Description

Technical Field

[0001] This invention relates to the field of road construction and maintenance materials technology, specifically to a method for determining the effective construction time of mixed water-based epoxy emulsified asphalt. Background Technology

[0002] In recent years, energy consumption and environmental pollution during road construction and maintenance have received increasing attention from researchers. Emulsified asphalt, due to its ability to be sprayed and mixed at ambient temperatures, offers advantages such as environmental friendliness, energy saving, ease of construction, and safety. Currently, it is widely studied and applied in fog seals, micro-surfacing, tack coats, bridge deck waterproofing layers, and cold patching materials. To meet the increasing demands for road construction and maintenance quality from growing traffic volumes and heavy vehicles, and to further improve the mechanical strength, high and low temperature performance, and durability of emulsified asphalt, high-performance polymer emulsified asphalts such as mixed-type waterborne epoxy emulsified asphalt are attracting increasing attention from researchers. However, currently, as a road bonding material, its curing performance is mostly evaluated using the final complete curing time, lacking specific stage indicators for different usage environments, construction procedures, and functional positioning. A complete evaluation system for the full-process curing performance of waterborne epoxy emulsified asphalt materials has not yet been established. The lack of high-precision testing methods and vague technical indicator requirements are all detrimental to the further promotion and development of waterborne epoxy emulsified asphalt materials in the road materials field.

[0003] In practical engineering applications, the physical form of mixed waterborne epoxy emulsified asphalt changes continuously with different degrees of curing, successively exhibiting an evolution process from liquid to gel to solid. The material itself exhibits problems such as large viscosity changes, rapid viscosity increase, and difficulty in monitoring the degree of curing. There is a lack of clear stage division indicators for the material morphology changes of mixed waterborne epoxy emulsified asphalt materials during construction and curing processes, which is not conducive to controlling the successive time of paving construction and determining the time nodes for mixing, paving, and compaction of mixed waterborne epoxy emulsified asphalt materials, thus affecting the improvement of construction efficiency and construction quality.

[0004] Therefore, in the actual engineering application of mixed waterborne epoxy emulsified asphalt, the curing performance of mixed waterborne epoxy emulsified asphalt materials is evaluated by using a single curing time, making it difficult to monitor the degree of curing and failing to meet the needs of efficient construction organization. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a method for determining the effective construction time of mixed waterborne epoxy emulsified asphalt. This method is based on the principle that the viscosity index of a binder will undergo a sudden change when it undergoes a morphological transformation between different physical forms. By setting technical indicators for the construction working time and gel time of mixed waterborne epoxy emulsified asphalt, the curing process of the mixed waterborne epoxy emulsified asphalt material is sequentially staged. This effectively avoids the shortcomings of existing methods that use a single curing time to evaluate the curing performance of mixed waterborne epoxy emulsified asphalt materials. It can effectively monitor the degree of curing of mixed waterborne epoxy emulsified asphalt materials, thereby meeting the needs of efficient construction organization in practice.

[0059] Example

[0060] The preferred embodiments of the present invention are as follows:

[0061] As described in the background section, existing technologies suffer from significant operational randomness, highly dispersed results, and an inability to effectively match actual construction procedures. To address these technical issues, this application proposes a method for determining the effective construction time of mixed waterborne epoxy emulsified asphalt.

Based on the principle that viscosity indicators undergo numerical abrupt changes when the binder material undergoes morphological transformation between different physical forms, this method effectively eliminates interference from environmental and human factors on the test results, meets the requirements of quantitative testing, improves the accuracy of sampling tests, and stages the curing process of mixed waterborne epoxy emulsified asphalt. This allows for close integration with actual engineering construction procedures such as mixing, paving, and compaction. While meeting the needs of efficient on-site construction organization, this method also provides a reference for the initial research, comparison, and combination design of mixed waterborne epoxy emulsified asphalt materials.

[0062] This embodiment provides a method for determining the effective construction time of mixed water-based epoxy emulsified asphalt, specifically including:

[0067] (5) Install the selected rotor and sample tube onto the viscometer in sequence, lower the height of the viscometer so that the rotor is inserted into the water-based epoxy emulsified asphalt liquid surface of the sample tube to the specified test height.

[0068] (6) Keep the asphalt sample in a constant temperature container until it reaches the equilibrium temperature required for the test. Observe the change in viscosity value. When the reading after the decimal point is stable, read the value and record it. Read the value once every 20 seconds, and read it three times in a row. Take the average value of the three readings as the single measurement value.

[0069] (7) Set the automatic detection cycle and automatic detection interval to obtain multiple sets of viscosity data. The specific selection of the automatic detection cycle and detection interval should take into account the actual temperature and humidity environment of the material in the field.

