The obtained formulas and calculation algorithm are the theoretical basis for calculating the homogeneity and reliability of two-layer and multilayer structures according to the limit state criteria at the design stage, taking into account the achieved level of quality of mixtures and the arrangement of base and pavement layers using bitumen and asphalt modifiers by road organizations. They were used to perform multivariate calculations of pavement structures. Product Description popup.authors Gameliak Igor P.
