Method for evaluating of a quality of a generated pavement or a generated surface, generated by use of a construction machine, especially a road construction machine, road finishing machine or milling machine, having the following steps: receiving sensor values from one or more sensors and/or a sensor system of the construction machine; determining a specific sensor value combination within the sensor values, the specific sensor value combination being assigned to a specific quality situation; and outputting an operator message dependent on the specific quality situation.

In one aspect, a method of determining lateral edges of an asphalt mat deposited by a paving machine includes obtaining thermal image data of the asphalt mat at a thermal measuring device associated with the paving machine, and determining, on the paving machine, the lateral edges of the asphalt mat based on a threshold temperature value and the thermal image data. Other aspects include a method of generating a thermal map of an asphalt mat formed by paving machine, and a system for determining lateral edges of an asphalt mat deposited by a paving machine.

The robotic maintenance vehicle (RMV) has a propulsion system, a control system, an electrical power source, a maintenance module, a multi-axis robot, an optical system, and a location translator. The maintenance module is configured to hold different kinds of road maintenance materials. The multi-axis robot is configured to convey the road maintenance material from either the maintenance module to the road, the road to the maintenance module, or both. The optical system and the location translator are configured to be controlled by the control system and operate in conjunction to instruct the multi-axis robot where to pick up and/or place the road maintenance material. The multi-axis robot is configured to be selectively coupled to a distal arm tool.

A wireless asphalt measuring system is disclosed herein. The system takes thermal data of the asphalt via a thermal camera and distance data from a distance measuring instrument. A processing unit then calculates a metric, such as yield, based on the thermal data and distance data. The distance measuring instrument may communicate wirelessly to the processing unit and the processing unit may communicate to a local device or via the internet, eliminating the possibility of wires being damaged and rendering the system inoperable.
