COMPLEX FOR EXPERIMENTAL RESEARCH OF DYNAMIC LOAD FROM ROAD CONSTRUCTION EQUIPMENT ON SHALLOW-LAYING DRAINAGE STRUCTURES AT THE STAGE OF THEIR INSTALLATION

Oleksandr Razboinikov Volodymyr Poliakov

Ensuring a favorable water-thermal regime and removing excess moisture from the base layers of the road surface becomes an important task when designing stable and durable road structures. In the context of building a road structure, shallow-laid drainages act as a necessary element to increase its bearing capacity. However, there are cases when at the stage of arrangement under dynamic loads from wheeled vehicles and road construction equipment in particular, shallow-laid structures collapse. This is explained by the fact that the soil density during construction and repair work has not yet reached its regulated values. Construction equipment moving over drainage pipes creates additional dynamic loads, which leads to their destruction. The article proposes a constructive solution for determining the values of destructive dynamic loads from road construction equipment on shallow-laid drainage structures. The features of the design, calibration and arrangement of the measuring platform of the complex for experimental studies of dynamic loads from road construction equipment on shallow drainage structures are presented, as well as the features of preserving the obtained results of experimental studies
