Description

technical field [0001] The invention relates to the technical field of road construction intelligent construction, and in particular relates to a BIM-based road compaction synchronous monitoring and feedback control system. Background technique [0002] One of the most important links in the compaction process in road construction. Engineering practice and experimental research at home and abroad have already proved that construction machinery must be used for careful compaction during the construction of the subgrade pavement structure layer, so as to improve the structure of the subgrade and pavement. The overall strength of the layer and the pavement increases its stability, so as to reduce or even avoid various early damage phenomena that may occur on the pavement, thereby greatly improving the performance and service life of the pavement. In order to ensure that the road compaction quality meets the specified requirements, it is an important means to monitor the compact...
