原始语种摘要: ABSTRACT(#br)In northern regions, the frost heave of the subgrade soils due to formation of ice lens is the main mechanism involved in the high degradation rate of the flexible pavement. This paper presents developments of flexible pavement damage models, developed through a multiple linear regression analysis, associated long-term roughness performance to frost heave and degradation mechanisms. Actually, there is no deterioration model that establishes a link between frost heave and flexible pavement. At a design stage, those models would be essential to evaluate the benefits or consequences to have a frost heave lower, equal or higher than the allowable threshold values established by the MTMDET according to the roads functional classification. The result presented illustrate that a...
