Abstract:
The poor performance of pavement as well as the short life time of pavement is caused by misused of bitumen and materials and inappropriate mixture of asphalt. To achieve optimum performance of pavements with proper and harmonious development of all the above factors are needed. Since bitumen is sensitive to high temperature and in order to prevent damages caused by high temperature, the classic tests and using additives is important. This causes the behavior ultimately leads to modified bitumen asphalt mixture performance. In this research the effects of different percentages of glass fiber on properties of pure bitumen are performed. The results show that glass fiber causes increasing in ductility, softening point and penetration test of bitumen. Due to positive obtained results it is suggested to use the glass fiber as an additive to bitumen.
