Abstract

The invention provides warm mixed asphalt and a preparation method thereof. The warm mixed asphalt provided by the invention is composed of matrix asphalt, plasticized sulfur, an odor removing agent, and a fragrance enhancing agent. The warm mixed asphalt is prepared from components of, by weight: 100 parts of matrix asphalt, 10 to 35 parts of plasticized sulfur, 0.05 to 1 part of the odor removing agent, and 0.02 to 0.5 parts of the fragrance enhancing agent. The plasticized sulfur comprises components of, by weight: 100 parts of elementary sulfur and 5 to 25 parts of a plasticizing agent. With the warm mixed asphalt provided by the invention, influences on human bodies and environmental pollution caused by harmful gases discharged during a sulfur asphalt construction process can be effectively reduced. The asphalt can be warm-mixed with aggregate under a temperature below 135 DEG C, such that energy consumption is reduced.

Description

technical field

[0001] The invention relates to an asphalt composition and a preparation method thereof, in particular to warm-mix asphalt and a preparation method thereof. Background technique

[0002] In the past ten years, in order to prevent air pollution caused by excessive sulfur emissions in petrochemical products, environmental protection standards have become increasingly stringent. In order to meet the standards, various petroleum refining and chemical companies have continuously improved the desulfurization process, and a large amount of sulfur is produced as a by-product. In addition, the application of liquefied natural gas is also booming. Since the catalyst used is susceptible to sulfur poisoning and loses its effectiveness, it is necessary to desulfurize the natural gas before liquefaction, resulting in a further increase in sulfur emissions. The application fields of traditional sulfur are generally in fertilizers, pharmaceuticals and chemical raw materials...
