Project Overview
Indira Gandhi International Airport (IGI), New Delhi, required evaluation of Pavement Classification Number (PCN) for approximately 3.5 lakh sq.m of runways, taxiways, and apron surfaces to support safe aircraft load management and long-term pavement planning.
Translink Infrastructure Consultants Pvt. Ltd. was appointed to conduct HWD testing, structural analysis, and PCN computation in accordance with ICAO/FAA guidelines.

Challenges
The field testing had to be carried out during restricted operational windows, requiring precise coordination, and efficient use of limited access time. Additionally, PCN was evaluated using both COMFAA and ELMOD, and where the results differed, careful engineering judgement was needed to interpret the variation based on pavement condition, layer properties, and expected aircraft loads.
Solutions
Translink deployed a specialized airside testing team with well-structured workflows to complete HWD testing efficiently within the allotted access periods while maintaining all airside safety protocols.
In parallel, analysis teams processed the data using both COMFAA and ELMOD methods, reconciling structural response, layer properties, and operational requirements to finalize PCN values.
Impact
The assignment enabled reliable PCN classification for key operational pavement sections, supporting safe aircraft movement planning and evidence-based maintenance scheduling.
