...-filament polyester (PET) geotextile, and on two nonwoven needle-punched polypropylene (PP) geotextiles with carbon black in Vijus, Peru, and Atlanta, Georgia, USA. The average retained strengths of each geotextile in both locations did not exceed 60%. Five geotextile samples (those previously mentioned...

...D.G. Grubb; W.E. Diesing, III; S.C.J. Cheng; R.M. Sabanas Outdoor exposure tests were completed on two woven slit-film polypropylene geotextiles with carbon black and two nonwoven needle-punched polyester geotextiles in Huaron (∼11°S; 4,600 m elevation) and Vijus (∼7°45′S; 1,250 m elevation), Peru...

...R. Kumar; V.K. Kanaujia; D. Chandra This note presents the results of laboratory investigations conducted on silty sand and pond ash specimens reinforced with randomly distributed polyester fibres. The test results reveal that the inclusion of fibres in soils increases the peak compressive strength...

... of geosynthetics. To assess the durability of polyester (PET) geosynthetics, an accelerated testing protocol was developed and a test program implemented. The test results indicated that low-tenacity PET commercial geosynthetic products were more susceptible to hydrolytic degradation than high-tenacity...

...S.F. Barrington; K. El Moueddeb; J. Jazestani; M. Dussault Three different types of heat-bonded, needle-punched, nonwoven polyester geotextile specimens with similar hydraulic conductivities, but with different O₉₀ values and average pore opening sizes, were exposed...

...S.C.R. Lo The pull-out resistance of a high tenacity polyester strap at a low overburden stress of less than 100 kPa was studied with a large-scale pull-out box. Three different types of soil hauled from active construction sites were used. The test results indicated that the friction factor...
