Microsurfacing suspended fibre technology: product innovation: laboratory research investigation

Road network maintenance strategies increasingly demand more from road surfacing applications for every dollar spent. This demand requires the development of innovative ways to get more performance from our current products. Microsurfacing offers pavement asset managers a cost effective maintenance application that can extend asset life cycles. A well identified constraint however of a standard microsurfacing has been its limited performance with regard to its resistance to reflective cracking from existing pavement surface cracks. The result of an extensive research and development project spanning over 5 years microsurfacing SFT (Suspended Fibre Technology), has been developed aimed specifically at enhancing the performance of standard microsurfacing in relation to flexibility, to resist reflective crack development and increasing modulus strength properties. Microsurfacing SFT meets and exceeds all standard microsurfacing specifications and is shown to increase the performance for flexibility and modulus strength up to 50 per cent when compared to standard microsurfacing applications, to provide a high performance, cost effective paving material.
