W artykule przedstawiono zastosowanie teoretycznego modelu nawierzchni jezdni drogowej do komputerowych symulacji numerycznych badania płytą VSS na podstawie danych otrzymanych z badań ugięciomierzem dynamicznym typu FWD. Zawężając rozważania do analizy wartości wtórnego modułu odkształcenia (Ev2) do półprzestrzeni ograniczonej od góry warstwą z kruszywa łamanego stabilizowanego mechanicznie wykazano, że poprzez odpowiednie wykorzystanie wyników nieniszczących testów dynamicznych, symulacji testów statycznych oraz teoretyczno-numerycznych modeli nawierzchni jako składników matematycznej procedury odwrotnej, można otrzymać wiarygodne wartości tego parametru. Prezentowany eksperyment pozwala założyć, że proponowane tu procedury identyfikacji, pozwalają obliczyć wartość Ev2 z dokładnością zdeterminowaną pomiarem VSS na odcinku jednorodnym.
The paper presents the application of a theoretical model of road pavement, to computer numerical simulation studies of VSS test method, based on data obtained from dynamic deflectometer (FWD). Narrowing the discussion, to analyze only the secondary deformation modulus (Ev2), that was performed on the mechanically stabilized aggregate top layer of half-space, it was shown, that through the appropriate use of the results of dynamic non-destructive tests, simulation of static tests, theoretical and numerical models of pavements, as components of the mathematical inverse analysis, one can obtain reliable values for this parameter. The analysis of experiment results lets to assume, that the proposed here identification procedure, makes possible to calculate the value of EV2 (based on FWD data) with an accuracy determined by the VSS measurement on homogeneous section.
