Evaluation of the mechanical performance of AC mixtures with recycled fibres

Based on the positive results of most of the studies using virgin fibres to reinforce asphalt mixes, this work proposes the use of recycled fibres in order to go a step further in terms of environmental impact and cost-efficiency. Different experimental asphalt concrete (AC) mixtures are proposed, i...
