Aircraft parking spaces at Changi Airport are being ripped up and replaced with recycled concrete mix as part of an ongoing drive to go green.
Thirty-one of the 80m by 80m spaces - officially termed stands - will be repaved over the next 10 years.
Concrete aggregates extracted from the spaces, which are nearing the end of their lifespan, are used to form a new mixture. This material - which is as good as new, will be used to replace the 31 stands at Terminal 1, Terminal 2 and the cargo area. There are a total of 146 aircraft parking stands at the airport.
Mr Teoh Eng San, assistant vice-president for engineering and development at Changi Airport Group, said the company “has to be prudent and rehabilitate our parking stands at appropriate times”.
He added that the pavement has an average lifespan of about 20 to 25 years, depending on factors such as usage, and wear and tear.
The stands at the airport have been in use for more than 30 years - longer than average - because of high-quality construction and rigorous maintenance work.
