Abstract

A new bridge scour countermeasure using geobags and recycled aggregates which is more stable and economical than existing methods is proposed, and its stability was verified through material tests. PP short staple nonwoven geotextile and PET long staple nonwoven geotextile produced in Korea were selected, and a series of strength tests and a test of hydraulic characteristics were conducted to determine a suitable geotextile for geobags. A series of leaching test was also conducted to assess the potential environmental risk of recycled concrete produced in Korea when it is utilized as a material for protecting bridge piers against scour.
