Abstract

The article presents technological principles and approaches to the practical application of FluxOil series plasticizers for the production of cold bituminous road mixes, taking into account three years of production experience during the winter maintenance of public highways, city streets and roads. The object of research is cold bituminous road mixes. The purpose of the work is to establish the effect of the use of FluxOil series plasticizers on the quality and manufacturability of cold bituminous road mixes produced on their basis. The research method is a statistical analysis of practical application. The most common types of defects in asphalt concrete road surfaces are cracks, potholes and rutting. The appearance of cracks on road surfaces, over time, under the influence of rain and melt water, taking into account a certain number of freeze-thaw cycles in the transitional periods of the year (autumn-winter and winter-spring), as well as taking into account dynamic loads from the action of vehicle wheels, leads to the emergence of potholes. Winter maintenance of public highways, city streets and roads is technologically more difficult, compared to traditional seasonal road construction works. First of all, this is due to low ambient temperatures. In this regard, during winter maintenance, there is a technological need for the use of special road construction materials, such as cold asphalt concrete and bituminous mixes, the technological process of which requires special attention, knowledge and production experience. During the analysis of the practical application of FluxOil series plasticizers for the production of cold bituminous road mixes, a number of technological principles and approaches were established that significantly affect the production technology of cold bituminous road mixes, their quality, manufacturability when used at different ambient temperatures, as well as their suitability depending on the storage time. The results of the article can be used for the purpose of comparison on a par with other technological approaches to the production of cold bituminous road mixes, with comprehensive consideration of such aspects (factors) as: manufacturability, environmental friendliness, safety, quality, cost and term of use (suitability). Prognostic assumptions regarding the development of the research object – the search for the optimal technology for the production of cold bituminous road mixes for year-round repairs to eliminate potholes in road surfaces.
