The vibration test, numerical simulation and compaction experiment of the chaotic vibratory rollers (three types： 0.75t, 101 and 14t) are completed for transform theoretical research of chaotic vibration mechanics into technology achievement in road roller engineering.

It is proved that the working efficiency of chaotic vibratory roller is 12.2% higher than that of traditional one. One type of heavy chaotic vibratory roller (14t) is used in highway development in west China.
