| description | The invention discloses a horizontal strain evolution process analysis method for an indirect tensile test of an asphalt mixture, and aims to solve the problem that an effective method for quantifying a horizontal strain evolution rule of the asphalt mixture under the tensile action is lacked at present. The analysis method comprises the following steps: 1, preparing a pretreatment test piece; 2, carrying out an indirect tensile test on the pretreated test piece; 3, drawing a strain-time curve; 4, the strain-time curve shows two-stage characteristic change; 5, fitting a first-stage equation; 6, determining a demarcation point of the two-stage curve in the strain-time curve; 7, the circle center of the pretreated test piece serves as an original point, the horizontal strain epsilon i and the horizontal coordinate xi of each analysis area on the surface of the pretreated test piece at the demarcation point moment are obtained, and the synthetic horizontal strain coordinate x epsilon of the horizontal strain is |
