Abstract:
This study aims to develop the microanalysis 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 camera resolutions were used
to analyze the horizontal cross section (face) of hot mix asphalt slices. A cellular phone digital mapping frame for microstructure
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 microanalysis of the bituminous
mixture is type D, even though it does not have the highest resolution, and the best height of capturing the images is 35 cm.
