In the face of complex and ever-changing construction scenarios, intelligence is the core of improving quality and efficiency. The BOMAG BW 203 AD-4 AM CC roller is equipped with a unique secret - stepless amplitude technology, which can intelligently adjust the amplitude size and direction based on real-time feedback of compaction degree. Its integrated Evib compaction measurement system is like an on-board "intelligent supervisor", allowing drivers to have a clear understanding of the compaction progress. In addition, BOMAG 's efficient milling machine BM 2000/58 CC and precise paving machine BF 800 C-2L were also unveiled on site, jointly outlining its powerful full chain equipment matrix in the field of road construction.
