Abstract
Description
Technical Field
[0001] This invention belongs to the field of road engineering material testing technology, specifically relating to a multi-dimensional testing and prediction method for the bonding performance of waterproof adhesive layer materials. Background Technology
[0002] In asphalt pavement structures, the waterproof bonding layer is a crucial component connecting the upper and lower structural layers, and its bonding performance directly affects the overall load-bearing capacity, waterproofing effect, and service life of the pavement. If the bonding strength of the waterproof bonding layer material is insufficient, it can easily lead to pavement layer delamination, water seepage, potholes, and other defects, which not only increase maintenance costs but also reduce road safety.
[0003] Currently, existing testing methods for asphalt pavement tack coat materials primarily focus on the physical properties of the materials themselves, such as penetration and ductility. These tests often employ single environments (e.g., ambient temperature and pressure) and fail to consider the combined effects of multiple factors on the actual pavement, such as temperature cycling, UV aging, and rain erosion. The lack of multi-environment simulation testing for interlayer bonding performance results in inaccurate representation of the material's actual performance and lacks simulation testing of the actual bonding effect after construction. Furthermore, some bond strength testing methods are complex to operate, and the results deviate from actual engineering scenarios, making it difficult to accurately guide construction quality control. In addition, existing methods lack direct data support for controlling the dosage of commonly used tack coat materials such as sprayed emulsified asphalt, easily leading to material waste or substandard construction quality. Existing methods for testing the waterproofing performance of waterproof tack coat materials are limited. Conventional immersion tests (e.g., 24-hour soaking) can only qualitatively observe peeling and cannot quantify the waterproofing level. Artificial seepage tests after on-site core drilling are greatly affected by subjective factors. The current waterproofing adhesive materials cannot be quickly tested for waterproofing performance, and their quality varies greatly. Premature failure of the waterproofing adhesive layer leads to early defects such as interlayer slippage and pitting. Therefore, there is an urgent need for a multi-dimensional testing method that can simulate actual construction effects, is easy to operate, and provides accurate testing to fill the gaps in existing technologies.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

S4. Place the rutted slab specimen processed in step S3 into a simulation system of the target environment for curing; the target environment is the environment of the target application site of the waterproof adhesive layer material to be tested. S5. After curing, the rutted slab specimens are subjected to adhesion performance tests. The adhesion test results are calculated, and the arithmetic mean is taken after removing outliers as the adhesion test result. The adhesion test results are used to determine the suitability of the waterproof adhesive layer material to be tested in the target environment.
[0006] In one embodiment of the present invention, the simulation system of the target environment includes a temperature control module, a light control module and a dynamic water pressure control module, which are used to be turned on independently or in combination to adapt to the simulation requirements of different target environments. The curing of the rutted slab specimens includes environmental simulation curing using at least one of a temperature control module, a light control module, and a dynamic water pressure control module.
[0007] In one embodiment of the present invention, the temperature control module has a temperature control range of -30℃ to 80℃; the illumination control module uses a UVB-313 lamp tube, and the irradiance range of the UVB-313 lamp tube is 0.55 to 0.70 W / m². 2 @310nm, adjustable according to the UV intensity of the target environment.
[0008] In one embodiment of the present invention, the dynamic water pressure control module is intermittently activated, and the spray pressure range of the dynamic water pressure control module is 0.1 to 0.3 MPa. The percentage of the total activation time of the dynamic water pressure control module to the duration of the health maintenance cycle is P, where P is the annual precipitation probability of the target environment. The total spray volume of the dynamic water pressure control module is (the annual average precipitation of the target environment / 365) × the duration of the health maintenance cycle.
[0009] In one embodiment of the present invention, the preparation of the rutting plate specimen includes the preparation of an asphalt mixture rutting plate or a cement concrete rutting plate.
[0010] In one embodiment of the present invention, the asphalt mixture used in the asphalt mixture rutting slab is any one of AC-10, AC-13, and AC20.
[0011] In one embodiment of the present invention, the preparation of asphalt mixture rutting slabs includes: Precast asphalt mixture rutting slabs were prepared using the same asphalt mixture used in the pre-designed construction project.

