Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0050] The basic idea of ​​the present invention is: collect the data of the asphalt mixture to obtain the collected image; perform image processing on the collected image to obtain the content of each component of the asphalt mixture. Among them, the content of each component of the asphalt mixture specifically includes: the volume composition of asphalt, voids, and aggregates in the asphalt mixture, and the volume composition of aggregate particles of various particle sizes in the aggregate, and the composition relationship can be displayed by three-dimensional graphics.

[0051] In the specific implementation, the data collection of asphalt mixture can be taken by a digital camera or a special image acquisition camera to obtain the collected imag...

Abstract

The invention discloses a detection method of bituminous mixture, including the following steps: digital image collection of bituminous mixture is completed; image processing of the acquired digital image is completed to obtain the content of compositions of the bituminous mixture. Moreover, the invention also discloses a detection system for the bituminous mixture. Both the method and the system can complete effective separation and extraction of bitumen, airgap, aggregate and aggregate particle of different particle diameter and realize direct determination and calculation of volumetric composition characteristic parameter of the bituminous mixture through converting the obtained characteristic parameter into volume ratio; moreover, the invention improves the mechanical property of the bituminous mixture and provides reliable basis for the scientificity in bituminous pavement engineering research.

Description

technical field [0001] The invention relates to asphalt mixture testing technology, in particular to a detection method and detection system of asphalt mixture. Background technique [0002] With the rapid development of my country's economic construction, highway construction has also entered an unprecedented stage of development. The relationship between people's life, production and road transportation is getting closer and closer. Good road surface quality can effectively promote economic development and improve people's production and living standards. As the main structural form of highway construction, asphalt pavement has been widely researched and applied in highway construction. [0003] Asphalt pavement is composed of asphalt mixture, which includes asphalt, voids and aggregates, and aggregates include mineral materials of different particle sizes. The quality of asphalt pavement prepared by the distribution scheme of different components of asphalt mixture is d...
