Resistance of Geotextiles Against the Isolated and Combined Effect of Mechanical Damage Under Repeated Loading and Abrasion

摘要：

　　The installation procedures(which may cause mechanical damage)and abrasion may provoke unwanted changes in the properties of the geosynthetics,affecting their performance.This work evaluated the resistance of two geotextiles(with different structures)against two degradation mechanisms: mechanical damage under repeated loading and abrasion.The geotextiles were(1)exposed in isolation to each degradation mechanism and(2)exposed consecutively to both degradation mechanisms.The damage suffered by the geotextiles(in the degradation tests)was evaluated by monitoring changes in their tensile and static puncture behaviour.Based on the changes occurred in tensile and puncture strength,reduction factors were determined.The reduction factors obtained in the successive exposure to mechanical damage under repeated loading and abrasion were compared with the reduction factors determined by the traditional methodology for the combined effect of those degradation mechanisms.
