A major civil engineering project has been taking place since last November while most of Scotland was asleep.
Unlike Nigeria, the authorities in Scotland did not have to shut down their busy Glasgow airport to resurface the runway using the latest asphalt technology.

According to the BBC, there’s been minimal disruption because they’ve been doing it piece by piece in the middle of the night. The airport must be ready to reopen at 06:00 every morning.
So at just after 23:00 a convoy drives onto the darkened runway.

First comes traffic management with 600 traffic cones to enforce a strict one-way system.
Then the specialist vehicles: planers, pavers, rollers, sweepers and a gaggle of repurposed fire engines whose high platforms now carry huge floodlights.

Night becomes day again. Almost 200 workers have to be able to see what they’re doing.
This is the only runway at one of Scotland’s busiest airports but within a few minutes it looks like a motorway construction project.

Glasgow handles almost 100,000 aircraft movements a year. With the trend in the airline industry towards higher capacity, heavier aircraft, that means the runway takes a pounding every day.

This project is making it fit for the next decade.
If it looks like a meticulously organised operation that is because it has been well over three years in the planning.
Since last November, night by night, 120m at a time, this small army has been lifting off the runway’s surface and laying a new, hi-tech one.

Other work has also been taking place overnight, including replacing more than 200 runway and taxiway lights.
Most of it has been done with minimal disruption, indeed without passengers noticing.
The occasional delayed flight has missed the night time deadline and been diverted to an alternative airport.
But the airport’s operations director Mark Johnston says the plan has been to do the work at a time when it would least affect traffic.

That’s why it has been taking place through the winter.
“We have to notify the airlines far in advance of doing the works,” he says.
“We effectively take the runway at eleven o’clock at night and hand it back at five in the morning.”
It has meant hundreds of variables have been taken into consideration.

One example: the air ambulance normally based here has to decamp to Prestwick when the diggers move in.
It’s taken place night by night, but not every night. Before the new surface can be laid, the key science is meteorology.

If it’s too cold or too wet, everything has to be postponed.
On the night BBC joined them, the forecast was good and the first asphalt was laid before midnight.
Kevin Berry, the airfields operation director of the principal contractor VolkerFitzpatrick, has been checking the weather forecast since lunchtime.

“We’re checking the weather at twelve o’clock, we’re checking the weather at four o’clock, half past six, half past nine,” he explains, “And then we go.
“And we don’t go until we’ve got the material batched and ready to come.”
It is no ordinary material. It’s called Marshall asphalt, the surface of choice for civil and military runways.

Mixed with the bitumen are stones that have been ground down almost to the size of grains of sand.
Anything larger would not make the grade. Pebbles and high speed aircraft do not mix.
Marshall asphalt was first created before WW2 but project manager Roy Thomson says the particular mix they are using at Glasgow has a 21st Century edge.

“We’ve tried to develop an asphalt that’s capable of modern day fatigues and runway loadings, looking forward to the future.
“Glasgow Airport will have a polymer modified asphalt which will be the first runway in Scotland to adopt that material.”

Polymers are long chain molecules of the kind found in plastics and our own DNA.
Their use here will result in a runway that will perform better at extreme temperatures. It will resist rutting, cracking and fatigue and will last longer.
The clock ticks relentlessly towards 05:00.



[Scotland Shows Nigeria Runway Can be Fixed without Shutting Airport | THISDAYLIVE] is good,have a look at it! https://www.thisdaylive.com/index.php/2017/03/15/scotland-shows-nigeria-runway-can-be-fixed-without-shutting-airport/

Nice one
Naija just backward

Hey Scotland. we in Nigeria knows these things too. just like we knew it was also an act of politics by Kaduna state governor, a former FCT minister who knew what to achieve with the airport closure. In Nigeria. there's corruption in every plan.

Thank God you said Scotland..

Country wey never get 24/7 power supply...
rubbissssssh...

Technology and advancement does not come by night vigil, ablution or tithe.

For as long as religion, mysticism and conspiracy theories are your explanation for every phenomenon you must live in backwardness perpetually.

Imagine primitive people trying to compare Scotland with Nigeria.

People that came to visit and dominate you via ocean-going vessels over 400 years ago. 400 + years later you are still using canoes as your most common form of water transport.

Abeg go pray away your backwardness maybe when you open your eyes your runway would be built via modern technology.

Nigeria know anything?

You and Scotland dey the same level?
so why compare?

Don't let this distract you from the facts that illegal drugs are dangerous to your health

when people like the renowned grass cutter babachair is in government, such can't work.Nah to loot jare
