Fine-grained thin overlay asphalt mixture
The invention discloses a fine-grained thin overlay asphalt mixture, and belongs to the technical field of road pavement materials. The mixture comprises a coarse aggregate, a fine aggregate, a filler, a cementing material and a stabilizer, and is characterized in that 8 mm sieve pores are set as the maximum nominal particle size, and in terms of the passing percentage of mineral aggregate with the key sieve pores, the passing percentage of mineral aggregate with a particle size of 11 mm is 100%, the passing percentage of mineral aggregate with a particle size of 8.0 mm is 90%-100%, the passing percentage of mineral aggregate with a particle size of 2.36 mm is 24%-34%, and the passing percentage of mineral aggregate with a particle size of 0.075 mm is 10%-14%. Compared with the prior art, when the mixture is used in the maintenance process of a high-grade highway, the engineering investment can be effectively reduced, and the mixture has good durability, good skid resistance and a function of reducing pavement noise.
本发明公开了细粒式薄层罩面沥青混合料，属于道路路面材料技术领域。所述混合料包括粗骨料、细集料、填料、胶结料及稳定剂，其特征在于：设置8mm筛孔作为最大公称粒径，以关键筛孔矿料的通过百分率计，其级配范围为：11mm，100％；8.0mm，90％～100％；2.36mm，24％～34％；0.075mm10％～14％。与现有技术相比，将本发明所述混合料用于高等级公路中维修养护过程中时，能够有效减少工程投资，而且具有良好的耐久性、良好的抗滑性及降低路面噪音的功能。
