Abstract

The invention relates to a warm asphalt modifier. The warm asphalt modifier comprises the following raw materials in parts by weight: 0.5-15 parts of disodium laureth sulfosuccinate, 0.2-15 parts of disodium cocoyl monoethanolamide sulfosuccinate, 0.2-5 parts of acid, 4.0-20 parts of inorganic micropowder and 45-95.1 parts of deionized water. The invention further relates to a method and application of the warm asphalt modifier as well as an asphalt mix containing the warm asphalt. The warm asphalt modifier well meets the requirements of road construction.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a warm-mix asphalt modifier and its preparation method and application. Background technique [0002] Warm mix asphalt mixture began in the 1990s, and refers to a type of mixing temperature between hot mix asphalt mixture (150°C-180°C) and cold mix (10°C-40°C) asphalt mixture, and the performance reaches Hot mix asphalt is a new type of asphalt mixture. The core of warm mixing technology is to use physical or chemical means to increase the construction operability of asphalt mixture, and these physical or chemical additives should not have a negative impact on the performance of the pavement. The production of asphalt mixture is a major energy consumption and environmental pollution in road engineering. At present, my country's road engineering construction is in a period of rapid development. Emission of pollutants such as gas and dust. Therefore, vigorously d...
