The road surface efficient cleaning vehicle adopts the latest research results of fluid mechanics. By using the principle of negative pressure pure suction and combined with the patented roll sweeping technology, it realizes the deep cleaning operation of the water stable layer after milling and before spreading oil, and effectively removes the surface gravel, dust and adhesive garbage, which fully meets the construction requirements. Recently, we have had a successful road show in Zhejiang Province and conducted technical exchanges with industry experts.
