Analysis of flexible pavement materials with image analyzer

Umar, Tariq; Wamuziri, Sam Chris

Abstract

Future demand to study and understand properties of flexible pavement materials to enhance its performance and durability and to increase its life is huge. Keeping these points in mind, this study presents the work to assess the distribution of asphalt in different types of asphalt concrete using image analysis software. A total of 12 cores obtained from different area and having different composition, comprising of 48 slices and 72 images were analysed with a computer image analyser to ascertain distribution of aggregates and asphalt. Finally, study is made of variations between aggregates/ asphalt ratio with unit weight of slice to investigate a relation. There was, however, no valid relation between these values which can tend to a strong conclusion except technique used for the study is easy, time saving and do not need high skill. This matter can be further investigated with computer software which can possibly analyse the images and can extract true area of different colours from images. As the result image analysis technique for different types of asphalt mixes including one with vegetable oil were almost same, therefore in this work it is concluded that there will be less effect on physical properties of asphalt mixtures prepared with some amount of vegetable oil.
