Reclaimed rubber particle permeable asphalt concrete and preparation method thereof
The invention provides reclaimed rubber particle permeable asphalt concrete and a preparation method thereof. The preparation method comprises the following steps that S1, a modifier and various auxiliaries are added into matrix asphalt to be stirred and sheared, and a mixture is obtained; S2, storing and developing are carried out to prepare SBS modified asphalt; S3, the SBS regenerated rubber particle modified asphalt is prepared; and S4, the regenerated rubber particle permeable asphalt concrete is prepared. After the regenerated rubber particles are mixed with the SBS modified asphalt, light components in the modified asphalt are absorbed, and the viscosity of the modified asphalt is increased, so that the thickness of a coating aggregate asphalt film is increased, and the cohesive force among aggregate particles is effectively improved. The colloidal particles have excellent elastic performance; when internal pores of the water-permeable asphalt concrete are frozen and heaved at extreme temperature, the freezing and thawing resistance of the water-permeable asphalt concrete is improved, the durability of the water-permeable asphalt concrete is improved, the pore distribution of the water-permeable asphalt concrete can be optimized by the reasonably graded rubber particles, the pore blockage of the water-permeable asphalt concrete is delayed, and the water-permeable function of the water-permeable asphalt concrete is guaranteed.
本发明提供一种再生胶粒透水沥青混凝土及其制备方法，包括以下步骤：S1，将改性剂和各种助剂加入基质沥青中搅拌、剪切，得到混合物；S2，储存发育制备SBS改性沥青；S3，制备SBS再生胶粒改性沥青；S4，制备出再生胶粒透水沥青混凝土。本发明中的再生胶粒与SBS改性沥青混合后，吸收改性沥青中的轻质组分，改性沥青粘度增加，进而增加裹覆集料沥青膜厚度，有效改善集料颗粒之间的粘聚力。胶粒具有优良的弹性性能，在极端温度下发生内部孔隙结冰冻胀时，不仅改善透水沥青混凝土的抗冻融能力，提高透水沥青混凝土的耐久性，而且级配合理的橡胶颗粒可优化透水沥青混凝土的孔隙分布，延缓透水沥青混凝土孔隙堵塞，保障其透水功能。
