Introduction. This article considers the phenomenon of temperature and fractional segregation of asphalt mixtures, as one of the main problems of unsatisfactory condition of asphalt concrete pavements on Ukrainian highways. The main focus is on the method of continuous installation of asphalt concrete coatings using loaders.
Problem statement. According to the State Targeted Economic Program for the Development of Public Roads of the State Value in 2020, it is envisaged to restore up to 6.5 thousand kilometers of state roads in a state of emergency, as well as construction and reconstruction of 9 bypass roads with a total length of 101.5 kilometers. In order for the rehabilitated tracks to serve at least the estimated time frame, it is necessary to envisage the use of appropriate construction techniques that will prevent their premature destruction.
Objective. Carrying out of analytical review and presentation of the world and domestic experience of the use of modern method of laying asphalt concrete surfaces on roads with the use of special anti-segregation loaders.
Materials and methods. Asphalt concrete mixtures when reloaders are used when laying them. Analytical studies of overloading asphalt concrete mixtures as a way to eliminate segregation.
Results. The questions of improving the quality of road surfaces, increasing their durability, as well as improving the economic efficiency when applying the method of laying asphalt concrete mixtures with the use of loaders are considered. The main focus is on the question of the proper use of loaders with certain characteristics and what affect these characteristics.
Conclusions. Based on the analytical reviews carried out of the world and domestic experience of using the reloaders, it has been determined that they are the best equipment today, which eliminate the segregation of asphalt concrete mixtures and determine the appropriateness of such methods of laying asphalt concrete mixtures. In addition, the advantages of using this method in comparison with the traditional laying of asphalt concrete coatings are determined. However, as the use of this method is still not well understood, but at the same time it is relevant, further research is required.
