Description
Summary:The paper reflects the results of the study conducted to determine how a free rotary instrument cuts narrow joints in asphalt pavements required for road construction. Based on the analysis of strength characteristics of different asphalt concrete grades, we developed a mathematical model of working process, and this model stands as the calculation basis. The mathematical model associates the main parameter - cutting resistance force - with the material strength values and geometrical characteristics of the working body and the working process. The results of experimental confirmation of mathematical model reliability are presented in the paper.
