Is that dust potential hazard for the jet engines ?

New taxi way at this airport. They just build it. First aircraft Airbus A319 taxiing. Looks like builders forgot to sweep the tarmac. Is that dust potential hazard for the jet engines ? Here is the video for reference https://www.youtube.com/watch?v=9IgFzLTsXHs&t=89s

I'd guess it's a function of the composition of the dust. It might abrade blade leading edges, or if it's a "right" (wrong) material could conceivably melt in the hot sections and adhere to components, block cooling paths, etc.

I think it's unlikely it would be a direct threat to either loss of thrust or engine loss itself, but you could be looking at an earlier removal as a consequence. I doubt a single pass would do much, given there are aircraft operating in "dusty" environments on a regular basis.

Its concrete dust. They did't do a proper sweep

Taxiways at low power are unlikely to be much of a problem unless you eat the dust from the guy in front of you. The good news is that most of this dust gets blown into the grass where it sticks

The larger problem is this kind of crap on the runways at the chevron marks. If most of the takeoff for the day power up well downstream of the chevrons and some really heavy guy powers up upstream where the dust has settled than that can suck up into the engine and raise all kinds of problems.

Of course most rolling power-ups help prevent this

There is some data where clogged turbine blade cooling holes can be traced to some specific airports where recent runway work had taken place

When opening new taxiways at airports it is impossible to get rid of all the usual residual concrete dust from new pavements. Sweepers that are generally used at airports (similar to road sweepers) will only pick up a percentage. I dont know of any meachine that will guarantee that every single particle is removed. The dust after a while will dissipate. It actually always looks worse because of the blast from the engines out the back. More of a danger is loose stones from degraded taxiways that can be ingested and cause damage to blades.
