Mullen Burst ASTM D3786 and Puncture D4833 will be removed from Product Data Sheets on January 1, 2010. Neither test method is recognized by AASHTO M288. CBR puncture D6241 has replaced D4833, under AASHTO M288. Mullen Burst is not recognized by D35 committee on Geosynthetics. For more information, please see Geosynthetics magazine.

Civil Nonwovens


Functions

Filtration: Civil nonwoven geotextiles filter soil particles while allowing excellent water permittivity for structures requiring drainage.

Erosion Control: They can provide erosion control structures with stabilization and filtration.

Reinforcement / Stabilization: They can improve the mechanical properties of soil and structural fill by absorbing tensile forces and reducing deformation.

Separation: They also perform separation beneath roads, keeping dissimilar materials separated to maintain their functionality.

Drainage: Their high in-place and normal flow rates prevent excess water buildup and pore pressure, keeping civil structures strong and stable.

Product Description

Thrace-LINQ civil nonwoven geotextiles are designed for high permittivity (water flow) and a fine pore structure. Their strength prevents damage due to construction stresses, while their pores allow the free flow of groundwater and in-place gas and liquid transmission. Given their fine pore structure, civil nonwovens prevent fine soils from piping through or clogging the geotextile - eliminating the need for an expensive graded granular filter.

AASHTO M 288 is the national guideline specification for the use of geotextiles in civil engineering applications. Thrace-LINQ civil nonwovens meet the guidelines as follows:

  • 140EX: Class 3 Drainage, Separation and Stabilization; Paving Fabric
  • 150EX: Class 2 Drainage, Separation and Stabilization
  • 180EX: Class 1 Stabilization and Permanent Erosion Control

Features & Benefits

  • Nonwoven structure, providing excellent surface friction and built-in elongation
  • Effective filter, with tight pore size (AOS=70) and high permittivity
  • High tensile strength, with excellent puncture and tear resistance
  • Range from 3.2 oz/sy (109g/sm) - 16.0 oz/sy (543g/sm)
  • Thick structure, allowing cushioning and lateral gas and liquid transmission
