Unblocking chaos: Re-connecting Tripura to the rest of India

LOCATION

National Highway 44, Churaibari, near the Assam-Tripura border, India

Client

PWD (Buildings and NH), Government of Assam

Product used

StrataWeb®

Application

StrataWeb® used for rehabilitation of a damaged section of NH-44

About the project

The National Highway NH-44 is a major road artery for the North East. The stretch of this highway leading to the border of Assam and Tripura (two states in the northeast of India) is the only land link between Tripura and the rest of the country. NH-44 is the state’s lifeline for supplies and victuals and all commercial activities.

The subgrade of the highway is highly plastic, with weak clayey soil. Conventional repairs were attempted, which were unsuccessful in allowing smooth traffic across this 500 m stretch. There were two essential issues to be addressed: A) Drainage of the pavement section and its subgrade. B) Strengthening the pavement section. Strata recommended StrataWeb® within the pavement section to solve both these issues.

At first, the remnants of the existing road were scrapped off. The subgrade was then dressed, levelled and compacted. A non-woven geotextile was placed above the compacted surface to prevent intermingling of the engineered section with the weak plastic subgrade. The highway opened to all traffic immediately after the granular base was laid. The bituminous concrete and the dense bituminous macadam layers were placed later.

 

It has been candidly acknowledged by the Assam PWD, to quote: “The NH-44 at Churaibari once became infamous for mud and slush is now transforming into heaven of beauty. All this has been made possible by the use of Geocell in Road construction”.
