QUANTITATIVE STUDY OF BITUMINOUS MATERIALS MICROSTRUCTURE BY DIGITAL IMAGE ANALYSIS
The objective of this paper is to develop a quantitative characterisation of grading curves by the use of image analysis. Usually, survey methods are based on the use of chemical solvents or ignition to separate the mineral phase and the organic phase. Actually, laboratories mostly use these methods over the world to determine composition of bituminous mixes. This approach is reliable and fast but meets some problems with particular constituents and does not give the spatial distribution of constituents. The aim of the research work is to study the internal structure of the bituminous material (composition and distribution) from image analysis of sample surface. For example, it is possible to determine accurately the grading curve of the bituminous mixes with digital image processing. A comparative study of grading curves from different plane cross-sections of a sample is presented. The results obtained with this new method highlighted the importance of using image analysis to determine composition of bituminous mixes and anisotropy measures without using chemical solvents. Results of the well known analyses in materials science are used for showing the possible extension of this approach to road material. For the covering abstract see ITRD E121480.
