Role of geotextile: This presentation highlights the potential market for geotextile in Pakistan. Recent floods and earthquakes have highlighted the urgent need to make better road networks and use of Geotextile can enhance the performance of road pavements and also extend the service life of road pavements.
Hasan Akhtar discussed the current road infrastructure situation in Pakistan and also identified major causes of road damage. He also highlighted geotextile solutions and elaborated its key functions in order to encourage the textile sector to enter the market of geotextile manufacturing.

Soil Erosion Control
Erosion control is defined as: “The use of a geotextile or a geotextile-related product to prevent soil or other particle movements at the surface of, for example, a slope”23.
The erosion process is part of the geological cycle, a natural phenomenon, wherein water and wind are particularly aggressive factors causing soil erosion. A geotextile is used as part of an erosion-control system to protect the soil (marine embankment
slopes, riverbanks, bed protection) from this influence. Depending on the water’s force (flow rate, wave action, tidal surges) and the characteristics of the soil, the effects can be devastating (e.g. landslides).
The main function of the geotextile in an erosion-control system is the retention of the base material without the generation of unacceptable excess pore-water pressure. The geotextile replaces a conventional well-graded filter between the soil to be retained
and gabions, rip-rap or concrete-slab revetments, which protect the filter geotextile. Its particular opening size retains the soil and so avoids erosion of the slope. Furthermore, the geotextile must satisfy strength requirements.
