Problems solved by technology

[0004] The existing "T0726-2000 Method for recovering asphalt from asphalt mixture Abson method" temperature measurement method is not timely, it is easy to cause boiling liquid overflow, and the recovery of asphalt is lost due to overflow, which cannot meet the test quantity requirements. At the same time, due to liquid overflow, It may also change the composition of recycled asphalt, so that the test results cannot reflect the true shape of recycled asphalt

Abstract

The invention belongs to the technical field of asphalt recovery temperature observation, and discloses an asphalt recovery temperature observation device and an application method. The device is provided with a solvent recovery bottle, a conduit is plugged and fixed to the solvent recovery bottle, the conduit is plugged and fixed in a Florence flask, an infrared temperature-measuring device is incontact with the Florence flask through a temperature-measuring infrared line, and a thermometer is plugged and fixed to the Florence flask. The device is additionally provided with one infrared temperature-measuring device for measurement, the temperature can be conveniently measured in time, the temperature of the recovered asphalt liquid can be grasped in real time, and danger caused by boiling spilling is avoided; through the setting of the thermometer, the measured temperature and the temperature of a mercurial thermometer in a distilling flask can be compared and corrected, and the experiment accuracy is improved; and according to the device, the efficiency for asphalt recovery for T0726-2000 in a method (Abson method) for asphalt recovery from an asphalt mixture is improved, the security of the test method is increased, and experiment personnel can observe the temperature in a long distance.

Description

technical field [0001] The invention belongs to the technical field of asphalt recovery temperature observation, and in particular relates to an asphalt recovery temperature observation device and a use method. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: according to "T0726-2000 Method for Recovering Bitumen from Asphalt Mixture (Abson Method)", use a mercury thermometer to measure the temperature of the recovered bitumen liquid, and it is easy to overflow the boiling liquid. During the experiment, I felt that the existing "T0726-2000 Method for Recovering Asphalt from Asphalt Mixture" Abson's method of temperature measurement is not timely, and it is easy to produce boiling liquid. Due to the fixed recovery efficiency of trichlorethylene, the recovered asphalt is boiled If the liquid overflows, it may cause disasters such as fire and environmental pollution. At the same time, if the temperature is too high, ...
