Development of typical flexible road pavement catalog for regional and intermunicipal highways in Russian Federation (using the example of the Republic of Bashkortostan)
Road pavements in Russia are now working in difficult conditions of ever-growing vehicular traffic intensity. Current methodology for designing flexible road pavements has a number of serious shortcomings, where the best design experience and actual operating conditions of highways are not fully taken into account. In some cases, this leads to ineffective pavement structures design with a short service life. On many roads, rutting and premature wear of road surfaces appear already in the first years of their operation. Drainage systems are silted up in the first years of working. At the same time, geosynthetic materials are sometimes used unreasonably. The service life of roadway surfaces does not comply with the current regulations. In Russia, effective road-building materials are not yet fully used, local road-building materials and industrial waste reinforced with binders are little used. With exception of certain regions of the country, actual experience of operating various road structures with identification of the most optimal solutions is still poorly subject to consideration. Thus, there is an urgent need to develop designs of typical road pavements for various regions of Russia, which will ensure their efficient operation. To develop typical pavement designs, it is necessary to analyze existing ones in real conditions of their operation.
