Technology for RCC(Roller Compacted Concrete)is important progress of concrete construction technology and Chaotic Vibratory Roller is modern technology of vibratory roller. Basing on the wide band vibration of chaotic vibratory roller produced in Shanghai and Xuzhou, the compaction mechanism of chaotic vibration is analyzed and new technology of CVRCC i.e. Chaotic Vibratory Roller Compacted Concrete is advocated.
