Abstract:
All existing roads, even the best made and designed ones, become deteriorated over time, mainly because of traffic loading and severe weather conditions. In the move to raise the aim of advancing the basic bitumen performances, many blends with various modifiers have been analyzed and studied by researchers. Optimal bitumen content analysis is the principal objective with foamed bitumen mixture design. Conversely, bitumen mix design methodologies with foamed bitumen are still under investigation. In this paper, an integral way of determining the optimal bitumen compositions in terms of their specific gravity at room temperature (25oC) has been developed with a model. The model [Bitumen quantity (mg) = 52162 (specific gravity) + 5.061] at R2 of 0.9990. This model could enable the bitumen contents value for estimation before the experimental and field applications as it gives a clear direction to touch of refinement meeting the technical requirements. This approach is anticipated to reduce resources for time and materials that may be required during the mix design procedure. However, experimental validations are suggested at the initial stage of the analysis.
