Laboratory evaluation of combined effect of jute fibres and rejuvenators on some performance characteristics of asphalt mixture containing reclaimed asphalt

Popis výsledku v původním jazyce

The use of reclaimed asphalt (RA) in asphalt concrete mixtures have achieved economic and environmental benefits and it is important when we want to get in line with sustainable development and circular economy. This paper aims to evaluate the effectiveness of the addition of two bio-based rejuvenators and jute fibres on the performance of asphalt mixture designed with 30% by mass RA content. Seven mix variants, varying with the addition of the rejuvenator and/or fibres, were analysed. Mechanical performance was evaluated through laboratory tests measuring moisture susceptibility (ITSR), stiffness modulus (IT-CY), resistance to crack propagation (SCB) and dynamic modulus (4PB-PR). Mixtures with jute fibres showed lower ITSR. In comparison with the reference mixture, a decrease in the stiffness modulus has been shown for mixtures with rejuvenators. Opposite trend was observed when fibres were added. Best performance in resistance to crack propagation and complex modulus was achieved by adding jute fibres with rejuvenator to the mixture.
