Abstract

The invention relates to a novel warm mix asphalt, which is characterized by comprising the following components by weight: 80-200 parts of matrix asphalt, 15-30 parts of PE wax, 2-8 parts of silica gel, 10-15 parts of artificial zeolite, 5-10 parts of elemental sulfur, and 2-5 parts of a plasticizer. The preparation method includes: taking a corresponding part by weight of matrix asphalt and heating it to 120-140DEG C, taking a corresponding part by weight of artificial zeolite, mixing the two for 5-10h, adding the corresponding part by weight of PE wax, silica gel, elemental sulfur and plasticizer, then maintaining the temperature at 140-150DEG C and performing mixing and stirring for 4-5h, thus obtaining the novel warm mix asphalt. The novel warm mix asphalt is green and environment-friendly, saves a lot of energy, and has good anti-rutting ability.

Description

technical field [0001] The invention relates to the technical field of industrial chemicals, in particular to a novel warm-mix asphalt. Background technique [0002] Asphalt is mainly used for paving applications such as parking lots, sports fields, heavy traffic roads, intersections and road turns. Hot mix asphalt is widely used in the construction process, but in a closed working environment, hot mix asphalt will release a lot of heat and smoke, which will have a great impact on the health of construction workers. Moreover, hot-mix asphalt often results in poor compaction and smoothness of the road surface. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a novel warm mix asphalt. [0004] The technical solution adopted by the present invention: a novel warm-mix asphalt, characterized in that its raw material components and parts by weight are as follows: [0005] Base asphalt: 80 to 200 parts; [0006]...