[0014] Secondly, this invention provides a method for predicting the bonding performance of waterproof adhesive layer materials. Based on data obtained from the aforementioned multi-dimensional testing method, a prediction model for the bonding performance of waterproof adhesive layer materials is established. The prediction model is as follows: Y = aX1 + bX2 - cX3 - d; Wherein, Y is the predicted adhesion strength; X1 is the asphalt percentage content in the waterproof adhesive layer material; X2 is the annual average temperature of the target environment; X3 is the annual average precipitation rate of the target environment; a, b, and c are data obtained by the multidimensional testing method according to any one of claims 1-9, calculated by multiple linear regression analysis, where the value of a ranges from 0.010 to 0.020, the value of b ranges from 0.035 to 0.050, the value of c ranges from 0.005 to 0.007; and the value of d ranges from 0.15 to 0.35, where d is the comprehensive correction coefficient for ultraviolet radiation intensity and asphalt modification type.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

[0016] 2. The test conditions in this invention can be customized according to the climate and hydrological data of the specific project location, so that the test results can be directly used for the selection and quality control of waterproof adhesive layer materials, realizing the leap from "laboratory indicators" to "engineering applicability".
[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description
[0018] Figure 1 This is a flowchart illustrating a multi-dimensional testing method for the bonding performance of a waterproof adhesive layer material provided in an embodiment of the present invention. Detailed Implementation
[0019] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following describes in detail, with reference to the accompanying drawings and specific embodiments, a multi-dimensional testing method and prediction method for the bonding performance of a waterproof adhesive layer material proposed according to the present invention.
[0020] The foregoing and other technical contents, features, and effects of the present invention will be clearly presented in the following detailed description of specific embodiments in conjunction with the accompanying drawings. Through the description of the specific embodiments, a more in-depth and concrete understanding can be gained of the technical means and effects adopted by the present invention to achieve its intended purpose. However, the accompanying drawings are for reference and illustration only and are not intended to limit the technical solutions of the present invention.
[0021] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations are intended to cover non-exclusive inclusion, such that an article or device that comprises a list of elements includes not only those elements but also other elements not expressly listed.
[0022] This invention provides a multi-dimensional testing method for the bonding performance of waterproof adhesive layer materials, see [link to relevant documentation]. Figure 1 The testing method includes the following steps.
[0023] S1. Prepare rut plate specimens.
[0024] In some examples, the preparation of rutting slab specimens includes the preparation of asphalt mixture rutting slabs or cement concrete rutting slabs.
[0025] In some examples, the asphalt mixture used in the asphalt mixture rutting slabs is any one of AC-10, AC-13, or AC-20 gradation.
[0026] For example, the preparation of asphalt mixture rutting slabs includes: preparing precast asphalt mixture rutting slabs according to the relevant standards in the "Test Procedures for Asphalt and Asphalt Mixtures in Highway Engineering" (JTG E20). Specifically, the dimensions, compaction degree, and mixture gradation of the precast asphalt mixture rutting slabs must be consistent with or close to the asphalt mixture used in the pre-construction project to ensure the consistency and representativeness of the test benchmark.
[0027] Precast asphalt mixture rutting slabs were cured in an environment with a temperature of 25±2℃ and a humidity of 50±5% for 24 hours to eliminate internal stress in the specimens and obtain asphalt mixture rutting slabs.
[0028] For example, the preparation of cement concrete rutting slabs includes: customizing wooden molds according to the dimensions of the cement concrete rutting slabs in advance, and preparing precast cement concrete rutting slabs according to the molding method of cement concrete rutting slabs. The various indicators of the precast cement concrete rutting slabs are consistent with or close to the indicators of the cement concrete used in the pre-construction project, ensuring the consistency and representativeness of the testing benchmarks.
[0029] Precast cement concrete rutting slabs are cured for 7 days at a temperature of 25±2℃ and a humidity of 50±5% to ensure strength formation. They are then mechanically roughened (e.g., with a steel brush), cleaned, and dried to obtain the cement concrete rutting slabs. For example, the roughening depth is 0.5–1 mm, the surface roughness Ra of the cement concrete rutting slabs is ≥0.8 μm, and the surface moisture content is ≤2%.
[0030] S2. Apply the waterproof adhesive layer material to be tested to the pre-designed bonding surface of the rutted slab specimen and allow it to initially cure for 20–22 hours; the coating thickness should be 0.3 mm–0.8 mm. Specifically, use a brush to evenly apply the waterproof adhesive layer material to the pre-designed bonding surface, ensuring no missed areas or accumulation. After application, place the specimen in a standard environment to allow the waterproof adhesive layer material to initially cure.
[0031] For example, the waterproof bonding layer material is an asphalt-based waterproof bonding material, and the material meets the material requirements of relevant construction technical specifications. Further, the asphalt-based waterproof bonding material can be any one of sprayable emulsified asphalt, polymer-modified emulsified asphalt, and water-based epoxy-modified emulsified asphalt.
