Asphalt softening point monitoring method

The invention belongs to the field of asphalt, and particularly relates to an asphalt softening point monitoring method which comprises the following steps: a) monitoring the asphalt specific gravityand the asphalt temperature in an asphalt finished product output pipe in an asphalt production process; b) performing calculating to obtain an asphalt softening point according to the monitored asphalt specific gravity and asphalt temperature data and a pre-fitted asphalt softening point calculation formula, wherein the asphalt softening point calculation formula is obtained according to the following steps: extracting a plurality of samples from the asphalt finished product output pipe, carrying out linear regression analysis on the specific gravity, temperature and softening point of the asphalt samples, and performing fitting to obtain an asphalt softening point calculation formula. According to the monitoring method provided by the invention, the softening point of the asphalt finished product can be monitore
