Abstract
Pavement structural strength is one of the main indices to determine pavement ability to carry traffic loads. The strength of separate layers
of flexible pavement structures and of the whole pavement structure can be calculated during their design. It is very important and
necessary to control whether, the strength of the newly built structural layers corresponds to their design strength in road construction and
reconstruction. For this purpose, various methods for determining pavement structural strength are used. This article studies methods for
determining structural pavement strength, assesses the strength measuring devices using static and dynamic methods. In order to identify
and compare the accuracy of test data collected by using static and dynamic methods the comparative measurements were carried out on a
base course of experimental road section by four measuring devices. Further results of the research of these results will enable to select
the most suitable measuring method. Statistical analysis and assessment of research results obtained on the subgrade of road pavement.
Keywords: road pavement; measuring methods; traffic loads; pavement strength; subgrade.
