Pepe's Towing in Los Angeles reports asphalt collapses where loaded semitrailers are parked with the landing gear down. On hot days the concentrated load of the landing gear sometimes punches through the asphalt.[1]

This is why truck dock areas are usually paved with concrete.

Years ago Chicago started putting concrete pads on the road at bus stops because the busses stopping in the exact same spot repeatedly was carving ruts into the asphalt.
A city I used to live in did the same thing when they refurbished all the major bus stops. I always wondered why
Also if a vehicle is stopped and the driver turns the wheel (with power steering this isn't hard) - it will eventually drill holes in asphalt - you can sometimes see this in house driveways where someone turns around.
You can even see the asphalt "waves" pushed by the buses stopping here over and over again
Yeah, my city is currently going through every bus stop in the city, redoing the pavement in concrete. Construction season has been nasty for us this year :p
I've lived in Washington DC for 20 years and I never realized why the bus stops here are concrete! Thank you for this.
Motorcycle riders also report their sidestands sinking into asphalt on very hot days, to the extent that many of them carry some kind of wide weight-spreading thing to put under the stand. Apparently a face plate (?) for an electrical junction box works great.
Usually, a crushed soda can is good enough to prevent the kickstand to sync in the pavement. You can usually find a can in a random parking lot. That, or find a strip of concrete. That's why sometimes motorcycle park on the sidewalk in front of big box stores on a hot day.
Yep, I use a soda can and have never had any issues.
My bicycle did this as kid in the summer
