Abstract
An analysis of physical, hydraulic and mechanic properties of nonwoven needle-punched geotextiles An analysis of physical, hydraulic and mechanic properties of needle-punched nonwoven geotextiles. This paper presents an analysis of technical parameters of needle-punched geotextiles used in engineering constructions. The tests were carried out in order to compare of physical, hydraulic and mechanic properties of needle-punched geotextiles in two different groups of products. First of group, geotextiles, were made of polypropylene fibers (PP) and the second one fabrics, were of polyester filaments (PES). The tests were performed for materials of mass per unit area 250, 400 and 600 g/m2. The results of test showed that parameters of geotextile material depend on structure of fabrics.
