tank.

[0029] Step S105: If the second diameter difference is greater than a preset threshold, the second layer average particle diameter and the target second layer average particle diameter are respectively input into the stability analysis model, and the stability analysis model outputs a first stability result corresponding to the second layer average particle diameter and a second stability result corresponding to the target second layer average particle diameter.

[0030] Step S106, merging the first stability result and the second stability result according to a preset fusion strategy to obtain a target stability result of the emulsified asphalt in a storage tank.

[0031] In this step, the first diameter difference and the second diameter difference are added to obtain the target difference; weights are assigned to the first stability result and the second stability result according to a first ratio of the first diameter difference to the target difference and a second ratio of the second diameter difference to the target difference to obtain the target stability result of emulsified asphalt in a storage tank.

[0032] In summary, the method of the present application, by judging whether the first diameter difference between a first layer average particle diameter of a first layer of emulsified asphalt and a second layer average particle diameter of a second layer of emulsified asphalt is greater than a preset threshold, can obtain the emulsified asphalt in the storage tank that has just been stored in each storage tank as much as possible, so as to facilitate the subsequent stability analysis of the emulsified asphalt in a storage tank, and assign weights to the first stability result and the second stability result according to a first ratio of the first diameter difference to the target difference and a second ratio of the second diameter difference to the target difference, so as to correct the first stability result, thereby improving the authenticity of the stability measurement of the emulsified asphalt in a storage tank as much as possible.
