Modelling of control actions at the operational stage of the life cycle of roads
Introduction. One of the complex problems of road asset management is the lack of unified “integral” indicators of their condition, which simultaneously take into account the change in the longitudinal smoothness of the road surface, visual condition, and the general modulus of elasticity at the ope...
