THE DEVELOPMENT OF A COMPUTER CONTROLLED IMAGE ANALYSIS SYSTEM FOR MEASURING AGGREGATE SHAPE PROPERTIES

摘要: This Innovations Deserving Exploratory Analysis (IDEA) project developed and tested a prototype of an automated image analysis system for measuring aggregate shape characteristics. A review available methods analyzing features was performed procedure texture developed. software that incorporated several procedures applied to measure the wide range fine coarse aggregates. work followed by efforts develop hardware system. The computer-controlled mechanism allow capturing different projections particles describing their properties rapidly accurately. user-friendly version also facilitate data presentation manipulation. were integrated produce on aggregates results compared with hot mix asphalt performance data. found provide detailed information in short time. measurements showed good correlation resistance mixes permanent deformation measured laboratory using wheel tracking devices.
