Research Of Highway Clay Roadbed Settlement And Impacting Effect

The construction and development of high-grade highway makes earth-rolling skill renew continuously. New rolling skill changes the traditional rolling method and improves the rolling effect. This subject introduces the rolling theory and main rolling indexes of the clay roadbed settlement and effect factor of the roadbed rolling effect. On the base the paper puts forwards to anew skill--impact rolling skill. This paper introduces the structure and working theory of thesettlement of impact roller, and put up a new dynamics model with stress fluctuation theory and the soil dynamics principle, at the same time, built a multi-index evaluation system for soil road section in impacting potency assay, and the advantage apply to highway construction in China are brought outo Ideal rolling effect can improve the integrate stability and bearing pressure of the roadbed, decrease the construction and maintains cost of highway.
