Installation of pilot road construction with shallow drains completed. Parameters of the installation make it possible to arrange a structure that corresponds to real conditions, that is, the parameters of a road of category III and study the processes of formation of the filtration flow in the drainage trench which is impossible with real objects. The laboratory installation was used to study operating conditions of drainage structures: a layer of crushed stone of 20–40 mm fraction and two types of transverse shallow drains with different filler materials in the trench. In the process of a series of experimental studies, the volume of water drained from the trench and drainage time was measured. Temperature and humidity conditions of road construction have been analyzed. The influence of oscillating processes on moisture production and water discharge intensity in shallow transverse drains has been investigated. According to the study results, based on the methods of mathematical statistics, unified equations of the correlation-regression model concerning the mode of operation of the drainage structure were constructed depending on initial soil moisture in the roadbed. The methodology for choosing the optimal structures of shallow drainage has been substantiated and developed.
