橡胶沥青混凝土工程性质与吸声特性的研究

Study on Engineering Properties and Characteristic of Sound Absorption of Asphalt Rubber Concrete

研究以AC-20沥青胶泥作为基底沥青,用不同比例废轮胎橡胶粉末及硫磺助溶剂与基底沥青混炼制成橡胶沥青,然后拌制密级配、多孔隙、石胶泥及开放级配等橡胶沥青混凝土试体,探讨试体厚度、粒料级配、粒料粒径、孔隙率及表面纹理对其工程性质及吸声特性影响[1],评估橡胶沥青混凝土在铺面工程上应用的可行性。

In this study, AC-20 asphalt as base asphalt, rubber asphalt mixing waste rubber powder and sulfur solvent and base asphalt with different proportion, then mixing gradation, porous, stone clay and open gradation of rubber asphalt concrete specimens, explore the effect of body thickness, particle size, particle size of aggregate porosity and surface texture on its engineering properties and sound absorption characteristics, feasibility evaluation of rubber asphalt concrete in pavement engineering.
