Bolsters Operational Efficiency, Increases The Pavement Life


CSMIA adopted the widely acclaimed “Mill & Fill” technique for Runway 14/32 which are carefully orchestrated steps

MUMBAI, June 12 (The CONNECT) – Chhatrapati Shivaji Maharaj International Airport (CSMIA), completed the task major re-carpeting project for its secondary runway – Runway 14/32. With meticulous planning, execution, and commitment to strict timelines and safe operations, the Mumbai airport, managed by Adani Airport Holdings Limited (AAHL), has successfully achieved this crucial infrastructure enhancement on time.

CSMIA operates one of the busiest single-crossover runways in the world with an average of 950 flights. Thus, making it imperative that the runways are kept in optimal conditions to maintain continuous and safe aircraft operations during landing and take-off. The recarpeting initiative, which commenced on December 9, 2022, has concluded as planned, with completion achieved on June 10, 2023.

To ensure the project’s efficiency and swift progress, the runway remained closed for approximately 12 hours daily.

The major resurfacing work covered a substantial area, with the runway spanning an impressive length of 2210 meters (excluding the intersection portion) and boasting a breadth of 75 meters which led to the upgradation of all stressed portions of the runway surface by laying about 72,500 metric ton (MT) asphalt. CSMIA adopted the widely acclaimed “Mill & Fill” technique for Runway 14/32 which are carefully orchestrated steps. That includes precise removal of existing Airfield Ground Lighting fittings by core cutting, subsequent core filling with quick set concrete, precise milling of the existing surface to the required depth, precisely overlaying with layers of Asphalt (DBM, AC) using advanced paver machines, followed by coring on the new surface to fix the fittings as per the planned strip chart. Finally, comprehensive testing and commissioning were conducted after the meticulous installation of all necessary fittings.

Throughout the project’s duration, CSMIA implemented comprehensive measures to ensure flight operations remained uninterrupted.
