This relentless pursuit of "100% compaction" is not an isolated case. On the Xingha section of the G30 Lianyungang-Horgos Expressway, the Bomag BW226D-5CL roller, with its "golden weight" of 26 tons, successfully compacted a 46-centimeter-thick water-stabilized layer in a single pass, breaking through the efficiency bottleneck of traditional layered compaction, saving 50% of the construction period and reducing costs by 30%. Meanwhile, on the Shantou-Meizhou Expressway reconstruction and expansion project, an unmanned paver fleet pushed compaction precision to new heights. Thanks to BeiDou high-precision positioning, the rolling trajectory control accuracy reached within 3 centimeters, achieving a 100% pass rate for road surface smoothness, with a maximum value of only 0.7 millimeters, far exceeding the standard requirements.
These road rollers are no longer cold, steel behemoths, but intelligent partners endowed with the ability to "sense" and "think." Their core secret lies in their equipped lane temperature detection and matrix temperature field scanning system, essentially giving the equipment "infrared eyes" that can capture real-time environmental weather and road surface temperature distribution. The system intelligently coordinates, automatically adjusting vibration frequency and travel speed based on the asphalt's "temperature," ensuring compaction is completed within the optimal temperature window, completely eliminating insufficient compaction or asphalt aging caused by temperature runaway.
As global infrastructure demand aligns with the wave of green transformation, Chinese road rollers are writing new chapters on construction sites worldwide, leveraging their dual advantages of "hard technological strength + flexible application scenarios." From production lines in Luoyang to highways in Bangladesh, from the highlands of Ethiopia to ports in Europe, these steel machines are not merely engineering tools, but also "Chinese solutions" connecting the development needs of different countries-using precisely adapted technology and efficient, reliable services to ensure 100% compaction of every road, and continuously enhancing the global trust in "Made in China" with every roll.
