Two-dimensional internal structure detection system of asphalt mixture and detection method

Abstract

The invention relates to a two-dimensional internal structure detection system of an asphalt mixture and a detection method. The system comprises a document management module, an image preprocessing module, an aggregate grading screening identification module, and an internal structure characteristic index calculation module, wherein the document management module, the image preprocessing module,the aggregate grading screening identification module, and the internal structure characteristic index calculation module are connected in sequence. The system has the advantages of high test accuracy, simple operation and low cost, overcoming defects of a traditional mixture internal structure test method describing overall characteristic of the internal structure through a single evaluation index. The system and method reflect distribution of internal components of the asphalt mixture in specific aspects, and evaluate overall characteristic and distribution characteristic of internal structure of the asphalt mixture accurately and objectively, thereby being low-cost, easy-to-promote novel test and evaluation system and method.

Description

technical field [0001] The invention relates to the field of internal structure detection of asphalt mixture, in particular to a two-dimensional internal structure detection system and detection method of asphalt mixture. Background technique [0002] Asphalt mixture is a typical multiphase mixture. The distribution of coarse aggregate, asphalt mortar and voids in the mixture directly affects the pavement performance. How to accurately evaluate the internal structure of asphalt mixture is the key to the study of asphalt pavement performance. [0003] Stereology is a new discipline between morphology and mathematics. Its core idea is to quantify Characterize and describe actual tissues. Any three-dimensional object can be regarded as composed of infinitely many parallel slices. Although it is impossible to rely on a single section to judge effective three-dimensional object information, the two-dimensional object information contained in these infinitely many slices forms a ...
