Analysis of Volumetric Properties of Bituminous Mixtures Using Cellular Phones and Image Processing Techniques
This study aims to develop the micro-analysis of the bituminous mixtures using Cellular Phone Images (CPI) and Image Processing Techniques (IPT). A new methodology and scheme was developed for faster and accurate procedure to compute volumetric design parameters; Voids in Mineral Aggregate (VMA), Voids in Total Mix (VTM) and Voids Filled with Asphalt (VFA) using CPI and IPT instead of the conventional methods. Five types of cellular phones with different high resolutions were used to analyze the horizontal cross section (face) of HMA slices. A cellular phone digital mapping frame for Micro-structure of the bituminous mixture for data collection was designed and implemented. New models for computations of volumetric design perimeters (VMA, VTM and VFA) were developed. Results showed that the best cellular phone for micro-analysis of the bituminous mixture is type D, even though it doesn’t have the highest resolution, and the best height of capturing the images is 35 cm.
