为了深层揭示沥青玛蹄脂的粘弹性特性,采用Burgers粘弹性模型作为粘弹性力学行为的数学描述,通过沥青玛蹄脂静态剪切蠕变试验,研究了温度对沥青玛蹄脂粘弹性特性的影响.结果表明：Burgers粘弹性模型四参数随温度升高呈负指数递减;沥青玛蹄脂蠕变柔度随温度升高呈正指数增加;沥青玛蹄脂的瞬时弹性随温度升高而递减;粘性流动随温度升高而递增;延迟弹性在蠕变初期随着温度升高先增加后减小,在蠕变中、后期随着温度升高而递减;沥青玛蹄脂的粘流动性弹比随温度升高呈正指数增加,在高温区其粘性远远大于弹性,沥青玛蹄脂表现为粘性.

英文摘要：

To further reveal the viscoelastic property of asphalt mastic,the static shear creep test was conducted through dynamic shear rheometer（DSR） and the effect of temperature on the viscoelastic property of asphalt mastic was studied with Burgers model as mathematical description of viscoelastic behavior.The research results indicate：（1）The four parameters of Burgers model assume negative exponent degression with the raise of temperature.（2）The creep compliance of asphalt mastic assumes positive exponent increase with the raise of temperature.（3）The instantaneous elasticity of asphalt mastic decreases with the raise of temperature;the viscous fluidity increases with the raise of temperature;the delayed elasticity increases initially and decreases later with the raise of temperature during the prophase of creep;during the metaphase and anaphase of creep,the delayed elasticity decreases with the raise of temperature.（4）The ratio of viscosity to elasticity of asphalt mastic assumes positive exponent increase with the raise of temperature.In the high temperature region,viscosity is far greater than elasticity and asphalt mastic appears to be viscous.
