Geosynthetic materials are more and more often applied to improve mechanical properties of a loose
aggregate base layer. In such a case, geosynthetic material located within layers of high rigidity must be
able to stabilize small deformations of aggregate. Geogrids of monolithic joints play such a role. The article
presents initial results of a research program based on observations of a field test section, which is used by
heavy vehicles. Hitherto results of measuring deflection, evenness and deformations in pavement layers
with sensors, show that the geogrid has a beneficial influence of on the performance of loose aggregate.
The conclusions presented at the stage of research are qualitative ones and require verification with further
research.
