RESEARCH ON THE EFFICIENCY OF SMALL PACKAGE DRAINAGE FUNCTIONING IN ROAD CONSTRUCTIONS


ABSTRACT

Bubela A.V. Research of efficiency of functioning of drainage of small laying in road constructions. Visnyk National Transport University. Series «Technical sciences». Scientific and Technical Collection. - Kyiv: National Transport University, 2020. - Issue 1 (46).

The article proposes and analyzes the types of small drainage drainage for the effective removal of moisture accumulated in road structures.

Object of study - drainage systems for drainage of road construction.

Purpose of the work is to determine the effectiveness of the road structure under the influence of precipitation and infiltration moisture.

To avoid long-term wetting of the pavement layers and the foundation of the road structure, it is necessary to prevent the accumulation of a large amount of free water in them by arranging a drainage system that will quickly drain the water and ensure its strength. The study of the transverse drainage of shallow laying in the experimental installation of the road structure was carried out according to two variants of the drainage structure. Measurements were made of the modulus of deformation, soil moisture, absolute soil moisture content of the soil and the gravel layer of the substrate. After drying the soil over time, the absolute humidity decreases by about 10%, which significantly affects the value of the modulus of deformation, which increases almost 2 times.

The results of the article can be implemented in the development of road building standards for the construction of linear objects.

KEYWORDS: CAR ROAD, DRAINAGE OF SMALL PAYMENT, CONSTRUCTION, MOISTURE, DEFORMATION MODULE, EARTH FLOOR, COATING BACK, BASE LAYER, EXPERIMENTAL INSTALLATION.
