Article Synopsis
- This study assesses the potential of using coal ash in asphalt mixes by examining its physical and chemical properties using various analytical techniques like SEM and XRD.
- The research compares asphalt mixes made with coal ash to traditional gneissic aggregates, focusing on their compaction, water resistance, and rutting performance.
- Findings suggest that coal ash can be technically feasible for use in asphalt formulations, despite exhibiting inert and hydrophilic properties similar to gneissic fillers.
This paper discusses the importance of studies on materials known as fillers from different mineral origins, used in asphalt mixes, specifically in the formulation of mastics. The research was carried out on samples of limestone and granite rock filler and asphalt binder (50/70). The samples were evaluated through semiquantitative chemical analyses by X-ray fluorescence, granulometry by low angle laser emission, scanning electron microscopy, softening point tests, penetration tests, and aggregate-asphalt binder and aggregate-mastic adhesion tests.
