Özet

In this study, the usability of basalt fibers in order to bear the stresses occurring at the surface layer of pavement, which are directly subjected to the traffic effects, was investigated. In this context, specimens were produced and tested under Marshall Stability Test, and the optimum bitumen content value for the aggregates sample to be used was determined. Based on the determined value for the optimum bitumen content (5%), three specimens for each of a series of different fiber ratios were prepared. The optimum value for fiber ratio that results in the best stability value was determined. In order to determine whether the best fiber ratio (0.50%) might result in a better stability value for other bitumen contents, extra specimens were prepared with different bitumen amounts and with the best and five different fiber ratio values close to the optimum value. These specimens were tested under Marshall Stability Test and the obtained results were evaluated. (C) 2013 Elsevier Ltd. All rights reserved.
