| Because of their high initial properties, aramid geotextiles have been used for a decade for ground reinforcement. Today, the geotextiles manufacturers think about their use in alkaline grounds. However there are few data on the long-term behaviour of aramid fibres under these conditions. Consequently, a durability study in a basic environment has been carried out in order to improve understanding of the degradation mechanisms involved in ageing. On that purpose, the physico-chemical characteristics as well as the surface state and the mechanical properties of the Twaron 1000 fibres have been followed at different ageing times. |
