Glass fiber reinforced asphalt paving mixture : feasibility assessment

Abstract EN

The development of different asphalt additives and modifiers requires that pavement engineers make sound judgment regarding the effectiveness of these new products in order to justify their use.

Therefore, informing the pavement engineers in recent materials development along with a method to assess the feasibility of using the new products is essential.

This paper presents a performance based economical assessment regarding the feasibility of reinforcing the asphalt paving mixture using glass-fiber, taking into consideration factors such as initial construction cost, major rehabilitation, and salvage value of the pavement at the end of the analysis period.

The result of this study shows that reinforcing the asphalt paving mixture with glass-fiber enhances the overall performance of the pavement structure.

Such improvement would reduce future rehabilitation cost thus making the use of the reinforced paving mixture more economical.
