Abstract

Glass fibers were used to investigate the impact of loose fiber reinforcement on the performance characteristics of"br" asphalt mixtures. For the laboratory tests on asphalt mixes a fiber content of 0.5 mass.-% was chosen. This paper"br" presents selected results of fatigue, stiffness (both cyclic indirect tensile tests) and rutting / plastic deformation"br" tests (cyclic uniaxial compression test) on different asphalt mixes. An asphalt base course mix AC 22 T S, an"br" asphalt binder course mix AC 16 B S and an asphalt concrete AC 8 D S were chosen to determine the effect of"br" glass fiber reinforcement. Furthermore, the fiber length was varied for the AC 16 B S. The content of reclaimed"br" asphalt (RA) was varied for the AC 22 T S. Depending on the mix design the bitumen content was increased up"br" to 0.3 mass.-%.
