Double-layer noise-reduction asphalt pavement based on polymer composite modification and preparation method of double-layer noise-reduction asphalt pavement
The invention relates to a double-layer noise-reduction asphalt pavement based on polymer composite modification and a preparation method thereof.The asphalt pavement is composed of a pavement base layer and a pavement surface layer composited on the pavement base layer, the pavement surface layer is made of open-graded asphalt mixture, the pavement base layer is made of dense-graded asphalt mixture, and the pavement surface layer is made of high-density asphalt mixture. Asphalt materials used in the pavement surface layer and the pavement base layer are both composite modified asphalt obtained after matrix asphalt is modified by rubber powder and polyurethane. The performance of the polymer modified asphalt provided by the invention is obviously superior to that of traditional modified asphalt, the asphalt mixture provided by the invention has better sound absorption performance, and meanwhile, the service life of an asphalt pavement can be effectively prolonged.
本发明涉及一种基于聚合物复合改性的双层降噪沥青路面及其制备方法，该沥青路面由路面基层、与复合在路面基层上的路面面层组成，其中，所述路面面层为开级配沥青混合料，所述路面基层为密集配沥青混合料，所述路面面层和路面基层中所用的沥青料均为由橡胶粉与聚氨酯改性基质沥青后的复合改性沥青。本发明所提供的聚合物改性沥青性能明显优于传统改性沥青，本发明所提供的沥青混合料具有较好的吸声性能，同时能有效提升沥青路面服役寿命。
