Description

Technical Field

[0001] The invention relates to the technical field of asphalt pavement construction, and in particular to an intelligent compaction method for an asphalt pavement. Background Art

[0002] The degree of compaction seriously affects the performance and service life of asphalt pavement. Insufficient compaction can easily cause rutting, water damage and other diseases; on the contrary, excessive compaction can easily cause aggregate crushing, oiling of the road surface and other phenomena. Therefore, during its construction, it is necessary to ensure that the asphalt pavement has a reasonable degree of compaction to ensure that it has good service performance during the operation stage. In engineering practice, the number of rolling passes and other processes are determined by test roads and combined with engineering experience. The number of rolling passes determined by the test road is used for control, and a very small amount of coring tests are used as verification. However, as a temperature-sensitive viscoelastic material, the compaction characteristics of asphalt mixture are closely related to its rolling temperature and rate. When the temperature is high, it is easy to compact, and when the temperature is low, compaction is extremely difficult; on the other hand, from the perspective of energy conservation, when other conditions are constant, the work output by the roller per unit time is constant. Therefore, when the travel speed of the roller changes, the compaction work obtained by the mixture per unit area will inevitably change. In the actual construction process, the temperature of the mixture is affected by the production, transportation, paving and construction climate of the mixing station, and it is difficult to ensure stability, and the speed of the roller is also difficult to maintain constant. Therefore, it is difficult to ensure that the compaction degree meets the relevant requirements by simply controlling the number of passes. A very small amount of coring test only represents the results of the "point" and cannot reflect the compaction degree of the "surface". In addition, the coring test is a post-verification. Once the compaction degree is insufficient, it can only be reworked, resulting in great waste. Summary of the invention

[0058] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0059] Please refer to Figure 1 This embodiment provides an asphalt pavement intelligent compaction method, comprising the following steps:

[0063] S4. Obtain the standard rolling rate and actual rolling rate of the compaction machinery at the construction site;

[0064] S5. According to the functional equivalence principle, the actual number of rotary compactions is obtained by using the standard rolling rate, the actual rolling rate and the standard number of rotary compactions;

[0065] S6, substituting the actual number of rotary compaction times and the actual internal temperature of the asphalt mixture at the construction site into the first function to obtain an actual degree of compaction;

[0066] When the actual compaction degree is greater than or equal to the standard compaction degree, the actual rolling rate is used for compaction operation;

[0067] When the actual compaction degree is less than the standard compaction degree, a supplementary compaction operation is performed.

[0068] The asphalt pavement intelligent compaction method provided in the present embodiment obtains the functional relationship between the compaction degree, the number of rotary compaction times and the internal temperature of the asphalt mixture based on the indoor rotary compaction experiment through step S1, and establishes a first function; on this basis, obtains the functional relationship between the surface temperature and the internal temperature of the asphalt mixture through step S2 in the construction site experiment, and establishes a second function, thereby converting the internal temperature that is inconvenient to measure into the measured external temperature, and the external temperature can be associated with the compaction degree and the number of rotary compaction times; on this basis, substitutes the actual surface temperature of the asphalt mixture at the construction site into the second function through step S3 to obtain the actual internal temperature of the asphalt mixture, and substitutes the actual internal temperature into the first function to obtain the standard number of rotary compaction times when the compaction degree reaches the standard compaction degree; on this basis, obtains the standard rolling mill of the compaction machinery at the construction site through steps S4 and S5.

When the actual compaction degree is ≥ the standard compaction degree, the roller enters the next area for rolling, and when the actual compaction degree is < the standard compaction degree, the roller continues to perform additional rolling in the area. Through the mutual coordination of the above steps, the intelligent compaction method for asphalt pavement can effectively solve the problem of unreasonable compaction times in the existing asphalt pavement compaction method, thereby avoiding various diseases of the asphalt pavement in the later stage caused by unreasonable compaction times, ensuring the engineering quality of the asphalt pavement, and extending the service life of the asphalt pavement.

