description: Theme of final qualification work: "An experimental study of the strength of asphalt mixtures, depending on the particle size distribution."
The aim of the study is to assess the degree of influence of the particle size distribution of the mineral part of the asphalt concrete mixture on the strength characteristics of asphalt concrete.
In the course of this final qualification work, the following tasks were set and solved:
1. The analysis of scientific work in the field of the issue;
2. The analysis of the influence of the strength characteristics of asphalt mixtures on the performance indicators of roads and bridge pavements;
4. The data obtained as a result of the experiment were systematized and analyzed;
5. An economic assessment of the use of the resulting asphalt mixtures.
6. Problems were noted for further research.
In the process of performing the final qualification work, eight mixtures of different particle size distribution were designed using one binder PBV 60/90 and one non-activated mineral powder. The response function was built on three parallel experiments for two optimization parameters. Variable factors were selected passages through normalized sieves as a percentage of the mass. The stone component of crushed stone, gabbro, gabbro screenings was designed according to the selected factors and their acceptable levels. Static processing of the results was performed, erroneous results that were not true were excluded. There is a general tendency to increase the strength of asphalt concrete when finding the particle size curve closer to the minimum acceptable by standard values.