[0075]

[0076] In the above method, it is preferred that in step (1), the sample container is a glass cup, preferably a 100ml flat-bottomed glass beaker.

[0077] Furthermore, in step (1), the viscometer is a Blockfield viscometer with a maximum range of 300 Mcp.

[0078] Furthermore, in step (1), the volume of the mixed waterborne epoxy emulsified asphalt is 35 ml.

[0079] Furthermore, in step (2), the sample tube is placed in a constant temperature and humidity cylinder with temperatures of 40°C and 60°C, relative humidity of 60%RH, and waterborne epoxy content of 15% and 20%.

[0080] Furthermore, in step (2), the viscometer used has the function of automatically detecting and storing data, with a maximum range of 300 MPa.

[0081] Further, in step (3), rotor No. 27 is selected with a rotational speed of 20 r / min.

[0082] Further, in step (7), refer to Table 2 for a summary of the test sample composition codes; set the automatic detection cycle of sample E-Ⅰ to 2h and the automatic detection interval to 3min; set the automatic detection cycle of sample E-Ⅲ to 1h and the automatic detection interval to 3min; set the automatic detection cycle of sample C-Ⅰ to 6h and the automatic detection interval to 9min; set the automatic detection cycle of sample C-Ⅲ to 5h and the automatic detection interval to 6min.

[0083] Furthermore, in step (8), the shape of the obtained curve tends to be a nonlinear regression curve.

[0084] The data used is in, The initial viscosity of the mixed waterborne epoxy emulsified asphalt sample at the test temperature. Viscosity data collected at each detection interval; such as Figure 1 , Figure 2 and Figure 3 As shown, the time-viscosity curves for sample E-Ⅰ, sample C-Ⅲ, and sample C-Ⅰ were obtained respectively.

[0085] Furthermore, in step (9), such as Figure 4 He Ru Figure 5 As shown, viscosity data were obtained at each measurement point in sequence. Analysis revealed that the minimum viscosity of this mixed waterborne epoxy emulsified asphalt was 220 mPa·s, and the maximum viscosity was 10200 mPa·s. Therefore, the corresponding construction time node T1 for this sample under these conditions was 9 min, and the gelation end time node T3 was 42 min. Slope analysis of the fitted curve showed that the slope of the curve was close to 1 at 27 min. Therefore, the gelation start time node T2 was 27 min.

[0086] Furthermore, based on the construction working time T1, gel start time T2, and gel end / solid start time T3 of the mixed waterborne epoxy emulsified asphalt sample obtained by the above method, the entire curing process of the mixed waterborne epoxy emulsified asphalt sample was successfully and accurately divided into liquid, gel, and solid states. This effectively fills the current gap in the detection of the curing degree of mixed waterborne epoxy emulsified asphalt. According to the viscosity requirements of the construction materials during actual construction processes such as mixing, paving, and compaction (initial compaction, intermediate compaction, and final compaction), the construction working time nodes T1 and T3 are gradually integrated. The timing of the road material mixing and paving construction processes is aligned with the time nodes. The start time node T2 of the gel state corresponds to the end time node of the initial and secondary compaction construction processes of the road material. The end time node T3 of the gel state / start time node of the solid state corresponds to the end time node of the final compaction construction process of the road material. This achieves a one-to-one correspondence between the entire curing process of the mixed waterborne epoxy emulsified asphalt sample and the actual construction process, effectively meeting the needs of efficient construction organization in actual engineering projects. It also provides a reference for the initial research, comparison, and combination design of mixed waterborne epoxy emulsified asphalt materials in road engineering.

[0087] This embodiment provides a method for determining the effective construction time of mixed waterborne epoxy emulsified asphalt. Compared with traditional methods such as cotton blowing and finger touch, it can effectively eliminate the interference of environmental factors and human factors on the curing test results, meet the requirements of quantitative testing, and improve the accuracy of sampling tests. It proposes working time and gel time indicators for mixed waterborne epoxy emulsified asphalt, and sequentially stages the actual curing process of mixed waterborne epoxy emulsified asphalt, gradually distinguishing it into liquid, gel, and solid states. This method effectively avoids the shortcomings of existing methods that use a single curing time to evaluate the curing performance of mixed waterborne epoxy emulsified asphalt materials. It adopts a more rigorous and scientific testing method and technical indicators, minimizing the error caused by environmental factors and human operation. It proposes working time and gel time test indicators for mixed waterborne epoxy emulsified asphalt, and closely correlates them with the mixing, paving, and compaction processes in the actual construction of mixed waterborne epoxy emulsified asphalt, to meet the needs of efficient construction organization and provide a reference for the further promotion and application of mixed waterborne epoxy emulsified asphalt materials in the road sector.
