Summary

Introduction. A critical consequence of insufficient drainage and overwetting of the road structure is a reduction in its strength and bearing capacity due to decrease of the elasticity modulus of the subgrade soils and the pavement base layers. Attempts of sealing the road pavement are not always effective; the deterioration of its riding qualities during operation cannot reduce the intensity of water penetration into the road structure. It requires the arrangement of shallow drainage systems, especially on the overwetted road sections.

Issue statement. Shallow drainage systems are arranged in the working area of the subgrade, they are underground structures which makes it impossible to monitor their performance. Analysis of the research provided in the paper causes the need to identify the efficiency of shallow drainage systems performance, both by the intensity of drainage and under the impact of vibration from vehicles. The only way to solve this urgent issue is to conduct experimental research on large-scale models that maximally meet the field conditions.

Objective. The objective of this work is to study the performance of transverse shallow drainage  systems (TShD) by the intensity of drainage taking into account the impact of vibration using the laboratory facility of the road structure.

Materials and methods. In the educational and scientific laboratory of the Department of Transport Construction and Property Management of the National Transport University, a series of studies of two types of shallow drainage systems with tubular drain covered with coarse sand and crushed stone core was carried out on an experimental facility of the road structure. The installation parameters correspond to the III and IV categories of the highway. In accordance with the field measurements of vibration indicators, the facility simulating the vibration from the vehicles was designed and built. The experiments were performed both with and without vibration impact from vehicles. The road structure facility is equipped with a rainfall simulation system which operated in the mode of rainfall intensity of 5 % precipitations.

Results. During the research, the modes of water flow formation were determined and the intensity of draining by a drainage trench with a tubular drain and by a drainage trench with a crushed stone core was measured. According to the results of measurements, the impact of vibration from the vehicles on two types of drainage systems was analyzed and correlation-regression dependencies to determine their drainage intensity depending on the initial humidity of the subgrade were obtained.

Conclusions. According to the results of experimental studies, the shallow drainage system with crushed stone core drains more water by an average of 10 % without vibration impact, and by 14 % more under the vibration impact, in time, respectively, in 7 and 11 times faster than the system with tubular drain. This confirms its higher efficiency. When comparing the respective types of drainage systems with each other without vibration and with it, it can be concluded that the intensity of drainage of the system with a tubular drain is almost not affected by vibration.
