Importance of Geotextiles in Road Constructions & types of geotextiles

Do you know? Geotextiles are large sheets that save our earth soil in rainy days & binds strongly. It is mostly used for filtration and separation in the road constructions. It protects from migration of small gravels & sand aggregates. Geotextiles are thin & strong membrane fabric which is used to reinforce soil & prevent from damage.

Geotextiles are mostly used in road construction, especially to fill gaps between the roads to improve soil structure. Geotextile makes poor soil more beneficial for use and then easy to build in difficult places also.  Geotextile are ideal materials used for Construction & infrastructure like roads, buildings, dams and many more.

It improve & stability and decreases the process of wind & water erosion. It helps to prevent the erosion of soil but allows the water to drain off. A geotextiles made from synthetic or natural fibers associated with soil thin pieces. It improves soil characteristics such as Friction or movement restraint, Support of loads and Changes in bearing failure plane.

Function of Geotextiles

As per above explanation, hope you have got enough ideas about why we use geotextiles material. Depending upon many applications, geotextiles can be in Mesh types, wrap-knitted structure and other types of fabric surfaces like non-woven. Geotextiles can be used for the following areas lines, filtrations, drainage, reinforcement, sealing and protection.

Geotextile Applications

  1. For improvement of Paved & unpaved roads in airport roads
  2. On landfills and stone base courses
  3. For Land breaks filling with small geotextile portions.
  4. Beneath sidewalks and sand drainage layer
  5. Under the parking lots & curb areas.
  6. To enhance greenish environment and recreational facilities captured on beneath retaining wall structures
  7. Improving soil capping due to reinforce & pipe trenches

Types of Geotextile Membrane Fabrics:

Geotextiles are a polymers & synthetic made from textile materials named as polyester. The Geotextiles are effectively successful materials to improve road quality. It is divided into following types:

  1. Geotextile of Woven Fabrics
  2. Non-woven Fabrics
  3. Knitted Fabrics

Do you Want to know what exactly is Geotextile testing?

This is useful to check capabilities of textiles that will be helpful for Roads & highways. Some testing such as Direct shear test, Compressive creep properties, Tensile Creep and Creep Rupture Behavior, Resistance to perforation (Cone drop test), Trapezoid tearing strength, Grab tensile strength and more. To measure these behaviors and properties for geotextile, we use the following instruments for testing these purposes.

Following are suitable geotextile instrumentation range – In Aimil Ltd, we offers you the best of the kind instruments according to your need & applications:
