This technical report explores the use of ACE XP aramid fibre as a reinforcement technology in asphalt pavement design. Inforce collaborated with Optim Consultants to create a detailed report for those exploring the benefits of ACE XP. These Aramid fibres, derived from aromatic polyamides, offer exceptional thermal stability, tensile strength, and chemical resistance, making them ideal for improving asphalt performance and durability. Unlike conventional cellulose fibres, aramid fibres contribute structurally, enhancing stiffness, fatigue life, and rutting resistance without altering mix design parameters.
The document outlines key properties of aramid fibres, dosage recommendations, and their integration into pavement design software such as CIRCLY. It also presents comparative performance data, adjustment guidelines for stiffness and fatigue constants. Practical design examples demonstrating benefits like extended pavement life, reduced cracking, and potential thickness optimization. This report serves as a guide for engineers seeking to optimize high-performance asphalt pavements with confidence.
