Back road seriously fails concrete truck driver

A back road seriously fails a concrete truck driver in this video filmed on some remote roadway. 

In the clip, the concrete truck driver is standing back, away from his truck with his camera out, as the truck drops concrete on the shoulder of the back road, seemingly to reinforce it. 

Just as the driver is trying to fix the road, it gives way under the truck, sending the rig sliding down the side of what seems to be a mountain until it is literally out of sight. 

The most impressive part of the ordeal in our eyes is that the concrete truck driver said absolutely nothing as he filmed his truck sliding off and rolling away.
