This was one of the argued motivation for introducing the Platon system in Russia in addition to the fuel tax. It's an electronic toll system mandatory for trucks over 12 tons and costs every such truck ~5 USD cents per traveled km. Unfortunately it does not take into account current mass of a truck (probably because it's much harder to control and easier to cheat). Part of the proceedings goes to a federal fund for road maintenance, another one to the company (partially owned by an oligarch close to Putin) which has developed the system and currently maintenance it. This concession will work until 2027.
