How to fix a wooden box on asphalt without drilling both asphalt and the box? 3

[vaselinerubrub]

Hello. We have a plywood box with dimensions: 3.13 x 2 x 1.84m. We are not allowed to drill holes in asphalt, but we have to ensure that the box wouldn't get stolen at night or if unattended. What tools or equipment could be used to make the box unmovable and heavy enough. I am thinking about placing stone plates inside, but due to the low budget, I would like to get ideas about other possibilities.

Thank you in advance.

Can you use an asphalt 'binder' as an adhesive? or does the box have to be removable? Can you coat it with 'grease' to make it very messy to remove?

How determined is the thief? What's so special about the box itself? Why wouldn't a thief just bring a sawzall and saw it open and steal the remainder of the box and the contents?

Otherwise, it would certainly seem that dik's adhesives approach is the only obvious solution, although weighing down the box could possibly work, but stone is pretty light, all in all. If you wanted to weigh it down, you would choose something that has substantially higher density than stone, more like tungsten or plutonium. The latter has the added advantage that few thieves would risk their lives stealing a box full of plutonium.

Note that you would only need a 4-mm layer of tungsten on the bottom of box will add 500 kg of weight

Weighing it down would seem the easiest solution, and the volume that the ballast is allowed to take up vs. the cost of the materials to add weight would determine what you use to make it heavy enough that it can't be picked up. Rocks may be the cheapest, but also take up a substantial volume. Concrete is not much denser, but it can be poured in to a uniform depth, leaving a more regular shape for the remaining space. Steel plates would take up less space, but if cost is more of an issue than the lost space, then it may not be the preferred option. As IRstuff noted, tungsten would take up very little of the volume, but it's also very expensive ballast.

Is there anything of value inside? If not, then put a window in it, in addition to 'gluing' it down just so people can see the contents are valueless.

It's also ludicrously hard, so there might those that'll want to steal the tungsten instead ;-)

My guess is that this is simply a theoretical problem solving exercise, to make OP think. We may be short-circuiting the learning process...

There will be solar panels installed on top of the box and a go-kart with electric appliances inside. Just like BridgeSmith said, tungsten and steel plates would be an expensive choice. If stone plates take up a lot of space, then I will just increase the box dimensions.

maybe just the warning sign or one stating radiation hazard:

Rather than drill holes in the asphalt, you could drive in say 2 #5 rebar, about 24" deep. This method is sometimes used to secure concrete wheel stops.
True it would cause a little damage to the asphalt, but fairly easily repaired. A strong adhesive may also cause asphalt damage when box is removed.
