What you need to know about PMGSY new technology guidelines for use of coir geotextiles in road construction?

According to the PMGSY new technology guidelines for road construction, 15% length in each batch of proposals, is to be constructed using new technologies.

  • Out of this 5% roads are to be constructed using IRC accredited technology.
  • The IRC has now accredited coir Geo textiles for construction of rural roads.
  • As per these instructions, 5% length of the rural roads under PMGSY-III will be constructed using Coir Geo textiles.
  • Accordingly road will be constructed using coir geo textiles in following 7 states of the country namely,
    1. 164 km in Andhra Pradesh
    2. 151 km in Gujarat
    3. 71 km in Kerala
    4. 328 km in Maharashtra
    5. 470 km in Odisha
    6. 369 km in Tamil Nadu
    7. 121 km in Telengana.
  • Thus, 1674 km road will be constructed using Coir Geo textiles for which there will be a requirement of 1 Crore Sq. meter of coir Geo-textiles, estimated cost of which would come to Rs.70 Crore.

What you need to know about Pradhan Mantri Gram Sadak Yojana?

The Pradhan Mantri Gram Sadak Yojana (PMGSY) is a nationwide plan in India to provide good all-weather road connectivity to unconnected villages. This Centrally Sponsored Scheme was introduced in 2000 by the then-prime minister of India Late Shri Atal Bihari Vajpayee.

The PMGSY is under the authority of the Ministry of Rural Development and was begun on 25 December 2000. It is fully funded by the central government.

During November 2015, following the recommendations of the 14th Finance Commission, the Sub-Group of Chief Ministers on Rationalization of Centrally Sponsored Schemes, it was announced that the project will be funded by both the central government (60%) and states (40%).


The aim was to provide roads to all villages

  • With a population of 1000 persons and above by 2003.
  • With a population of 500 persons and above by 2007.
  • In hill states, tribal and desert area villages with a population of 500 persons and above by 2003.
  • In hill states, tribal and desert area villages with a population of 250 persons and above by 2007.

Of 178,000 (1.7 lakh) habitations with a population of above 500 in the plains and above 250 in the hilly areas planned to be connected by all-weather roads, 82% were already connected by December 2017 and work-in-progress on the remaining 47,000 habitations was on-track for completion by March 2019.

The average speed of road construction under the PMGSY was 98.5 kilometers per day from 2004 to 2014, it rose to 130 km per day in by 2016-17.

PRELIMS Background Bites

What is Coir?

Coir or coconut fibre, is a natural fibre extracted from the outer husk of coconut and used in products such as floor mats, doormats, brushes and mattresses. Coir is the fibrous material found between the hard, internal shell and the outer coat of a coconut.

It has the advantage of not sinking, so can be used in long lengths on deep water without the added weight dragging down boats and buoys.

Coconut fibre (coir) is also using as a construction material because Fibres which are eco friendly, pollution free and do not adverse impact on the environment and its constituents are called natural fibres. If these material fibres are used in construction materials, it could save the bio-reserves.

Properties of Coconut Fibre

  • Coconut fibre has superior physical and chemical properties.
  • It is resistant to thermal conductivity, high toughness, ductility, durability and is renewable and is cheap.
  • Also it is capable of taking strain, four times more, than other fibres.
  • Hence coconut fibre can be a better alternative as construction materials.
  • It was observed in experimental study that with partial replacement of 2% CF with cement, the compressive strength is increased.

What are Coir Geotextiles?

  • Basically, Geotextiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain. Coir Geotextiles are permeable fabric, natural, strong, highly durable, resistant to rots, moulds and moisture, free from any microbial attacks.
  • Coir (coconut fiber) geotextiles are popular for erosion control, slope stabilization and bioengineering, due to the fabric’s substantial mechanical strength.
  • Geotextiles and related products have many applications and currently support many civil engineering applications including roads, airfields, railroads, embankments, retaining structures, reservoirs, canals, dams, bank protection, coastal engineering and construction site silt fences or geotube.
  • Usually geotextiles are placed at the tension surface to strengthen the soil. Geotextiles can improve soil strength at a lower cost than conventional methods.
