Embodiment Construction

[0017] Referring to Figure 1, there is shown a laying system 10 according to the present invention. Laying system 10 may include one or more machines, such as multiple different machines, and in some embodiments even multiples of the same machine. Each of the machines of paving system 10 is configured to interact with, and typically perform a particular job on, the paving material. In an exemplary embodiment, the laying system 10 includes a laying machine 12 and three compaction machines 14 , 16 and 18 . One or more supply machines 40 (eg, haul trucks, material transport vehicles, etc.) may be provided to supply other machines of the laying system 10 with paving material for laying the work surface. While only certain machines are shown, it should be appreciated that for larger laying jobs, system 10 may include additional laying machines, additional compactors, feeding machines, etc. as well. Additionally, while in many embodiments system 10 may be used to pave a specific w...

Abstract

The present invention relates to a paving system and system. The method includes establishing a plan for paving a work area which is based on a positional temperature model. The method further includes receiving temperature data for paving material and comparing the temperature data with data predicted by the positional temperature model. Operation of the paving system is adjusted where actual data differs from model predicted data. A paving system and control system are provided having an electronic control unit configured to compare electronic temperature data with a positional temperature model for paving material. The electronic control unit can control machines of the paving system based on comparing actual data with model predicted data, and can further update either or both of a plan for paving a work area and the positional temperature model itself based on differences between actual data and model predicted data. A complete temperature profile of a paving work area, including a comparison with the model may be recorded in computer readable memory for forensic and predictive analysis.

Description

technical field [0001] The present invention relates generally to systems and methods for laying, and more particularly to evaluating temperature data of paving materials during laying for use in controlling and / or recording the operation and performance of the laying system. Background technique [0002] A typical system for paving a work area, such as a parking lot or road, may include a number of different machines. Feed machinery, such as haul trucks, may be used to convey the paving material that is distributed and compacted on the work surface. The laying machine can be supplied directly by haul trucks or material transport vehicles. The paving machine typically dispenses the paving material and initially compacts the "mat" of the paving material with a flat plate mounted at the rear end of the paving machine. In many systems, a compaction machine known in the art as a breakdown roller (breakdown roller) follows relatively closely behind the laying machine. In some ...
