Embodiment 1
[0019] Embodiment 1, the equipment for measuring asphalt stiffness and brittle point
[0020] Asphalt stiffness measuring equipment provided by the invention, such as figure 2 As shown, it includes a thermostatic device 1, a metal sheet 2 fixed on a support (not shown in the figure) arranged in the thermostatic device, and a micromotor (not shown in the figure) that drives the metal sheet to bend; The elastic force measuring device 3 connected with the elastic force measuring device, the elastic force recording device (not shown) connected with the elastic force measuring device and the digital display device (not shown in the figure) connected with the elastic force recording device; wherein, the elastic force measuring device includes pressure sensors and pressure sensors. detector (not shown in the figure). Micro motors are used to control the bending frequency and shorten the distance of the metal sheet.
[0021] At the beginning of the measurement test, first set the t...
