State-wise  &  year-wise  details  of  road  length  constructed under various verticals of PMGSY can be accessed at https://omms.nic.in -> Progress Monitoring ->  Monthly  Progress Report -> Financial Year-wise Achievement. Similarly, State-wise & year-wise  details  of  road  length  constructed  using  new/  green

technologies under PMGSY can be accessed at https://omms.nic.in>Proposals->Technology Abstract.

The use of new and green technologies in road construction economises the construction cost of rural roads, while also enabling the  effective  disposal  of  various  industrial  and  municipal  wastes. This not only saves the environment but also conserves the use of virgin  mining  materials  effectively.  Further,  it  also  enhances  the execution capacity and reduces the construction period.

- (c): The  Government  accords  highest  priority  to  ensuring  the quality and durability of rural roads constructed under the PMGSY. The following measures have been taken to ensure the quality and durability  of rural roads constructed under PMGSY:
- (i)  A comprehensive framework has been put in place to ensure that all roads are built to prescribed technical standards and maintained effectively  over  time.  PMGSY  roads  are  constructed  based  on detailed  specifications  and  guidelines  issued  by  the  Indian  Roads Congress (IRC) and the Ministry of Rural Development. Designs are vetted  at  both  the  State  and  Central  levels  to  ensure  structural integrity and suitability for local terrain and climate.
- (ii) Further, a three-tier Quality Monitoring System is in place.  At the first  tier,  quality  checks are made by the executing agency at the field  level.   At  the  second  tier,  independent State Quality Monitors (SQMs) inspect all the work at every level. At the third Tier, National Quality  Monitors  (NQMs)  deputed  by  the  Ministry  conduct  surprise inspections  across  States  to  ensure  objectivity  and  compliance. PMGSY  uses  the  Online  Management,  Monitoring  and  Accounting System (OMMAS) to track physical and financial progress, including quality inspections. Graded inspection reports from SQMs and NQMs are recorded and monitored in real-time.
- (iii) All  contractors are legally bound to maintain the roads for five years post-construction under a Defect Liability Period (DLP) clause. Payments are linked to satisfactory maintenance, ensuring accountability and durability.
- (iv)  The  Ministry  has  promoted  the  use  of  innovative  and  climateresilient  technologies  (e.g.,  waste  plastic,  cold  mix,  Full  Depth Reclamation,  etc.)  to  enhance  the  lifespan  of  roads  and  reduce

environmental impact. More than 1.24 lakh km of roads have been constructed using such technologies as of July 2025.

- (v) Continuous training of engineers, contractors, and quality monitors  is  undertaken  through  reputed  institutions to  strengthen technical competencies in road design, construction, and maintenance.

These  measures,  taken  in  a  coordinated  and  systematic manner,  have  significantly  contributed  to  improving  the  quality, durability, and  sustainability of rural  roads  constructed  under PMGSY.

- (d): The Ministry of Rural Development has taken several proactive measures to promote the adoption of new-age, sustainable construction materials and technologies under the PMGSY, with the twin objectives of improving road quality and promoting environmental sustainability. Key steps taken in this regard include the following:
- (i) In 2013, the Ministry issued guidelines mandating that a minimum of 15% of the total annual road length in each State be constructed using new and green technologies, including waste plastic, fly ash, cold mix, etc.
- (ii) A comprehensive Vision Document was released in 2022 to guide States  in  mainstreaming  innovative  materials  and  techniques. The document promotes the use of many proven technologies, tailored to  suit  varied  geographic  and  climatic  conditions.   Some  of  the approved technologies in use are:

Cold  Mix  Technology:  Enables  bituminous  road  construction without heating, ensuring energy savings and suitability in remote or hilly areas.

Waste  Plastic:  Used  in  bituminous  roads  in  surface  coats  to improve durability and resistance to water-induced damage.

Cement stabilisation: It is a soil improvement technique used in road construction to enhance the strength and durability of weak or poor-quality soils by mixing them with cement.

Full Depth Reclamation (FDR): It is a rehabilitation method that involves  recycling  of  an  existing  distressed  bituminous  surfacing

course and its underlying layers into a new, stronger base layer. By this process use of carted stone aggregates can be avoided or very minimal use of carted aggregates used.

Panelled  Cement  Concrete: It  refers  to  a  method  of  laying cement  concrete  pavements  in  defined  rectangular  or  square panels)  to  control  cracking  due  to  shrinkage, sections  (called temperature changes, or structural loading.

Cell-filled  concrete:  The  compacted  sub-grade  /  sub-base  is covered with form work of plastic cells, which ultimately gets filled &

with concrete to act as pavement. Highly serviceable maintenance-free pavement is obtained with extremely low cost.

Use  of  Steel/  Copper  Slag: Steel  and  copper  slag  can  be effectively  used  in  the  construction  of  rural  roads,  offering  both economic  and  environmental  benefits.   It  can  be  a  sustainable alternative to natural aggregates in road construction.

Use of Jute/ Coir: The use of natural geotextiles like jute and coir in road construction is a sustainable and cost-effective solution for improving soil strength and stability, especially in rural and lowvolume roads

Fly Ash: Utilised in sub-grade and embankment construction to enhance strength and reduce environmental impact.

Roads constructed using green technologies are closely monitored  for  performance. Best  practices  and  case  studies  are shared across States to encourage wider adoption. As of 31st July 2025, more than 1,24,688 km of road length has been constructed using  new  and  green  technologies  under  PMGSY,  contributing  to cost savings, longer pavement life, and reduced carbon footprint.

(e): Real-time  data  of  inspections,  quality  ratings,  and  grievance redressal is available in the Citizen section of the PMGSY website hosted  at  https://omms.nic.in  under  the  Quality  Grading  Abstract and MeriSadak Citizen Feedback System.
