Permeable asphalt concrete and preparation method thereof
The invention belongs to the technical field of road materials, and relates to permeable asphalt concrete and a preparation method thereof. The preparation method comprises the following steps: S1, dispersing aggregate in polydimethylsiloxane, stirring for 30-100 minutes at the speed of 300-800 rpm/min, and then filtering and drying; and S2, preheating a mixing machine to 180-190 DEG C, putting the aggregate treated in the step S1 into the mixing machine, carrying out dry mixing, pouring asphalt, starting a mixer to stir for 120-150 seconds, pouring the filler into the mixer, and continuously stirring for 90-120 seconds to obtain the permeable asphalt concrete. The water-permeable asphalt concrete disclosed by the invention has excellent water permeability and relatively high strength performance.
本发明属于道路材料技术领域，涉及一种透水沥青混凝土及其制备方法。所述制备方法包括以下步骤：S1、将集料分散于聚二甲基硅氧烷中，于300～800rpm/min下搅拌30～100min，然后过滤、干燥；S2、将拌合机预热至180～190℃，将步骤S1处理后的集料置于拌合机中，进行干拌，倒入沥青，启动搅拌机搅拌120～150s，将填料倒入继续搅拌90～120s，得透水沥青混凝土。本发明的透水沥青混凝土具有优异的透水性和较高的强度性能。
