Abstract

The invention relates to an asphalt warm-mixing agent and a preparation method thereof, which belongs to the technical field of pavement laying materials. The preparation method comprises the following steps: mixing and grinding strontium carbonate, nano titanium dioxide and polydimethylsilane, thus obtaining an additive, mixing sulfamic acid, 3-chloropropionic acid and ethanedioic acid to obtain a mixed acid, then placing water, sucrose fatty acid ester and alkyl glycoside into a reactor, adjusting the pH by utilizing a sodium hydroxide solution, stirring, standing, cooling, adding the mixed acid and hydroxypropyl methyl cellulose, increasing the pressure under the protection of nitrogen, stirring, cooling to room temperature, discharging materials, collecting the discharged materials, stirring and mixing the discharged materials and absolute ethyl alcohol, standing, distilling, collecting residues, stirring and mixing the residues and additives, and collecting a stirred mixture, thus obtaining the asphalt warm-mixing agent. The asphalt mixing agent prepared by the invention can effectively improve the viscosity of asphalt at 60 DEG C and is relatively good in high-temperature stability.

Description

technical field [0001] The invention relates to an asphalt warm mix agent and a preparation method thereof, specifically belonging to the technical field of road paving materials. Background technique [0002] Warm mix asphalt technology is a kind of asphalt mixing whose mixing temperature is between hot mix asphalt technology (150-180°C) and cold mix asphalt technology (10-40°C), and its performance reaches (or is close to) hot mix asphalt mixture. Energy-saving new technology. Usually, the most common implementation method of warm mix technology is to add warm mix agent. Compared with standard hot mix asphalt technology, the temperature of warm mix asphalt technology can be reduced by 20-30°C. Warm mix asphalt technology has many advantages: firstly, the production and construction temperature of asphalt mixture can be reduced, which can save more than 20% of energy consumption; at the same time, the storage temperature of asphalt mixture is lowered, and the fluidity at l...
