The Relationship of the Asphalt Mixtures Composition and Physical Mechanical Characteristics of the Coating

Abstract

In the course of the work performance the following surveys were carried out: the analysis of the information assurance of the asphalt concrete mixtures production quality, the study of the relationship between the composition of asphalt concrete mixtures and the physical and mechanical characteristics of the coating. This paper presents the results of the analysis of the two types asphalt concrete mixtures qualitative composition and its effect on the physical, mechanical and technological characteristics of the coating. It is established that the deviation of asphalt concrete mixtures in composition from the required values ​​leads to their under-compaction in the coating. It was also found that the increase in the number of inconsistencies in the composition of the asphalt concrete mixture leads to the increase in physical and mechanical characteristics that differ from the requirements of GOST 9128-2013 and GOST 31015-2002. The amount of bitumen on the asphalt concrete main characteristics, the data from the existing AP in the Belgorod Region were used as the information base in assessing the influence of granulometry of the asphalt concrete mineral part. Analysis of the particle size distribution was carried out using the laser analyzer for asphalt concrete AP 7 / 35B. The obtained data will be the basis for further study of the various parameters influence on the asphalt mixes properties, as well as improving the efficiency of the asphalt mix production control system.
