摘要

    摘要
  • 摘要: 为了分析配合比参数对纤维沥青碎石表层性能的影响,根据纤维沥青碎石的材料组成和力学特性,采用直接拉拔和正压扭剪实验对试件进行强度测试,并应用正交分析法对实验结果进行分析,得出了各配比对纤维沥青碎石表层性能的影响规律.研究结果表明:乳化沥青用量和碎石用量对纤维沥青碎石表层强度的影响水平比纤维用量和纤维长度显著;层间抗拉强度随着乳化沥青用量和碎石用量的增多而逐渐增大,抗剪强度随着乳化沥青用量的增多而增大,随着碎石用量的增多先增大后减小;当乳化沥青用量为2.0 kg/m2、碎石用量为13 kg/m2、纤维用量为0.1 kg/m2和纤维长度为60 mm时,纤维沥青碎石表层的性能最优.
    Abstract: In order to analyze the effect of ration parameter on surface properties of fiber asphalt macadam. The direct drawing and torsional sheer test were used to test strength on molding specimens which was on the basis of material composition and mechanical properties of fiber asphalt macadam. The orthogonal analysis method was used to analyze experimental results and the effect law of ration was drawn. The research shows that the influence of amount of emulsified asphalt and gravel content on fiber asphalt macadam surface strength is more significant than that of fire content and length. The tensile strength of the interlayer increases gradually with the increasing amount of emulsified asphalt and gravel.The shear strength increases with the increasing amount of emulsified while increases first and then decreases with the growth of gravel content. At last,when the amount of emulsified asphalt is 2. 0 kg / m2,stone dosage is 13 kg / m2,fiber is 0. 1 kg /m2 and fiber length is 60 mm,the surface performance is optimal.
