| Abstract: | Based on the deflection equivalence principle,the article uses the elastic multilayer theory and finite element method to stimulate load mode of rigid loading board.Also,the road importance and construction variability index are introduced with the requirement of modulus of resilience.The methods of determining the treatment depth of roadbed inorganic binding material is given in order to provide the suggestive treatment depth value for different road grade. |

| Keywords: | Roadbed Deflection equivalence Modulus of resilience Treatment depth |
