Abstract: A method for operating a roadbuilding machine and a roadbuilding machine, in which the health risks to the operator during operation are reduced without the paving quality of the roadbuilding material being reduced in the process. This is achieved by way of an undercarriage and/or at least one further component or, respectively, working component of the roadbuilding machine being remotely controlled by an operator, who is located outside the roadbuilding machine, via a transmitting module. In order to operate a roadbuilding machine, an operator is tied to the roadbuilding machine and therefore exposed to harmful fumes. In addition, the flexibility of the operator is reduced as a result.

Abstract: A method by means of which the paving result of the road covering can be improved. For the production of a road covering, road-building material is supplied by a pivoting conveyor of a feeder to a supply container of a road paver. In the case of a relative movement between the feeder and the road paver, the pivoting conveyor has to be manually readjusted, which can result in irregularities in the road covering. This is achieved in that the container of the at least one construction vehicle is detected by at least one sensor unit of the road-building machine.

Abstract: A method for operating a self-propelled road construction machine as well as a road construction machine with which an adjustment of the traction of the wheeled undercarriage can be performed in a quick and easy manner by monitoring and actively regulating the traction of the tires in dependence on the operating mode of the road construction machine. Pavers and feeders for the making of road covers have a wheeled undercarriage, especially with pneumatic tires. For a uniform production process of the road cover, adequate traction of the tires is needed. For this, prior to the start of the production process the tire air pressure of the tires is decreased, and it is increased once again for travel on the road, and the manual adjustment of the tire air pressure to the installation conditions and/or to the operating mode of the road construction machine is time consuming and cost intensive.

Abstract: A road paver (10) and a loader and a homogenizing mechanism (17) which permit optimum quality of the road building material without the operation of the road paver (10) or of the loader being impaired. Road coverings are customarily produced from materials such as asphalt by means of road pavers (10). In order to ensure optimum durability of the road covering produced, the road building material is homogenized by mixing devices prior to being laid. The continuous mixing of the road building material requires a very large amount of energy and results in severe wear phenomena in the mixing devices.
