MECHANICAL PROPERTIES OF POLYESTER GEOTEXTILES AFTER ONE YEAR AGING IN ALKALINE MEDIUM

Abstract

This study consists in assessing evolutions of the mechanical
characteristics of geotextiles used for reinforcement application
during ageing in moderately alkaline medium (pH 9-11). The
analyzed geotextiles consist of polyethylene terephthalate woven
fibres. By correlation between the mechanical properties usually
used as indicator of ageing and the physico-chemical properties
on various scales of as-received materials and aged for one year
in laboratory, the understanding of the behaviour of degradation
could be improved
