Аннотация: в статье рассматриваются проблемы в строительстве автомобильных дорог. Рассмотрены виды инновационных технологий, внедряемые сегодня в практику дорожного строительства, которые значительно повышают эффективность и качество дорожного полотна по сравнению с традиционными методами. Подчеркивается, что для активизации инновационной деятельности в дорожном хозяйстве необходимо создать действенную систему и организационно-экономический механизм организации инновационной деятельности на фоне благоприятной экономической и нормативно-правовой среды.
Ключевые слова: инновационная деятельность, дорожное хозяйство, научные исследования, дорожное строительство, инновационные технологии.
A rapid increase in motorization and rise in the number of heavy trucks and very heavy trucks in the road traffic, requires application of improved technologies for construction, reconstruction, major repairs, refurbishment of the automobile roads [1].
The modern automobile roads represent a sophisticated engineering construction, that intended for the performance of transport work and to service for the on-road services users - drivers and passengers. The conditions of the main and supporting facilities depend on the quality of construction, renovation work and improvements in the automobile roads sector [2].
For a forward - looking development of the automobile - road system is required the continuous improvement in the areas as construction, renovation, design, exploitation of the roads. At the same time, the progress in the construction of automobile roads is related with a number of problems:
• The comprehensive research and study of soil, laws of water and thermal system of the sub grade, methods of its regulation;
• Improvement the calculation of pavement surfacing and methods of integrated designing of the sub grade;
• Extensive study of mineral materials and detailed research of organic binding materials;
• Study of technology construction of asphalt - concrete covering;
• Elaboration of scientific basis about road mechanical engineering and in the area of making machines and robots and so forth [3].
With more detailed examination of the issue, it is becoming clear, that with quality organisation and observance of the work technologies, there will be a significant reserve in increasing the service life of the road structures.
There are an innovative technologies, which are at present being implemented in the road construction practice:
1. The technology of laying the asphalt - concrete coating with the aid of asphalt - concrete mixture loader. This technology allows to lay quickly and continuously of the road surface, by eliminating the temperature and grading heterogeneity of the asphalt - concrete mixture. Evenness of the surface on the international "IRI" classification usually corresponds to the "Great" or "Very good" assessment.
2. Energy- and resource - saving technology of cold regeneration of asphalt - concrete coatings and bases with the application of mobile mixer plants, provides to reduce the time, substantially makes cheaper the road maintenance by recycling of the previous road structure materials.
3. Production of asphalt - concrete mixture from the high - strength cuboid crushed stone, close - cat fraction of gabbro rock and polymeric - bitumen binder (PBB).
4. The technology of thin - layer coating arrangements. The main principle of the thin-layer coating arrangement technology is to provide the high - speed (more 8 m/min.) laying of the thin-layer (25mm) from specialized hot bitumen mineral mixture, over the binding layer from modified latex bitumen emulsion, which is distributed directly in the mixture laying process.
5. Structure of protective - reinforcing interlayer in the asphalt - concrete coating, using the steel net.
6. Geodetic accompanying the performance of road - construction work with using the electronic, completely robotic tachometer and GPS - positioning system.
7. Implementation of the machine control 2D and 3D systems on the bulldozers, maintainer, excavators. It significantly allows to increase the productivity and almost completely to abandon from the traditional manual geodetic disaggregation.
8. Design and construction of long - lived asphalt - concrete coating, that meets the requirements of the most advanced system of asphalt - concrete mixture Superpave engineering system [4].
In conclusion, it is possible to make a decision, that to realize the innovative technologies, it needs to improve the normative legal acts in the road sector, in order to adopt the documents, organizational - stimulate applying innovations and modern technologies, that enables to the road surface to withstand with the current borden and they will prevent rapid formation of the furrows on the federal roads.
