Abstract

This study assesses the application of the simple Digital Image Correlation (DIC) technique as an addition to the qualitative-based boiling water test to quantify the stripping phenomenon on a bituminous mixture, as the mixture was modified by ethylene-vinyl acetate (EVA) to enhance its stripping resistance. A mini photo-box model was created to ensure the uniformity of the lighting for a good-quality image captured by a camera phone, and the results were compared using a variety of thresholds to the weighing scale to ensure the accuracy of the method. It was found that the ImageJ software used could give outcomes matching the actual condition based on weighing when the threshold was set to 70, and the use of polymer could reduce the stripping ratio from 21.85% to 14.05%, with the error margin with DIC software analysis of up to 13% and the average difference of 6%. Overall, the image correlation technique can be used to characterise the stripping phenomenon on asphaltic mixtures, and the inclusion of polymer could enhance the stripping resistance of the mixture with the maximum increase reached by the polymer dosage of 5%.
