Comparative trials of geosynthetic materials in the base of road pavement on the section of the Central Ring Road in the Moscow Region
During the period from 2016 to 2019, a complex comparative trial was conducted by "Russian Highways" State Company on the Central Ring Road in Moscow region. Under extremely high traffic volume of 10161 vehicles per day, 22 trial section, with various geosynthetic materials below the aggregate base layer were constructed and monitored in order to demonstrate the improvement in pavement performance. This paper describes a series of static plate loading and falling weight deflectometer tests together with rut depth measurement. On the basis field tests and monitoring, polypropylene geogrids appeared to be the most effective materials for aggregate layers stabilisation. The greatest effect from the use of polypropylene geogrids was achieved by reducing the rut depth. As a result, there is an increase in the residual life of pavement, which for polypropylene geogrids ranges from 22 to 105%, depending on the manufacturer.
