Good thing roads never wear down, otherwise radioactive material would leach from the cracks into the water supply.

But roads never crack so it's fine. Once the road is poured it's a permanent fixture.

I don't understand... What's the purpose of using this material? Is it just a cheap material available for making asphalt? Does it have some special property besides radioactivity???

A PILOT FOR WHAT

"Irradiate the Roads? You don't actually believe this do you?"

"Eh, gotta irradiate something!"
