Rutting prediction of hot mix asphalt mixtures reinforced by ceramic fibers

One of the most severe problems with flexible asphalt pavements is permanent deformation in form rutting. Accordingly, practice adding fiber elements to mix improve performance under dynamic loading has grown significantly order prevent rutting distress and ensure a safe long-lasting road surface. This paper explores effects combination ceramic (CF), low-cost, easily available mineral fiber, thermal insulator reinforced enhance Marshall properties increase resistance mixes at high temperatures. Asphalt mixtures 0%, 0.75%, 1.5%, 2.25% CF content were prepared, stability wheel tracking tests employed study effect added on mixture performance. Scanning electron microscopy (SEM) field emission scanning (FESEM) also used investigate morphologies identify mechanism improvement .According results, ideal was which yielded an reduced rut depth by 22.05% 27.71% temperatures 50°C 60°C, respectively, when compared without CF. Microscopic analyses clearly revealed surface properties, particle diameter size, distribution mixture, including network structure strength mechanism, improved forming three-dimensional network.
