'Slippages reveal design flaw on Kanpur-Lucknow e-way'
Slippages on the Kanpur-Lucknow Expressway suggest design issues, not construction defects. Affected stretches will require rebuilding from the ground up, officials stated. A preliminary investigation identified weak, plastic soil as a primary cause. Poor drainage also contributed to the expressway's structural problems. The government awaits a final report on the detailed investigation.
Sections of the Kanpur-Lucknow Expressway's opening have shown signs of slippage, suggesting a design issue rather than a construction problem, according to a senior government official. The affected areas will need to be entirely rebuilt from the base up. The official emphasized the importance of stringent design standards in projects, particularly as this expressway was constructed under the Hybrid Annuity Model (HAM).
The central government is eagerly awaiting the final report from an expert who has been conducting a thorough investigation into the issue. The investigation did not reveal any flaws in the road's thickness or the underlying pavement layers. The problem, according to the expert, stems from the use of weak, highly plastic soil beneath parts of the expressway.
This type of soil becomes weaker when wet and can deform under pressure. The preliminary findings also point to inadequate drainage as a contributing factor. The hybrid model of project execution means that the private developer is responsible for the operation and maintenance of the expressway for the entire 15-year concession period.
