Laboratory and field characterisations of fibre-reinforced porous asphalt: a Dutch case study

Abstract: A European research project named FIBRA (2017-2021) has been conducted under the Conference of European Directors of Roads (CEDR) on fostering the implementation of fibre-reinforced asphalt mixtures by ensuring its safe, optimised and cost-efficient use. This paper presents a Dutch case study on demonstration of a fibre-reinforced PA 8, top layers of two layer porous asphalt, on Dutch motorway A73. The results indicate that PA 8 can be reinforced using both polyacrylonitrile and aramid fibres instead of polymer modification through evaluation of lab performance, production process and initial pavement performance. The addition of fibres may contribute positively to the strength of the mixture, the stiffness and possibly aging resistance of the mortar. The workability of fibre-reinforced PA 8 is better than that with polymer modification. The accelerated load testing results indicate that the PA 8 with fibre reinforcement has an expected service life similar to that with polymer modification.
