Determination of Compaction Parameters by Image Analysis Technique

Abstract

In this study, the control of compaction parameters for a stabilized filling material that is used in Granular Subbase (GSB) construction was examined by image analysis. Whether the specimen coming from the field met the GSB conditions was checked, and itsvoid ratio was examined by image analysis. For this process, the specimens that were prepared by mixing epoxy at different ratios were cut from a certain distance. Photographs were taken from the cut pieces using a SONY HSC-400 camera. For this purpose, specimens containing epoxy by 4%, 6%, 8%, and 10% were prepared. The ratios of the void found on the cut specimens were calculated. The void ratios that were calculated by using the eglobalformula and those calculated by image processing methods were compared, and the void ratio was determined at an accuracy rate of 86.12% for the specimen that contained epoxy at a ratio of 8%.
