STATEMENT REFERRED TO IN REPLY TO PARTS (a) TO (e) OF LOK SABHA STARRED QUESTION NO. 271 FOR ANSWER ON 04.08.2022 ASKED  BY  SHRI  SUDHEER  GUPTA  AND  SHRI  RAVI  KISHAN REGARDING DAMAGE TO NHS DUE TO HEAVY RAINS

(a) to (c) State  /  Union  Territory  (UT)-wise  details  of  reported damages that  occurred  on  National  Highways  (NHs)  due  to  heavy rains, landslides, floods, etc. so far during 2022-23 are annexed.

The damages caused to some sections of NHs due to heavy rains, landslides, floods resulted into temporary disruptions of traffic movements; however, the Ministry ensured that immediate restoration works of such damaged NHs stretches, including those connecting pilgrimage centres and providing inter-state connectivity, were promptly carried out and the stretches were made traffic worthy within the earliest possible time; this is a continuous process.

- (d) The Ministry has no proposal to set up a separate fund to carry out  reconstruction  and  repair  of  NHs  damaged  due  to  floods. Budgetary allocations are being made every year to keep NHs traffic worthy.
- (e) Some  of  the  important  Technological  Interventions  used  in construction of NHs to make less prone to damages are as follows: -
- (i) Road  level  is  being  fixed  based  on  hydrological  modelling, well above the Highest Flood level.
- (ii) Geo-synthetics are being used for fill & cut slope stabilization and erosion protection measures to minimize landslides.
- (iii) Modern Rock fall protection measures such as wire rope and gabions as river training works are used.
- (iv) 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.
- (v) Soil stabilisation is being widely used  to improve  the properties of soils.
- (vi) Stabilisation Technology for soil and aggregate which induces more resistance to water induced distresses.
- (vii) Nanotechnology anti stripping agent for bituminous mixes are used.
- (viii) Cement Grouted Bituminous Macadam for bituminous wearing courses for high rainfall region.
- (ix) Concrete/ White Topping for water resistance pavement.
- (x) Micro surfacing to have waterproofing bituminous surface.
- (xi) Porous permeable pavement.
- (xii) Nanotechnology based liquid water proof membrane.
- (xiii) Cold patch mix for maintenance.
- (xiv) Geo-membrane/ geo-composite for drainage purpose.
- (xv) Chute drain and median line drain with geo cell.