[0032] S3. Using epoxy adhesive, uniformly fix multiple spindles onto the surface of the pre-cured waterproof adhesive layer material to be tested. The distance between any two adjacent spindles should not be less than 40mm to avoid mutual interference during pull-out testing. Simultaneously, the uniform distribution of multiple spindles can cover the entire bonding surface of the specimen, reducing the impact of local non-uniformity on the test results. Allow to stand for at least 4 hours to allow the waterproof adhesive layer material to be tested to fully cure and for the spindles to form a stable bonding interface with the waterproof adhesive layer material.
[0033] For example, a standard ingot with a diameter of 20mm and made of high-strength alloy steel can be used.
[0034] For example, the standard spindles are evenly arranged so that the test data can cover all positions of the rut plate specimen, improving the accuracy of the test results and effectively reducing the influence of random errors in the test and local non-uniformity of the specimen.
[0035] S4. Place the rutted plate specimen processed in step S3 into a simulation system of the target environment for curing. The target environment is the environment of the target application site of the waterproof adhesive layer material to be tested. Simulate the multi-factor coupling effect of the target environment to make the aging state of the specimen consistent with the actual engineering scenario.
[0036] In one example, the simulation system for the target environment includes a temperature control module, a lighting control module, and a dynamic water pressure control module, which can be activated independently or in combination to adapt to the simulation requirements of different target environments. Specifically, the temperature control module simulates road surface temperatures ranging from extremely cold to extremely hot weather; the lighting control module uses ultraviolet lamps to simulate the aging effects of outdoor sunlight on road surface materials; and the dynamic water pressure control module simulates the impact of water pressure from rainfall and other external forces on the performance of the waterproof adhesive layer.
[0037] Curing rutted slab specimens involves using at least one of three modules: temperature control, illumination control, and dynamic water pressure control, to simulate environmental curing. In other words, during rutted slab specimen curing, one of these modules can be activated, for example, the temperature control module can be activated to maintain the simulated environmental temperature; alternatively, two or three modules can be activated, and the simulation program can be set according to the actual conditions of the target environment. This provides great testing flexibility, allowing for studies of single-factor effects as well as complex environmental simulations of the coupled effects of multiple factors such as temperature, ultraviolet radiation, and dynamic water pressure, more closely reflecting the comprehensive environmental stresses actually experienced by pavement materials.
[0038] For example, the temperature control module has a temperature control range of -30℃ to 80℃, which is a wide temperature adjustment range and can simulate the road surface temperature in most regions.
[0039] For example, the lighting control module uses a UVB-313 lamp, the irradiance of which ranges from 0.55 to 0.70 W / m². 2 @ 310nm, adjustable according to the UV intensity of the target environment. In other words, this example simulates material aging under different altitude conditions and service life through UV lamp irradiation. In practical applications, the "spectral matching principle" is followed. When simulating natural outdoor aging, UVB-313 lamps that match the solar UV spectrum are preferred to accelerate the simulation of aging under strong UV environment.
[0040] For example, the dynamic water pressure control module is intermittently activated, and the spray pressure range of the dynamic water pressure control module is 0.1 to 0.3 MPa; the percentage of the total activation time of the dynamic water pressure control module to the duration of the maintenance cycle is P, where P is the annual precipitation probability of the target environment; the total spray volume of the dynamic water pressure control module is (annual average precipitation of the target environment / 365) × duration of the maintenance cycle.
[0041] S5. After curing, conduct adhesion performance tests on the rutted slab specimens and calculate the adhesion test results. The adhesion test results are used to determine the suitability of the waterproof adhesive layer material to be tested in the target environment. In terms of data processing of the test results, statistical analysis is performed on the effective test values of each spindle on the same rutted slab specimen, outliers are removed, and the arithmetic mean of the remaining test values is calculated; and based on the test results, it is judged whether the waterproof adhesive layer material meets the construction requirements.
[0042] This invention employs a composite environmental simulation system that integrates key environmental factors such as temperature cycling, ultraviolet aging, and dynamic water erosion. It can simulate various target environments, from simple to complex, ensuring that the curing conditions of the specimens closely approximate the target environment of actual applications. Therefore, the test results obtained by the testing method provided by this invention are more practical and convincing. These results can be directly used for the comparison and quality control of waterproof adhesive layer materials, achieving a leap from "laboratory indicators" to "engineering applicability." It is suitable for performance evaluation and quality control of waterproof adhesive layer materials in asphalt pavement construction for highways, municipal roads, and other similar applications.