[0069] Specifically, a GNSS antenna is installed on the top of the roller to receive Beidou signals, obtain the current position of the roller in real time, and obtain speed signals, temperature, compaction data, etc. in real time, and express them in the form of cloud maps. When the compaction is sufficient, record the current position information and compaction, such as Figure 5In the red area, the roller moves to the next area for rolling. Figure 5 The blue area) is immediately alarmed, and the roller continues to perform additional rolling in the area. As the number of rolling times increases, the cumulative compaction value is continuously updated until the compaction meets the requirements. At the same time, the roller position information is combined with the cumulative compaction information in the form of a cloud map, such as Figures 5 to 8 The uncompacted area is detected and displayed on the vehicle terminal, and it is remotely transmitted to the server via GPRS signal (such as Fig. 9 shown).

[0103] Example 1

[0104] The asphalt mixture used in the asphalt pavement construction site of a certain section was subjected to indoor rotational compaction test to obtain the relationship between the number of rotations n and the compaction degree at different temperatures. Figure 2 As shown, we further fit the function compaction = f(n,T), and the fitting results and surfaces are shown in Figure 3 Based on the correlation between the existing asphalt mixture surface and the internal temperature of the mixture obtained by the insertion thermometer, the internal rolling temperature of the on-site asphalt mixture is converted to 160°C. At this temperature, the number of rotations when the compaction degree of the indoor rotary compaction test meets the standard is n1=140 times.

[0105] The fitting function expression is as follows:

[0106] P=f(n,T)=p00+p10×n+p01×T+p20×n2+p11×n×T+p02×T2+p30×n3+p21×n2×T+p12×n×T2+p03×T3(1);

[0107] p00=-75.62; p10=0.1059; p01=2.697;

[0108] p20=-0.008319; p11=0.006753; p02=-0.0166;

[0109] p30=5.627×10 -5 ; p21 = -2.335 × 10 -5 ; p12 = -1.225 × 10 -5 ;

[0110] p03=3.424×10 -5 .

[0111] The standard compaction rate of compaction machinery v1 = 3m / min was determined through the test section;

[0112] Based on the principle of energy equivalence under indoor and on-site construction conditions, namely: (Under the same temperature conditions)(2);

[0113] The on-site compaction mechanical rate v2 = 5 m / min is further determined, and is substituted into equation (2) to obtain n2 = 84 times. Then n2 and the temperature during on-site compaction T = 160°C are substituted into equation (1) as independent variables to obtain that the compaction degree is approximately 93% when the compaction mechanical rate is v2 under this temperature condition.

[0114] Example 2

[0115] During the compaction process of the asphalt pavement in a certain section, in order to realize the intelligent compaction of the asphalt pavement, a rate sensor and an infrared temperature sensor are installed at the front end of the roller to obtain the movement rate of the roller and the compaction temperature of the asphalt pavement surface in real time. Based on the correlation between the existing asphalt mixture surface and the internal temperature of the mixture obtained by the insertion thermometer, it is converted to its internal temperature T, and transmitted to the computer in real time through 5G network technology for calculation, and the compaction degree of the roller rolling area is calculated. It has been clearly stated on site that the compaction rate of the asphalt pavement under the standard compaction degree is v1=3m / min, and the current compaction rate is v2=5m / min. The compaction degree is calculated to be about 93% using the algorithm provided by the present invention. If it does not meet the standard requirements, an alarm will be immediately issued, and the current roller will immediately perform a re-compression operation so that its compaction degree meets the standard requirements, and then continue to move forward to complete the work in other areas to be compacted.

[0116] Example 3

[0117] During the compaction process of a certain section of asphalt pavement, in order to realize intelligent compaction of the asphalt pavement, the compaction rate of the asphalt pavement under the standard compaction degree has been clearly defined on site as v1=3m / min, and the current compaction rate v2=5m / min. The compaction degree calculated by the algorithm provided by the present invention is about 93%, which does not meet the standard requirements. Based on the existing data, the relationship between the compaction passes and the compaction degree under the current working conditions is fitted with a function, and the expression is: Y=4.2116ln(x)+90.349;

[0118] Among them, Y is the compaction degree and x is the number of compaction passes.

[0119] Then substitute the current compaction degree to determine that when the standard compaction degree reaches 98%, about 4 more rollings are required. The current roller will make up the compaction 4 times in time to meet the standard compaction degree, and then move on to other areas to be rolled to continue working.

[0120] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
