The Ministry is primarily responsible for development and maintenance of National Highways (NHs).

State / Union Territory (UT) - wise details of reported damages that occurred on NHs during the last three years, including damages due to severe floods and water-logging, are at Annexure-I. 

Development and maintenance of NHs is a continuous process. The conditions of NHs are assessed from time to time by the Ministry and its various executing agencies such as National Highways Authority of India (NHAI), National Highways & Infrastructure Development Corporation Limited (NHIDCL), Border Roads Organisation (BRO), Public Works Departments (PWDs) / Road Construction Departments (RCDs) / Corporations of State Governments / Union Territories (UTs). The works on NHs are accordingly taken up from time to time as per traffic density, condition of road, inter-se priority and availability of funds to keep the NHs in traffic worthy condition; such works also include rectification of deficiencies and damages caused due to various reasons, rehabilitation and strengthening of NHs, providing adequate drainage systems, etc.

Various types of Maintenance and Repair (M&R) works taken up on NHs include Ordinary Repairs (OR), Periodical Renewals (PR), Special Repairs (SR) and Flood Damage Repairs (FDR).

The M&R of stretches of NHs, where either Development works have commenced or Operation, Maintenance and Transfer (OMT) Concessions/ Operation and Maintenance (O&M) Contracts have been awarded, are the responsibility of the concerned Concessionaires/ Contractors till the Defect Liability Period (DLP)/ the Concession Period.

M&R of balance stretches of NHs, including Restoration of damages due to severe floods and water-logging, are carried out regularly as per available budgetary outlay, inter-se priority and traffic density to keep such NHs in traffic worthy condition.

Further, the Ministry has decided that, from 2023-24 onwards, all maintenance works on NHs are to be carried out primarily through Performance based Maintenance Contract (PBMC) / Short Term (1- year) Maintenance Contract only. Consequently, all NHs stretches are to be invariably covered under ongoing works of development or maintenance or Defect Liability Period (DLP), with the responsibility of maintenance of such NHs stretches lying with the concerned Contractor /Concessionaire.

State / UT - wise details of funds allocated and expenditure incurred / funds released for M&R of NHs during the last three years are at Annexure-IIA. Apart from this, year - wise details of funds allocated and expenditure incurred / funds released to other Agencies for M&R during the last three years are at Annexure-IIB.

Some of the important Technological Interventions used in construction of NHs to make NHs less prone to damages are as follows: -

1. Road level is fixed based on hydrological modelling, well above the Highest Flood level.
2. Geo-synthetics are used for fill & cut slope stabilization and erosion protection measures to minimize landslides.
3. Modern Rock fall protection measures such as wire rope and gabions as river training works are used.
4. Latest compaction equipment are being used to compact the earth to the maximum and making it less prone to damages against heavy rain and floods.
5. Soil stabilisation is being widely used to improve the properties of soils.
6. Stabilisation Technology for soil and aggregate which induces more resistance to water induced distresses.
7. Nanotechnology anti stripping agent for bituminous mixes are used.
8. Cement Grouted Bituminous Macadam for bituminous wearing courses for high rainfall region.
9. Concrete/ White Topping for water resistance pavement.
10. Micro surfacing to have waterproofing bituminous surface.
11. Porous permeable pavement.
12. Nanotechnology based liquid water proof membrane.

• (xiii) Cold patch mix for maintenance.

14. Geo-membrane/ geo-composite for drainage purpose.   
15. Chute drain and median line drain with geo cell.

 

ANNEXURE-I

State / UT - wise details of reported damages that occurred on NHs during the last three years, including damages due to severe floods and water-logging: -

 

 

ANNEXURE-IIA

State / UT - wise details of funds allocated and expenditure incurred / funds released for M&R of NHs during the last three years: -

Alloc. – Allocation; Expd. - Expenditure

Expenditure in some States is in excess against their allocation, however total expenditure in the country is well within the Ministry's overall Budgetary allocation.

$- Erstwhile Jammu and Kashmir State before reorganisation to State of Jammu & Kashmir and UT of Ladakh

^- Erstwhile UTs before merger

*- Negative allocation is reflected as funds were re-appropriated from State PWD to NHAI/NHIDCL due to lower expenditure being incurred. However, the State/UT wise allocation was not reduced due to sanction purposes.

**- Expenditure included in State/UT wise

Allocation and expenditure in the above statement includes PR/IRQP which is funded from NH(O) from 2021-22 onwards. Therefore, total allocation is greater than total outlay of M&R.

ANNEXURE-IIB

Year - wise details of funds allocated and expenditure incurred / funds released to other Agencies for M&R of NHs during the last three years: -

Alloc. – Allocation; Expd. - Expenditure

This information was given by the Union Minister of Road Transport and Highways, Shri Nitin Gadkari in a written reply to the Lok Sabha today.
