ESTABLISHMENT OF TECHNICAL REQUIREMENTS REGARDING DRAINING ASPHALT CONCRETE

Olena Usychenko Anton Zheltobriukh

The issue of timely removal of surface water from the road surface is mandatory and is solved by providing the road surface with a transverse slope. As practice shows, this does not sufficiently protect the road surface from the negative effects of water. High operational safety, improvement of the operational characteristics of the road surface is achieved due to the removal of the accumulation of water stains from its surface, which reduce the adhesion of the wheels to the road surface. These qualities can be improved by introducing draining asphalt concrete. However, the service life of draining asphalt concrete varies greatly depending on climatic conditions, traffic intensity and loads, design concepts and construction methods. In order to further improve the current state-of-the-art instructions for the production and application of DAC to solve regional, road and climate problems, a comprehensive analysis of the currently available applications of DAC mixtures for the construction and maintenance of road surfaces is necessary. Therefore, on the basis of this, today in Ukraine it is expedient to introduce normative documents that would regulate the design, manufacture, technical requirements and performance of works according to this technology, which would allow for practical use, optimization and development of the road industry of Ukraine in this direction. Purpose. Production of asphalt concrete mixtures and arrangement of road surface from draining asphalt concrete. Assessment of the regulatory framework of the world and establishment of recommendations and technical requirements for the production and installation of draining asphalt concrete. Materials and methods. Experimental and experimental-analytical. Results. An analysis of the existing experience of using draining asphalt concrete, conditions of its use, was carried out. Theoretical studies of the process of forming asphalt concrete with a structure of interconnected open pores. Experimental studies on the selection of grain composition and bitumen content in draining asphalt concrete have been conducted. Recommendations for the production of draining asphalt concrete mixtures and the arrangement of a covering from them have been developed
