Description

Technical Field

[0001] The invention relates to a luminous pavement acceptance method, in particular to a luminous pavement acceptance method prepared from a long afterglow luminescent material. Background Art

[0002] In addition to meeting basic functions, current urban trails are also required to have additional functions such as safety, comfort, aesthetics and environmental protection. This is a higher requirement for the functionality of urban trails. Luminous natural color pavement came into being under this background. Luminous pavement has received widespread attention as a new means of urban beautification and safety improvement.

[0003] At present, the realization of luminous pavement mainly relies on adding luminous powder to pavement materials or using luminous paint. At present, luminous pavement technology is in its infancy, with little engineering practice, and the industry has not yet formulated relevant standards or specifications for the design, construction and acceptance of luminous pavements, which to some extent hinders the promotion and application of luminous pavement technology.

[0004] The existing technical solutions lack effective acceptance standards and methods, making it difficult to ensure the quality of luminous pavements. The performance evaluation of luminous pavements mostly remains at the subjective evaluation level, lacking objective and scientific quantitative indicators. The traditional pavement evaluation index system cannot objectively evaluate the performance of luminous pavements. Chinese patent document CN202110723501.2 provides a pouring asphalt concrete luminous pavement paving technology, which mixes silicate luminous materials with pouring asphalt concrete and then paves it on the park pavement, effectively ensuring the luminous intensity of the pavement, improving the aging resistance, and extending the service life of the pavement. However, the patent does not involve the acceptance standards and acceptance methods of the pavement, and lacks corresponding references for the control of the quality of pavement engineering.

[0005] Therefore, it is necessary to provide a method for accepting luminous pavement made of long afterglow luminescent materials. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a method for accepting luminous pavement made of long afterglow luminescent materials. The method is simple to operate and has strong scalability. It can carry out a comprehensive assessment of the quality of luminous pavement projects. The acceptance process does not cause physical damage to the pavement, and the method can be used for the acceptance of luminous pavement projects.

[0007] The technical solution adopted by the present invention to solve the above-mentioned technical problems is to provide a method for accepting luminous pavement made of long-afterglow luminescent materials, comprising the following steps: S10: using long-afterglow luminescent materials as fluorescent powder to pave the luminous pavement; S20: detecting the luminous chromaticity coordinates of the luminous pavement and the luminous chromaticity coordinates of the raw materials of the fluorescent powder; S30: detecting the luminous intensity of the luminous pavement and the luminous intensity value of the raw materials of the fluorescent powder; S40: using the comparison values ​​of the chromaticity coordinates and the luminous intensity before and after the paving of the fluorescent powder to implement the acceptance evaluation of the luminous pavement.

[0008] Furthermore, the step S10 includes: evenly mixing the fluorescent powder, binder, mineral powder, stone, and curing agent in a preset proportion to obtain a luminous pavement mixture, and evenly paving the luminous pavement mixture on the planned ground.

[0009] Furthermore, the binder is a transparent binder with a transparency greater than 95%.

[0010] Furthermore, the step S20 uses a colorimeter to perform measurement, and obtains the luminous chromaticity coordinates of the luminous pavement and the fluorescent powder by comparing with the synthetic pigment.

[0011] Furthermore, the step S30 uses a light meter to measure the luminous intensity of the luminous road surface and the fluorescent powder, and the measurement range is 500~1000cd / m².

[0012] Furthermore, the step S40 includes: if the luminous chromaticity coordinates of the paved luminous pavement and the fluorescent raw material are located in the same color area; compared with the fluorescent raw material, the luminous intensity attenuation percentage of the paved luminous pavement does not exceed a preset threshold; and at the same time, the maximum gap of the luminous pavement is detected to be less than the value specified in the specification, and the anti-skid performance friction coefficient swing value is greater than the value specified in the specification, then the luminous pavement is judged to be qualified for acceptance.

[0013] Furthermore, the preset threshold value of the luminous intensity attenuation percentage is 10%, the specified value of the maximum gap is 5 mm, and the specified value of the anti-slip performance friction coefficient swing value is 35.

[0014] Furthermore, the number of luminous chromaticity coordinate tests is 5 points / kilometer, and the number of luminous intensity value tests is 10 points / kilometer.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. It provides an objective and scientific basis for the acceptance of luminous pavement, formulates a complete set of acceptance standards and methods, and provides reliable technical support for the quality control of luminous pavement. 2. It promotes the standardized development of luminous pavement technology. The implementation of the present invention is conducive to promoting the technological progress and standardized management of the luminous pavement industry. 3. It can provide ideas for the maintenance and inspection of luminous pavement. 4. The pavement acceptance method provided by the present invention will not cause damage or pollution to the pavement during the acceptance process, and can be inspected multiple times during the use of the pavement.

Preferably, the luminous powder in step S10 is a long afterglow luminescent material, and the binder is a transparent binder with a transparency greater than 95%. After mixing with the stone, it can well present the color of the stone itself, avoiding the luminescence of the fluorescent powder after mixing.

[0021] Preferably, the colorimeter instrument in step S20 refers to a laboratory instrument that measures or specifies color by comparison with synthetic pigments, and can accurately test the luminous chromaticity coordinates of fluorescent powder or luminous pavement.

[0022] Preferably, the light meter instrument in step S30 is a fluorescent powder or luminous road surface luminous intensity testing instrument, and its measurement range is 500~1000cd / m².

[0023] Preferably, the specific method of step S40 is to control the luminous intensity attenuation percentage of the luminous pavement after paving with the same concentration of fluorescent powder to not exceed 10%, the chromaticity coordinates of the fluorescent powder raw materials do not change before and after paving, and the road surface flatness, anti-skid ability and other indicators should comply with the provisions of the specification "Technical Specifications for Highway Asphalt Pavement Construction" JTG F40-2004.

The specific results are shown in Table 1 below; Table 1 Chromaticity coordinate test results S30: using a light meter to test the luminous intensity of the paved luminous road surface and the luminous intensity of the raw materials of the fluorescent powder, the results are shown in Table 2 below; Table 2 Luminous intensity test results S40: According to the results in Table 1 and Table 2, the chromaticity coordinate index of the project meets the expected requirements. The chromaticity coordinates of the five points are consistent with the chromaticity coordinates of the raw materials, and no abnormalities occur; the luminous intensity value of the road surface of the project is between 700-900cd / m², which meets the expected requirements, and compared with the raw materials of the phosphor, the luminous intensity attenuation rate of the phosphor after being paved into the road surface is less than 10%, which meets the expected requirements; at the same time, the flatness index (maximum gap) of the project is 3mm, which is less than the maximum index requirement of 5mm specified in the specification, and the anti-skid performance friction coefficient swing value (BPN) result is 65, which meets the specification requirements. The road surface acceptance result is passed and can be opened to traffic.
