Embodiment Construction

[0025] The present invention relates to a geotextile comprising a plain weave six pick weave fabric. Such fabrics can be used for soil reinforcement in civil structures such as unpaved or paved roads, runways, building foundations, and the like.

[0026] For a fuller understanding of this disclosure and the invention described therein, reference should be made to the foregoing and following detailed description and accompanying drawings. In referring to the drawings, like reference numerals indicate corresponding parts throughout the several views.

[0027] refer to Figure 1 to Figure 4 , illustrates a woven geotextile 10 comprising a plain weave six pick fabric 11 . The fabric 11 has an apparent open size (AOS) of at least 40 as measured according to ASTM International Standard D4751 and a water flow rate of at least 35 gpm / ft measured according to ASTM International Standard D4491 2 , and a 12% strain tensile load of at least 300 lbs / in measured in the warp direction acc...

Abstract

Described herein is woven geotextile formed of a plain six-pick weave fabric having an apparent opening size (AOS) of at least 40 as measured in accordance with ASTM International Standard D4751, a water flow rate of at least 35 gpm / ft2 as measured in accordance with ASTM International Standard D4491, a 12% strain at a tensile load of at least 300 lb / in as measured in accordance with ASTM International Standard D4595 in the warp direction, and a 12% strain at a tensile load of at least 270 lb / in in accordance with ASTM International D4595 at 270 lb / in in the fill direction. Also described herein is a reinforced civil structure having a subgrade formed at least partially of soil; a base course; and a woven geotextile disposed between the subgrade and the base course.

Description

technical field [0001] The present invention relates generally to geotextiles. More particularly, the present invention relates to geosynthetic fabrics having high water flow and small particle retention capabilities and their use in civil structures. Background technique [0002] A variety of geotextiles are used in erosion control, turf reinforcement, and civil structures (including soil reinforcement). Geotextiles employed in soil reinforcement of hierarchical and graded structures (e.g., roads or runways, and foundations) typically have greater biaxial geotextile tensile and / or shear than those employed in erosion control and turf reinforcement. shear strength properties. Additionally, geotextiles used in soil reinforcement applications have greater symmetrical tensile and / or shear strength properties than soil reinforcement materials employed in retaining wall structures and steep slopes. Consequently, these flatter, more biaxial, and less aggressive environments ind...
