Abstract

The invention relates to an asphalt warm-mixed modifier and a preparation method of the asphalt warm-mixed modifier. The asphalt warm-mixed regenerant comprises the following raw materials in parts by weight: 10 to 20 parts of devulcanized rubber, 10 to 15 parts of ethylene bis oleamide, 50 to 70 parts of aromatic oil, 5 to 10 parts of dibutyl phthalate, 5 to 10 parts of petroleum resin, and 1 to 3 parts of performance improvements. The preparation method adopted by the invention comprises the following steps: 1) heating the aromatic oil to be 120 DEG C or above for later use; 2) heating the ethylene bis oleamide to be 120 DEG C or above in a liquid state, and putting into the aromatic oil obtained in step 1; 3) putting the dibutyl phthalate and the petroleum resin into the material obtained in the step 2 in sequence to be mixed and stirring uniformly; (4) putting the devulcanized rubber and the performance improvements in the material obtained in the step 3 in sequence, and stirring for 1 hour at the temperature of 120 DEG C to obtain the asphalt warm-mixed regenerant.

Description

technical field [0001] The invention relates to the field of preparation, and specifically designs an asphalt warm-mix modifier and a preparation method thereof. Background technique [0002] During the use of asphalt pavement, asphalt will undergo complex physical and chemical changes under the action of various natural factors (such as oxygen, temperature, light, water, etc.), which will age the asphalt, which is manifested by the increase in the viscosity of the asphalt and the asphalt surface layer. It becomes brittle, the plasticity and deformation ability are reduced, and the bonding performance with the aggregate is deteriorated, which will lead to cracks, looseness, potholes and other damages on the road surface, and the road performance will also deteriorate. The performance of asphalt materials can be recovered to a certain extent by adding asphalt rejuvenation agent to old pavement materials for recycling. The recycling of asphalt pavement is beneficial to waste ...
