Problems solved by technology

Two methods are generally used in the preparation of aged asphalt in the laboratory. One is heating in a film oven. method, it cannot guarantee that the penetration of aged asphalt is the same, it is easy to cause experimental errors, and it is not suitable for a large number of tests
Another method is to use a blast drying oven to heat. This method takes too long to heat and is very troublesome to operate.

Abstract

The invention discloses an aging asphalt production device and method for testing, which includes a temperature box, a controller and a circulation part; On the outer side of the box, there is a door on the temperature box, and the asphalt flow tank, collection bucket, pressure pump and heating components are located in the temperature box, and the entrance of the upper end of the asphalt container extends out of the temperature box through the top of the temperature box , the inlet of the pressure pump is connected to the bottom of the collection bucket, the outlet of the pressure pump is connected to the inlet on the side of the asphalt holder, the outlet at the bottom of the asphalt holder is located directly above the asphalt flow tank, and the outlet on the side of the asphalt flow tank Located directly above the top opening of the collection bucket. The invention can quickly prepare aged asphalt, and the prepared aged asphalt has the same penetration and is easy to operate.

Description

technical field [0001] The invention belongs to the field of road engineering tests, and relates to a test aging asphalt production device and method. Background technique [0002] Aged asphalt is the research object of regenerant research, so the first step in researching regenerant is to prepare aged asphalt with suitable penetration. Two methods are generally used in the preparation of aged asphalt in the laboratory. One is heating in a film oven. This method cannot guarantee that the penetration of aged asphalt is the same, and it is easy to cause experimental errors, so it is not suitable for large-scale experiments. Another method is to use a blast drying oven to heat, but the heating time of this method is too long and the operation is very troublesome. Contents of the invention [0003] The object of the present invention is to overcome the shortcoming of above-mentioned prior art, provide a kind of test aging asphalt production device and method, this device and...
