ABSTRACT
Asphalt reinforcement products manufactured using polyester fibres have successfully been applied in pavement rehabilitation for more than 40 years. Their outstanding performance has helped to increase maintenance periods, which provides a substantial financial cost saving but also a very positive ecological effect, in form of a reduction in the use of exhaustible resources and reduced traffic disruption.
This performance history impressively highlights the application of asphalt reinforcement.
A number of factors which influence the performance of an effective asphalt reinforcement have been identified. Recent research has focused on a couple of these influence factors which are summarized in this paper.
Surface characteristics of the raw material and their effect on the in-situ activated tensile strength
Elongation underneath the asphalt layer during dynamic loading and the influence on lifetime expectation
A cost comparison between the rehabilitation methods is given as well as a detailed description of the calculation of CO2 emissions.
