Asphalt quality rapid detection and monitoring method and device and storage medium

Abstract

The invention discloses a rapid asphalt quality detection and monitoring method and device and a storage medium. The method comprises the following steps: creating a standard infrared spectrogram database of a standard asphalt sample; acquiring a first detection infrared spectrogram of a to-be-detected asphalt sample; obtaining a first detection result of the detected asphalt sample according to the standard infrared spectrogram database and the first detection infrared spectrogram; dividing the to-be-detected asphalt sample to obtain to-be-detected asphalt sub-samples; acquiring a second detection infrared spectrogram of the detected asphalt sub-sample; obtaining a second detection result of the detected asphalt sub-sample according to the standard infrared spectrogram database and the second detection infrared spectrogram; judging whether the difference between the first detection result and the second detection result is within a preset difference range or not; if yes, outputting a detection quality qualification result; and if not, outputting a result that the detection quality is unqualified. The method is high in detection efficiency and accurate in monitoring result.

Description

technical field [0001] The invention belongs to the technical field of asphalt quality detection, and in particular relates to a rapid detection and monitoring method, device and storage medium of asphalt quality. Background technique [0002] Asphalt is an important part of highway pavement materials, and its quality directly affects the service life of the pavement, operating costs, and driver comfort. Therefore, rapid detection and monitoring of asphalt quality during road construction and operation is the key important means. [0003] Traditional asphalt detection and monitoring methods are not only time-consuming and labor-intensive, but also easily affected by additives such as modifiers and stabilizers, and the test results are easily distorted; due to the complexity of the chemical properties of asphalt, the asphalt specification has developed tests for physical properties, such as Penetration softening point, ductility performance testing and other tests, these phy...

[0003] Traditional asphalt detection and monitoring methods are not only time-consuming and labor-intensive, but also easily affected by additives such as modifiers and stabilizers, and the test results are easily distorted; due to the complexity of the chemical properties of asphalt, the asphalt specification has developed tests for physical properties, such as Penetration softening point, ductility performance testing and other tests, these physical property tests are carried out at the standard test temperature, and the test results are used to determine whether the material meets the standards of the specification

[0004] Evaluating the quality of asphalt using three major indicators is a traditional testing method for judging the performance of asphalt. It is also the main method for testing asphalt in the highway industry. However, the traditional testing method has many limitations and cannot fully identify and fully reflect the performance of asphalt.
