Cable protection - how to attach to asphalt?

[Taxture]

As previously mentioned, use concrete screws
Asphalt is usually 2-3 layers each 5cm thick
So screws that are 100mm or longer

Do you really think concrete screws hold in asphalt?

Isn't it better to use French wood screws that are screwed into a plug that expands in the asphalt?

Thanks for the tips!

I will try with plugs and see how well it holds! 300kg on concrete it says. hmmm

Thanks for the help!!

The asphalt is soft, so using an expanding plug, I would say, is worse than using a screw that cuts into the asphalt.

Exists asphalt screw
Surely concrete screw with another name

Maybe a bolt that expands at the bottom? Then it would be like an anchor?

Molly maybe?

I believe most options should work, in the worst case you might need to insert new screws after a few months.

It will be a nice speed bump during construction, if nothing else.

Have you checked that the cable's diameter fits in the protection, if I remember correctly you were going to have a large subscription?

I have attached speed bumps with lightweight concrete screws, works perfectly. Available at least 140 mm long at the nearest hardware store.

Had loose rubber speed bumps where I lived before, they were attached with long ribbed spikes that were hammered into the asphalt. The spike was hammered in at an outward angle. Never came loose; in the fall, they were pulled up with a crowbar. The holes disappeared on their own; we never found the old holes when they were supposed to go back in the spring. A thicker screw can be driven directly into the asphalt.

There are asphalt screws
Probably concrete screws with another name

Our road association received such screws when we bought rubber speed bumps.
Didn't work at all, concrete screws didn't work either.
But it probably matters a lot how thick the asphalt is, with us it seems to be only 1 layer 4-5cm.
Have not engaged in any screw solution yet, so the bump is lying loose.

There are bumps with studs underneath. We have about 10 cm and those screws pulled well.
