Title of the articleExperimental research of asphaltic concrete rheological properties at different temperatures
Abstract.This paper, that is a part of a bigger research of temperature influence on the asphaltic bridge pavement stressed state and cracking, represents a research of asphaltic concrete creep and creep rapture strength. This caused by a long term acting of a temperature stresses, appearing in asphaltic concrete pavements. The study of creep was issued by executing experiment, where asphalt specimens were subjected to constant compression stress at different temperatures, and by description of obtained creep curves by equations of so called strengthening theory. Also material ageing was counted by comparing creep curves of new and aged asphalt. Further these equations will allow to consider stress relaxation in pavements. Creep rapture strength was observed based on the results of other authors. Accordingly to this observation a well known Zhurkov equation was selected for the accepted class of asphaltic concrete. Next creep and creep rapture strength equations have to be applied to some engineering model of asphaltic concrete pavement.
Keywords.Asphaltic concrete, creep, relaxation, ageing, creep rapture strength.
