THE INFLUENCE TO THE MECHANICAL PROPERTIES OF BITUMINOUS MASTICS AND, THUS TO OPEN GRAIN ASPHALT USING SYNTHETIC FIBRES

This paper deals with the influence of synthetic fibres on the properties of hot mix asphalt and specifically to open graded asphalt. It includes an 8-year field study case on an asphalt road in Austria. The Austrian road report provides substantial evidence that specific fibres not only inhibit binder drain off, but also considers synthetic fibres as a further alternative to modify bitumen, enhance the engineering performance of the mastic and thus, the overall long-term cost effective performance of asphalt. Restrictive budgeting by governing authorities means that the design of asphalt mixes by pavement engineers will require more innovation; additive synthetic acrylic fibers are a solution.
