Environment-friendly odorless asphalt mixture and preparation method thereof
The invention discloses an environment-friendly odorless asphalt mixture and a preparation method thereof, and relates to the technical field of asphalt concrete. The environment-friendly odorless asphalt mixture is prepared from 100 to 150 parts of matrix asphalt or modified asphalt, 0.1 to 0.5 part of an odor removing agent, 0.05 to 0.1 part of a dispersing agent, 5 to 10 parts of carbonized rice hull powder, 1500 to 2000 parts of an aggregate and 50 to 100 parts of mineral powder. The preparation method comprises the following steps: S1, mixing the carbonized rice hull powder with the odorremoving agent, adding 1/2 of the dispersing agent, and uniformly stirring, S2, heating matrix asphalt or modified asphalt to 140-170 DEG C, adding the dispersing agent and the mixture obtained in thestep S1 under a stirring condition, and uniformly stirring to obtain environment-friendly odor-free asphalt, and S3, uniformly mixing the mineral powder and the aggregate, heating to 120-170 DEG C, adding the environment-friendly odorless asphalt obtained in the step S2, and uniformly mixing to obtain the environment-friendly odorless asphalt. Volatile organic matters in the asphalt mixture are treated from the source, so that the generation of asphalt flue gas in the production and construction processes of the asphalt mixture is reduced, and the purposes of environmental protection and odorremoval are achieved.
本发明公开了一种环保型净味沥青混合料及其制备方法，涉及沥青混凝土技术领域。该环保型净味沥青混合料包括基质沥青或改性沥青100‑150份；净味剂0.1‑0.5份；分散剂0.05‑0.1份；碳化稻壳粉5‑10份；集料1500‑2000份；矿粉50‑100份。其制备方法为：S1，将碳化稻壳粉与净味剂混合，加入1/2的分散剂，搅拌均匀；S2，将基质沥青或改性沥青加热至140‑170℃，搅拌条件下加入分散剂和步骤S1得到的混合物，搅拌均匀，得到环保型净味沥青；S3，将矿粉和集料混合均匀并加热至120‑170℃，加入步骤S2中得到的环保型净味沥青，拌和均匀，即得。本发明从源头上对沥青混合料中易挥发的有机物进行处理，从而减少沥青混合料在生产及施工过程中沥青烟气的产生，达到环保净味的目的。
