| description | The article analyzes the working conditions of asphalt at high summer temperatures, and shows that in such conditions, asphalt pavement experiencing plastic shear strain. Such deformations are due to the loss of the ability of asphalt to work on bending, resulting throughout the coating thickness of the material tests triaxial compression. The authors propose to perform inspection of asphalt in the pavement on the shear strength, using for this purpose a modified criterion of Mohr - Coulomb, which includes three material parameter and a measure of theory of damage (the continuity of L. M. Kachanov or damage Y. Rabotnov). By use of integral equations of hereditary theories received mathematical model changes the integrity and damage when exposed to repeated loads. |
