Screening method for recycled asphalt concrete production

Abstract

The invention relates to the technical field of artificial intelligence, in particular to a screening method for recycled asphalt concrete production. Acquiring plane images of different batches of asphalt concrete to obtain corresponding feature descriptors; obtaining an optimal screening mode of the asphalt concrete of each batch based on the screening quality evaluation index, and forming a feature vector of the asphalt concrete of the corresponding batch by the optimal screening mode and the optimal screening quality evaluation index; and grouping the feature vectors to obtain a general screening mode of each group, performing similarity calculation on the real-time feature descriptor of the to-be-screened asphalt concrete and the feature descriptor corresponding to each group, and obtaining an optimal general screening mode according to the similarity to serve as a screening method of the to-be-screened asphalt concrete. The image features of the to-be-screened asphalt concrete are extracted, and the corresponding optimal screening mode is intelligently recognized, so that the screening quality is effectively improved, and the screening speed is effectively increased.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a screening method for producing recycled asphalt concrete. Background technique [0002] During the renovation and reconstruction of waste asphalt concrete pavement, a large amount of asphalt concrete aggregate will be produced. These old materials still have high use value as road materials. In the treatment of these old materials, screening after crushing is one of them. It is an important process, but due to the aging degree of the road surface and the condition of the crusher, the crushing quality of the asphalt concrete aggregate is also different, which directly affects the screening quality and screening speed of the asphalt concrete aggregate. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a kind of screening method for the production of recycled asphalt conc...
