Problems solved by technology

Changes in asphalt components lead to serious asphaltene aggregation after melting of old asphalt waste, and poor compatibility of asphaltene, which in turn leads to poor dispersion of asphaltene in the regenerant, and the performance of old asphalt regeneration is not stable enough

Embodiment 1

[0039] S1: Collect old asphalt road fabrics and transport them to the mixing site for use;

[0040] S2: Use the loader to send the collected old asphalt road fabric to the hopper of the crushing and screening equipment. After being crushed by the primary crusher, it is sent to the vibrating screen for screening and classification. The particles smaller than 10mm are directly collected, and the particles larger than 10mm are directly collected. The particles are sent to the secondary crusher through the conveyor belt for crushing, and then sent to the vibrating screen for screening and classification, so that the larger particles circulate between the crusher and the vibrating screen until their size is less than 10mm;

[0041] S3: Send 800 parts of the old asphalt road fabric with a size less than 10mm selected from S2 in parts by weight into the heating drum, and heat the materials in the heating drum by burning fuel oil; in order to make the fuel burn more fully, the fuel oil...

After being crushed by the primary crusher, it is sent to the vibrating screen for screening and classification. The particles smaller than 10mm are directly collected, and the particles larger than 10mm are directly collected. The particles are sent to the secondary crusher through the conveyor belt for crushing, and then sent to the vibrating screen for screening and classification, so that the larger particles circulate between the crusher and the vibrating screen until their size is less than 10mm;

[0050]S3: Send 750 parts of the old asphalt road fabric with a specification less than 10mm selected from S2 in parts by weight into the heating drum, and heat the materials in the heating drum by burning fuel oil; in order to make the fuel oil burn more fully, ...

[0057] S1: Collect old asphalt road fabrics and transport them to the mixing site for use;

[0058] S2: Use the loader to send the collected old asphalt road fabric to the hopper of the crushing and screening equipment. After being crushed by the primary crusher, it is sent to the vibrating screen for screening and classification. The particles smaller than 10mm are directly collected, and the particles larger than 10mm are directly collected. The particles are sent to the secondary crusher through the conveyor belt for crushing, and then sent to the vibrating screen for screening and classification, so that the larger particles circulate between the crusher and the vibrating screen until their size is less than 10mm;

[0059] S3: Send 900 parts of the old asphalt road fabric with a specification less than 10mm selected from S2 in parts by weight into the heating drum, and heat the materials in the heating drum by burning fuel oil; in order to make the fuel burn more fully, the...

Abstract

The invention relates to the technical field of asphalt regeneration, in particular to an asphalt thermal regeneration production process. The asphalt thermal regeneration production process can improve compatibility of asphaltenes and improve stability of performance of old asphalt after thermal regeneration. The asphalt thermal regeneration production process is characterized in that a benzyl compound is added to melted old asphalt; the benzyl compound contains a large amount of active hydrogen, and is grafted onto a high or low molecular compound by the active hydrogen, so that a 'bridge' is set up between the asphaltenes with different molecular weights and molecular structures to improve the compatibility of the asphaltenes and improve the stability of the performance of the old asphalt after thermal regeneration.

Description

technical field [0001] The invention relates to the technical field of asphalt regeneration, in particular to a production process for thermal regeneration of asphalt. Background technique [0002] During the use of asphalt pavement, it is exposed to the natural environment for a long time, subjected to the effects of natural environment such as sunshine, precipitation, temperature changes, etc., coupled with repeated wheel rolling loads, resulting in irreversible changes in the physical and chemical properties or mechanical properties of the asphalt, namely Aging of asphalt. Therefore, the asphalt pavement has a certain service life, and after reaching its service life, the asphalt pavement needs to be repaired. If the waste of old asphalt can be recycled, it can not only save resources, but also reduce environmental pollution, which has very considerable economic and social benefits. [0003] The invention patent with the publication number CN102260058A discloses a produ...