[0043] The present invention also provides a method for predicting the bonding performance of waterproof adhesive layer materials. The prediction method is based on the data obtained by the above-mentioned multi-dimensional test method, and establishes a prediction model for the bonding performance of waterproof adhesive layer materials. The prediction model is expressed as: Y = aX1+bX2﹣cX3﹣d; Where Y represents the predicted adhesion strength (MPa); X1 represents the asphalt percentage content (%) in the waterproof adhesive layer material; X2 represents the annual average temperature of the target environment (°C); X3 represents the annual average precipitation rate of the target environment (%); a, b, and c are data obtained using the above multi-dimensional testing methods, calculated through multiple linear regression analysis, with a ranging from 0.010 to 0.020, b ranging from 0.035 to 0.050, and c ranging from 0.005 to 0.007; d ranges from 0.15 to 0.35, and d is a comprehensive correction coefficient for ultraviolet radiation intensity and asphalt modification type. d can be determined based on the ultraviolet irradiance of the target environment (W / m²). 2 The values (@310nm) and the asphalt modification type are determined, and the specific values are calibrated through experiments.
[0044] In one example, the prediction model is Y = 0.015X1+0.042X2-0.006X3-0.247.
[0045] The following specific embodiments further illustrate the multi-dimensional testing method for the bonding performance of the waterproof adhesive layer material provided by the present invention.
[0046] Example 1 Asphalt mixture rutting slabs measuring 30cm × 30cm × 5cm were prepared using AC-10 graded asphalt mixture. High viscoelastic modified emulsified asphalt with an asphalt content of 65% was prepared. 90g of the high viscoelastic modified emulsified asphalt was evenly applied to the asphalt mixture rutting slabs and allowed to stand for 24 hours. Then, 25 20mm spindles were bonded to the surface of the applied adhesive material using epoxy adhesive. The pre-set construction location was Xi'an, with an average annual temperature of approximately 13℃, moderate ultraviolet radiation, and an annual precipitation rate of 50%. Based on these target environmental conditions, the temperature control module was set to -10~60℃, with cyclical temperature changes. UVB-313 lamps were used for ultraviolet irradiation at an intensity of 0.55 - 0.60 W / m² @ 310nm, set to a medium level. Simultaneously, a dynamic water pressure control module was intermittently used for spraying the specimen surface for 50% of the curing period. The entire curing period for the specimens was 10 days. After setting the relevant parameters of the instrument, an adhesion test was conducted using the testing instrument with a range of 0.7~20MPa. The test values were read, and the asphalt adhesion fracture interface was observed. According to the test results, in this embodiment, the high viscoelastic modified emulsified asphalt with an asphalt content of 65% was used as a waterproof bonding layer material in Xi'an, with an average adhesion strength of 0.97MPa. The test results are shown in Table 1.
[0047] Table 1. Adhesion Test Results
[0048] Example 2 Asphalt mixture rutting slabs measuring 30cm × 30cm × 5cm were prepared using AC-20 graded asphalt mixture. Emulsified asphalt (50% asphalt content), SBR (styrene-butadiene rubber) modified emulsified asphalt, and water-based epoxy modified emulsified asphalt were prepared. 72g of each of these three materials was evenly applied to the asphalt mixture rutting slabs and allowed to stand for 24 hours. Three sets, totaling 18 20mm spindles, were then bonded to the surface of the prepared adhesive layer using an epoxy adhesive. The intended construction site was Yulin, with an average annual temperature of approximately 8.3–10.7℃, moderate to strong ultraviolet radiation, and an annual precipitation rate of 10%. Based on the above target environmental conditions, the temperature control module was set to -10~30℃, with cyclical temperature changes. UVB-313 lamps were used for ultraviolet irradiation at an intensity of 0.60-0.70 W / m² @ 310nm, set to a high level. Simultaneously, a dynamic water pressure system was intermittently used for spraying the specimen surface, accounting for 10% of the curing cycle. The entire curing cycle for the specimens was 10 days. After setting the relevant instrument parameters, an adhesion test was conducted using a testing instrument with a range of 0.7~20MPa. Test values were read, and the asphalt adhesion fracture interface was observed. According to the test results, the three waterproof adhesive layer materials in Example 2—50% asphalt emulsified asphalt, SBR modified emulsified asphalt, and water-based epoxy modified emulsified asphalt—showed average adhesion strengths of 0.86MPa, 1.44MPa, and 1.16MPa, respectively, when used as waterproof adhesive layer materials in the Yulin area. The specific test results for 18 spindles are shown in Table 2.
[0049] Table 2. Results of comparative experiments
[0050] Based on the above test results, it can be concluded that among the three materials, SBR emulsified asphalt has the highest bonding strength. In the Yulin area, SBR modified emulsified asphalt is recommended as the interlayer bonding material for road surfaces.
