Problems solved by technology

[0003] However, there are many deficiencies in the plant-mixed heat recycling technology, among which the heating temperature of the mixture is relatively high. Generally, the heating temperature of the plant-mixed heat-recycled asphalt mixture is 170-180°C, and a higher heating temperature will cause RAP The phenomenon of secondary aging and asphalt sticking drum will not only reduce the service life of mixing equipment, but also increase fuel consumption and dust emissions

Embodiment Construction

[0016] A method for making base asphalt warm-mix regenerant, the innovation of which is that the method includes:

[0017] 1) Add sodium α-alkenyl sulfonate to water, stir until sodium α-alkenyl sulfonate is completely dissolved, and obtain A solution;

[0018] 2) Add polysorbate 80 and triethanolamine to solution A, and use a high-speed shearing machine to shear at a speed of 2000r / min until mixed evenly to obtain solution B;

[0019] 3) Add RA-2 rejuvenator to the B solution, and use a high-speed shearing machine to shear at a speed of 3000r / min until mixed evenly, and the obtained product is the base asphalt warm mix regenerant.

[0020] Further, the mass-number ratio of the water, sodium α-olefin sulfonate, polysorbate 80, triethanolamine and RA-2 regeneration agent is 26:5:9.4:15.2:44.4.

[0021] Further, make RA-2 regeneration agent as follows:

[0022] (1) Heat the extracted oil to 100-120°C, then add epoxy soybean oil and turpentine to the extracted oil, and stir for...

Abstract

The invention discloses a method for making a base asphalt warm-mix rejuvenator. The method comprises: 1) adding sodium α-alkenyl sulfonate into water and stirring until the sodium α-alkenyl sulfonate is completely dissolved to obtain a solution; 2) Add 80-type polysorbate and triethanolamine to solution A, and use a high-speed shearing machine at a speed of 2000r / min to shear until mixed evenly to obtain solution B; 3) Add RA‑2 regeneration agent to solution B, And use a high-speed shearing machine to shear at a speed of 3000r / min until the mixture is evenly mixed, and the obtained product is the base asphalt warm mix rejuvenator. The beneficial technical effects of the present invention are: a method for making matrix asphalt warm-mix rejuvenator is proposed, and the prepared matrix asphalt warm-mix rejuvenator can recover and regenerate the performance of aged matrix asphalt under warm-mix conditions, which can effectively reduce production Energy consumption and pollution in the process.

Description

technical field [0001] The invention relates to an asphalt rejuvenator, in particular to a method for making a base asphalt warm-mix rejuvenator. Background technique [0002] With the development of my country's economy and society, green, energy saving, and environmental protection have gradually become important considerations in the process of road construction. Recycling and other waste asphalt mixture recycling methods. Due to its wide applicability and the performance of recycled asphalt mixture close to that of new asphalt mixture, hot plant regeneration can realize efficient utilization of waste asphalt mixture (RAP) and reduce costs, and has become the main regeneration method , has broad development prospects. [0003] However, there are many deficiencies in the plant-mixed heat recycling technology, among which the heating temperature of the mixture is relatively high. Generally, the heating temperature of the plant-mixed heat-recycled asphalt mixture is 170-180...
