Road construction machines for an electric road construction site

A service vehicle arranged to supply road construction material to a road construction work site comprising:

• a road construction machine,
• wherein the service vehicle comprises an electrical storage system (ESS) and an electrical connector arranged to interface with an electric system of the road construction machine in a mated configuration,
• wherein the ESS is arranged to at least partly power the road construction machine when in the mated configuration, and
• wherein the service vehicle and the road construction machine each comprise a mechanical coupling device configured to form a mechanical connection when in the mated configuration, wherein the mechanical connection transfers motive force between the road construction machine and the service vehicle in the mated configuration.

A road construction machine arranged for road construction at a road construction site comprising:

• an electric system for powering the road construction machine,
• wherein the road construction machine is arranged to interface with an electrical connector of a service vehicle in a mated configuration,
• wherein the road construction machine is arranged to be at least partly powered by a service vehicle electric storage system (ESS) when in the mated configuration, and
• wherein the service vehicle and the road construction machine each comprise a mechanical coupling device configured to form a mechanical connection when in the mated configuration, and
• wherein the mechanical connection transfers motive force between the road construction machine and the service vehicle in the mated configuration.

A method for constructing a road at a road construction work site comprising:

• configuring an electric road construction machine and one or more service vehicles to supply road construction material to the electric road construction machine at the road construction work site,
• wherein each service vehicle of the one or more service vehicles comprises an electrical storage system (ESS) and an electrical connector arranged to interface with an electric system of the road construction machine,
• docking the road construction machine with at least one service vehicle of the one or more service vehicles in a mated configuration at the road construction work site to transfer road construction material and electrical energy from the service vehicle to the road construction machine,
• at least partly powering the road construction machine by the ESS of the at least one service vehicle when in the mated configuration, and
• wherein the road construction machine and the at least one service vehicle each comprise a mechanical coupling device configured to form a mechanical connection when in the mated configuration, wherein the mechanical connection transfers motive force between the road construction machine and the at least one service vehicle in the mated configuration.
